I had been to several different shops, trying to figure out what the problem was with my car’s differentials. It was very frustrating because different shops said different things. I finally got the peace of mind and the comfort that I needed knowing that a transmission shop got me the correct Seattle differential diagnosis.
I found a shop that knew what they were talking about when it comes to differentials and I trusted them to do the right job. I knew that I could trust them because they have been working on differentials for years. My Seattle differential diagnosis from this shop fixed the problem and I am very glad that I chose them for my repair work.
I was involved in a car accident a few months ago and I needed some extensive repair work done on my transmission. Luckily, I found the perfect shop that has the knowledge and expertise in transmission services so I trusted them to fix my car’s transmission system. They were able to get the job done well and done quickly.
The transmission repair that was done has made my car run like new ever since. I even got a free estimate and towing to their shop. This is very rare, I have always had to tow my own car to the repair shops that I have dealt with in the past. I got a comprehensive repair of my transmission quickly thanks to Seattle transmission repair.
I love getting Seattle transmission maintenance because the shop assures that my car keeps running smoothly. I have an older car and the transmission has always been working very well, thanks to the maintenance work that I do on it. Cars need regular maintenance in order to stay protected from unexpected break-downs.
Break-downs still happen even if you take good care of your care, unfortunately, but these break-downs can happen less frequently if you give your car good maintenance. Maintaining the transmission system is one of the most important things to maintain and I rely on Seattle transmission maintenance to get the job done well.
What is a dual mass flywheel:
One of the major issues all the manufacturers have is the dual mass flywheel (DMF) which seems to need to be replaced every time that you need a clutch and that puts the price of clutch replacement up to around £1000 which on a car that has probably done in excess of 100,000 miles will probably make it uneconomical to repair. So the first thing to understand is what a dual mass flywheel is designed to do. The dual mass flywheel is an aid to making the gear change on your car lighter and more positive while also making the engine and gearbox smoother and quieter. So how does it work, in order to make an engine smoother you need to increase the mass of the flywheel but as you do this the mass of the gear train effectively becomes less as a proportion of the total mass that is in motion and you will get noise, rattles and vibration from the gear train, in order to get around this you would traditionally have increased the mass of the gear train which in turn would mean that the syncro’s (the brake that matches the speed of the gears that are about to be engaged) also had to become stronger and there fore the gear change becomes heavier and more agricultural. To get round this you have to increase the mass of the gear train without increasing the mass of the gears, this is done by splitting the flywheel into two separate masses (hence the name “dual mass flywheel”), one mass that is attached directly to the engine and one mass that is attached directly to the input shaft of the gearbox, these two halves are then separated from each other by a damper which stops the natural vibration of a large high capacity, high compression engine being transferred to the gearbox.
Customer brought us his 1998 Ford Explorer with the complaint that it took forever for the transmission to shift into 3rd gear. Upon inspection and test drive we found that third gear was missing. If you kept climbing in speed it would shift into 4th Gear and because it was a five speed automatic it would then shift into 5th gear.
We found that the servo was broken and not applying the bad correctly. After replacing the servo we again test drove and confirmed our fix. No it does not require a rebuild.
Some sounds emanating from your vehicle may be your automatic transmission warning you that something is seriously wrong. Here are five common transmission sounds that are worth looking into:
1. A high-pitched whining noise that gets worse in reverse could mean that you have a clogged transmission fluid filter. A great test for a clogged filter is to raise line pressure without raising engine rpm. You can do this by shifting into reverse. So, if the volume goes up in reverse it indicates a clogged filter . The noise is produced when the transmission fluid is restricted from flowing through the filter. This is not only a problem, but a symptom as well. Fragments from the automatic transmission may have clogged the filter and the source of the debris is the real problem. A clogged transmission filter can also be symptomatic of severe automatic transmission damage.
2. Whining or grinding noises when driving can mean that the planetary gear set is damaged. Automatic transmissions use a planetary gear system that consists of a single center gear, a large ring gear around that with internal teeth and multiple small gears in between the center and ri g gears. This arrangement allows for a variety of gear ratios that can be shifted very easily, but if one part of the system fails, it often renders the whole system inoperable. A failing planetary gear set will cause widespread damage if not corrected immediately. If you hear these noises, you should stop driving and have the vehicle checked for problems.
3. If your vehicle has a few years on it you may begin to notice harsh or soft shifting or delays when your automatic transmission is shifting through the gears. This may be due to your TCM’s inability to compensate for excessive transmission wear and tear. What’s a TCM you ask? Well, it’s your transmission control module – an amazing computerized device that constantly monitors and manipulates your transmission’s components and adapts as normal wear and tear builds. But adaptation can’t hold wear at bay forever. Eventually wear overcomes the TCM’s ability to compensate and becomes apparent to you in the form of harsh or soft shifting, delayed engagement and shift timing problems.
4. If you hear gurgling noises coming from your transmission, this is usually an indication that your transmission fluid level is very low. Because there is not enough fluid to fully enter and lubricate the system, the air pockets interact with the fluid to create the sound. The best, and first, indication of low fluid levels is if the transmission falls out of gear when you come to a quick stop or during a hard turn. If a gurgling sound is accompanied with this first indication, your fluid level is dangerously low. Keeping your transmission full of clean automatic transmission fluid is the best thing to do to avoid transmission problems.
5. A constant whining sound, one that may change in pitch as you drive, may be indicative of a problem with your torque converter. The best indication of a torque converter bearing issue is that you hear the whining in gear (any gear) while stationary and then the sound goes away in park or neutral. Understanding how the torque converter functions can help identify whether or not a torque converter problem is suspected.

Never ignore the sounds your automatic transmission makes. These could be desperate cries for help and you should take your vehicle to your local ATRA Member Shop immediately before further, and possibly irreparable, damages occur.

Three times now we have taken in a Ford Focus with the complaint that the customer could not shift the transmission into one or more gears. Each time they were sure that something had broken inside the gear train of the transmission. However once we took out the shift tower on the transmission we found a broken roll pin. Don’t over think it. Pull the shift tower and check the pin before you pull the transmission and waste time and money. Seattle Standard Transmission Repair.
We had a 2004 Ford F150 brought to us with a grinding noise while in 2 wheel drive mode. Once transfer case is shifted into the four wheel drive mode the noise went away. Could not make it happen with all four wheels off the ground.
What we found was a broken vacuum hose that ran from the IWE solenoid on the fire wall to the right front wheel. This is how the hubs are locked in on the front. Without vacuum the hubs are trying to engage but can’t. This causes a grinding noise.
This week a customer brought to us his 2005 Mini Cooper S with the check engine light on. Upon inspection we found code P1611. The transmission was in limp. P1611 which is defined as Serial communication w/transmission ecu. First thing we did was unplug the connector at the transmission and found that fluid had leaked through. We replaced the wire harness with a new one and cleared the code. Upon start up we attempted to engage the transmission into gear. Again the P1611 code came right back. Further research we found that the 5 amp fuse in the drivers kick panel marked f-13 was bad. The fuse also controls the reverse lights and transmission communication. Once we replaced the fuse all was well. Code gone and transmission shifts great.
Some 2009 and later Edge and Flex Taurus and Explorer transmission may have a sluggish acceleration or hesitation feel during acceleration, or during a rolling stop 0-8 mile per hour followed by a harsh bump feel. Also may feel a slip on take off from a stop followed by a harsh bump.
There is a valvebody modification with a new calibration that will change and correct this condition.
