Sonnax Transmission part supplier now offers a heavy duty input shaft (part number 22121B-01).  It is designed for the hard working Dodge Diesel and the V10 version trucks.  There are several other aftermarket versions of this shaft available, but no one else in the industry uses the same techniques of can fanufacture the same high-quality input shaft as Sonnax.

Design:  The oe two piece shaft hub design is scrapped for a much stronger, one piece design that combines the input shaft and the forward clutch hub.

The sonnax shaft itself is custom forged to allow the internal grain structure of the steel to follow the general shape of the part, improving shaft strength.


Material:  The Sonnax input shaft is made from 300M, a special class of steel commonaly used for aircraft landing gear and airframe parts.  This ultra high strength steel is created through a special vacuum arc re-melting process that improves the desired characteristics of the steel.


Manufacturing:  Small details which may not appear critical can have a huge impact on durabitity.  Sonnax understands this, and over the years created a better shaft by modeling, testion and verifying innoative manufacturing processes to produce the very best results.

2006 Ford Explorer not shifting right

January 14, 2015

Customer brought us his 2006 Ford Explorer with a complaint that the transmission would not shift correctly.  He went on to tell us that another local transmission shop had rebuilt the transmission months prior.  When he picked up the Explorer after the rebuild everything was great.  However two months in the transmission would at times not shift right.  The rebuild shop took the transmission out twice.  They replace the TCU (computer that controls the transmission) and even had the dealer reprogram the computer.

We took the car in and hooked up our scanner and found no codes.  Driving the vehicle at different speeds it felt as if the throttle position sensor was not responding correctly.  We checked the TPS and found no problems.   Diving into the wiring of the vehicle we found that the transmission ECU no longer used the TPS to control shifting but the Petal Position Sensor on the gas petal. We tested that sensor and found it to be faulty.  Upon replacement the transmission shifted correctly.  Something to keep in mind.

January 14, 2015

The new Mercedes cars and SUV’s transmission now come equipped with the newly designed 722.9 automatic transmission.  In there attempt to cut out secondary repair shops they have designed the transmission control unit (computer) to be a part of the valve-body solenoid assembly.   After rebuilding and replacing this part the computer must be relearned-re-flashed into the vehicles computer system.  Mercedes refuses to do this for rebuilt after market units.

Kings Transmission of Seattle is on of the few shops in Washington State that can rebuild and replace to ecu and has the computer programs needed to replace and update the software saving the sky high prices of having the dealer replace the transmission with a new unit.

If you find yourself stuck with the high dealer prices and limited options  give us a call at 206-624-1859.

Ford’s Bad Transmissions Explorers

Their higher mileage transmissions are bound to fail

The Ford Explorer has a huge problem with transmission failure, mostly from the early 2000s — especially the 2002–2004 Ford Explorer.

Signs of Transmission Problems in Your Explorer

Ford Explorer Transmission Problems

Transmission problems in Ford Explorers are one of the most commonly complained about issues of any car on the road. With a typical repair cost over $2,000 it’s easy to see why owners are so upset. One dealer even claims that 1 out of every 10 Explorer’s from the early 2000 model years will have transmission failure at some point. The Explorer model years with the most transmission complaints are the early 2000 models.

What signs can you look for when it comes to transmission failure? Is your transmission slipping between gears, making a clunking / rattling / grinding noises when accelerating or are you suddenly having trouble shifting between gears? You should bring your SUV in immediately to get serviced. One of the major problems is the solenoid packs Ford uses to shift the transmission.  The repair of the solenoids cost under five  hundred dollars.  Make sure you have that checked before you replace your transmission.  Warning the dealer will not just replace the solenoids.  They will sell you a new transmission with new solenoids in it.  Seattle Transmission repair.

BMW Firm Engagement (D) Harsh downshifts

posted by Marks33527 @ 8:59 AM
September 25, 2014

Audi or BMW cars equipped with the ZF5HP transmission may exhibit a firm engagement in the drive position accompanied with a hars coast-downshift.  This condition may be worse the warmer the tranmission gets.  Mostly effecting cars 2003 and newer.

The cause may be a EDS 1 Solenoid.  If this solenoid is going bad it will cause high valve pressure which can cause high line pressure. 

