Transmissions are complex, integral parts of your vehicle. As time has gone by, they have become more and more complex, to provide better efficiency three speed manual gearboxes have given way to computer-programmed, nine-speed automatic gearboxes. Unfortunately, the same problems can still occur. If your vehicle is starting to have sluggish shifts, will not shift into drive or reverse, or emits grinding sounds, you need to bring it in to Eastside Bavarian for repairs.

Your transmission is integral to a safe driving experience, so when the time comes to get it serviced or repaired, you can bring your vehicle to Eastside Bavarian. Please give us a call at 425-391-1990 or schedule an appointment online.


Your car’s transmission is responsible for making sure the right amount of power goes to your wheels to drive at a given speed. Similar to gears on a bicycle, an automatic transmission will shift you to a higher gear when you accelerate and will shift to a lower gear when you slow down. A transmission has its own designated fluid that makes sure all the gears are spinning smoothly. It is important to get this fluid changed at recommended mileage intervals to ensure your transmission is functioning properly.


The power generated by your vehicle’s engine first flows through the transmission before it reaches your wheels. The transmission controls the torque available to the drive wheels for different driving conditions. This is why you might change gears when you are driving uphill; you will need more torque in order for your vehicle to go up the hill efficiently.


We at Eastside Bavarian in Issaquah recommend changing your vehicle’s transmission fluid earlier than when most manufacturers recommend:

Automatic Transmissions:

Generally, we recommend the fluid and filter be changed between 60K-85K miles (depending upon your make and model).

Manual Transmissions:

Generally, we recommend a transmission service be performed every 50K-75K miles (depending upon your make and model).

Some signs that something is wrong with your transmission include:

There is a grinding or shaking sensation in gear.

If your car grinds or shakes when you change gear, there is an issue with your transmission. This problem usually gets worse with time, so it is best practice to bring your vehicle to an auto repair shop as soon as you notice this problem.

Your vehicle makes whining or clunking noises.

These noises usually mean your transmission fluid is breaking down or is there an internal problem with your transmission.

Your vehicle will not engage when in gear.

If there is a delay in your car responding when you change gears, your transmission fluid could be breaking down or there may be a problem with your vehicle’s computer system. However, if neither of these things are the problem, there is an issue with your transmission.

Your “Transmission” light is on.

While this could mean several things, this is your vehicle’s computers way of telling you there is a problem with your transmission.
