my transmission bumps every time it slows down to 30 mph, dealer said needs to be rebuild. needs help!!!
Tell us year of the van and mileage, How many estimates, 3 is preferred, a Ujoint could be a possibility!
Those are known for this actually…I believe it is caused by a shift solenoid engaging too early… You should pay a transmission shop to run a diagnostic on it to see if a new solenoid is in order…or if its a transmission computer problem.
This usually means you are going into limp mode. Have the computer scanned and post the code/s here and we can go from there.