If you are having these problems give us a call at 206-624-1859 Kings Transmission of Seattle.

Five clues to transmission problems

posted by Marks33527 @ 8:36 AM
September 12, 2014

If you drive a car with an automatic transmission, you may have thought about what would happen if the transmission started to fail.

Here are five signs of transmission problems you should not ignore:

1. Slippage

If you’re experiencing automatic transmission slipping, it can feel like you’re driving in a certain gear and then it changes for no apparent reason. The noise from the engine may change in pitch or start to sound like whining. Your car may also seem like it’s struggling, is suddenly underpowered, or isn’t accelerating like it should.

2. Rough shifts

Your car may feel like it’s refusing to change gears as it normally does, or the gear shifts aren’t very smooth. Sometimes you can feel or hear a noticeable “clunk” or “thud” when the car shifts gears. You may also notice the car has difficultly getting up to speed.

3. Delayed engagement

If this symptom occurs, you’ll notice a delay before the car actually engages into drive and starts moving forward. When you shift out of “P” and into “D,” there may be a long pause where the car revs the engine as you give it gas, but it’s not moving forward as it should.

4. Leaks

Transmissions are generally sealed units that should never leak fluid. If you’ve noticed leak spots on your driveway or garage floor, lay down cardboard under your car in the front and middle to determine if they’re active leaks.

If your transmission is leaking – fluid is bright red, but can also be a dark red or brown – visit your auto service shop. Before refilling any transmission fluid; factory specifications should be followed because overfilling can create a bigger transmission issue.

5. Dashboard warning lights

A warning light alone, like the “check engine” light, typically doesn’t mean you have a transmission problem, but if any of the above symptoms are occurring in conjunction with an illuminated warning, have it diagnosed by a professional. A warning light typically means the computer is generating an error code that can be checked with a shop’s diagnostic equipment. For transmissions specifically, “P0700” is a code that can indicate a general transmission problem.

Transmission repair considerations

Costs related to repairing your transmission can be as little as $150 or so to replace a defective transmission solenoid and up to $2,500 or more to repair or replace an entire transmission. You should definitely research what shops in your area specialize in transmission repair and call or visit them to get an estimate. If your normal mechanic doesn’t specialize in or provide transmission repair, they should be able to recommend a specialist.

If you’re not comfortable driving your vehicle due to transmission issues, have it towed in. Most reputable shops will want to test drive the vehicle to attempt to replicate the issues you’re concerned with, but that may mean they need additional time to diagnose the problem. Any towing and diagnostic fees should be included in your estimate.

Questions to ask of transmission repair shops

Before authorizing any transmission repair, ask if they plan on replacing parts and where those new parts will come from. If they’re rebuilding the existing transmission or replacing it with a new one, ask what the warranty is. An industry standard warranty is 12 months or 12,000 miles (whichever comes first), but you may be able to purchase an extended 24-month/24,000-mile warranty or even a 3-year/36,000-mile warranty.

You can also ask if your transmission specialist is a member of or certified by the Automatic Transmission Rebuilders Association. No matter what, make sure you ask any questions about the repair process before it takes place, and that the shop leaves you with a good feeling about trusting them with what could be a costly repair.

Ford 500 Transmission Problems

The automatic transmission may develop shifting concerns. On lower mileage vehicles, upgrading the software in the powertrain control module (PCM) and the transmission control module (TCM) may correct the problem. As the mileage increases, internal transmission damage can occur. Repairs could involve replacement of the valve body or a complete transmission rebuild. Whenever major transmission repairs are made, it is important to be sure the PCM and the TCM have the latest software updates to help prevent these issues from reoccurring.

How to know if you have a transmission problem

posted by Marks33527 @ 7:58 AM
September 9, 2014

Your car’s transmission is one of the most important parts of your vehicle, and transmission problems with your vehicle can result in rendering your vehicle completely undrivable. The transmission in your vehicle is the part of the car that directs the power from your engine to the driveshaft which in turn helps to turn the wheels on your vehicle. Following good preventive maintenance procedures for your transmission will always help your transmission perform better, last longer and require fewer repairs. However, in the event that your transmission does have problems, knowing what some of the more common types of transmission problems are can help you quickly diagnose and repair them. So, here is a list of the most common type of transmission problems.

