Does the transaxle effect your vehicle shifting gears?

If the cv joints are going bad then it will sometimes jar real good when slowing down or accelerating quickly or turning even. It would effect slippage though. This will have to be adjusted by a good tranny shop. It could be many things when it comes to newer transmissions. It is better left to someone that has all the proper diagnostic equipment. Bc it could just be a bad shift solenoid and you wouldn't no that without running diagnostic pressure and computer component tests. I hope this helps you.
