Transmission bumps

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.