Low Fluid Levels or Leaks

Low levels of transmission fluid or transmission fluid leaks are by far the most common type of transmission problem. Low levels of transmission fluid are usually caused by leaks in the transmission system itself. The seals in the transmission or driveshaft may become faulty and leak fluid. Occasionally, transmission gasket seals may need to be replaced to seal the leaks in the transmission. On some occasions, transmission fluid may be contaminated from coolant in the radiator. This is called cross-contamination and does occur on occasion.

Generally speaking, symptoms of low fluid levels or fluid leaks will include gear slippage or slow shifting. In the event fluid is very old or contaminated, the fluid will need to be changed or the transmission completely flushed and refilled.

Torque Converter Problems

Torque converters and transmission can be the source of several types of problems that can result in transmission damage or failure. One of the most common problems associated with the torque converter is worn or damaged needle bearings. If the needle bearings become warm, you will generally hear strange noises coming from the transmission while in driving gears. When the vehicle is in neutral, the transmission will probably not make any strange sounds, but when in a driving gear will make grinding or brushing sounds.

Solenoid Problems

The solenoid controls the flow of fluid throughout the transmission. Many times, the solenoid can become damaged because of insufficient fluid levels or other electronic problems with the solenoid. Problems with the solenoid are usually similar to those of inadequate fluid levels or fluid leaks. If your vehicle’s transmission is slipping and there are no leaks, the solenoid is the next item that you should check.

Clutch Problems

The clutch is located within the torque converter and can occasionally become jammed. When the clutch jams, the solenoid may become locked and the amount of transmission fluid in the torque converter may not be correctly calculated. These type clutch problems in the torque converter also appear very similar to low fluid levels. Clutch problems will also normally cause violent shaking underneath the vehicle and may produce very high heat levels in the transmission. You will normally also notice a very sharp drop in the power output of your engine.

Nissan Transmission Problems SUV

posted by Marks33527 @ 9:54 AM

Today we are working on another in a long line of Pathfinders that has water in the transmission.  It is not only the Pathfinders but it also includes the Frontier and Xterra SUV’s.

The radiator that Nissan put in their SUV’s breaks down and the water and transmission fluid mix.  The water gets into the transmission and de-bonds the friction material off the clutch plates.  That in itself would be bad, but worse than that is that the computer that controls the transmission is inside the transmission.

Once water enters the computer the transmission is finished.  A rebuild at most shops requires that the computer and valvebody to be replaced.  This adds another thousand dollars to a expensive rebuild to start with.  Seattle Transmission in the SODO district now has a line on the second design computer.  No longer are we at the mercy of having to buy the dealers expensive parts.

Below is the recall on the radiator problem.  Most cars affected are now out of warranty.

Nissan has decided in the interest of customer satisfaction, to further extend the warranty for the Radiator Assembly on all 2005-10 Frontier, Pathfinder, and Xterra vehicles equipped with automatic transmissions. On a small percentage of vehicles, an internal crack on the oil cooler tube may occur leading to internal leakage of engine coolant. While the majority of vehicles will not experience this issue, for customer satisfaction purposes, Nissan has decided to further extend the coverage of the New Vehicle Limited Warranty on the radiator assembly, subject to certain customer co-pays that vary with age/mileage. The New Vehicle Limited Warranty coverage on applied vehicles for the Radiator Assembly (original terms 3 years/36,000 miles) will be extended from the current extension of 8 years/80,000 miles to 10 years/100,000 miles (whichever occurs first), including damage, repairs, replacement, and towing resulting from this issue. With the additional extension, the following warranty coverage and corresponding customer co-pays will now apply: Up to 8 years/80,000 miles (whichever comes first): No customer co-pay After 8 years/80,000 miles (whichever comes first) up to 9 years/90,000 miles (whichever comes first): Customer co-pay is $2,500 After 9 years/90,000 miles (whichever comes first) up to 10 years/100,000 miles (whichever comes first): Customer co-pay is $3,000 As with the prior extension, this extension of warranty on the radiator assembly will cover damage caused to other affected components, including the vehicle transmission, as a result of an internal leakage condition in the radiator assembly. However, existing powertrain coverage applicable to the transmission (5 years/60,000 miles) otherwise remains unchanged.
