Question Details

Sometimes when I am driving, my car will seem to shift when I come to a stop sign or red light. When I accelerate the RPM will jump up really high and I can't hit the gas without it revving up high. All I have to do to solve this issue is to stop and restart the car. It is happening around 4 to 5 times a week. I had the transmission filter and fluid replaced because I was told that this is probably the issue, but it is still happening. Do you know what this issue may be?

Is the check engine light on?

The reason why I ask if CEL is on, is that it can have codes that point to a bad valve body. There is also the possibility that the 13 pin conntor at the tranmission is soaked in trans oil and causing communcation issues between the valve body and trasmission control unit (TCU) It is very easy to check the 13 pin connector on the 722.6 transmission.

I agree. You need to check the 13 pin connector for leaks.

Check Engine Light is not on, but I will look into the pin connectors. If my mechanic just replaced the transmission filter and fluid, would he have noticed that about the pin connectors?

No he wouldn't have noticed. It didn't have to disconnect the 13 pin conector to change the filter and fluid.
