I just had my transmission rebuilt on my 01 WJ quadre-drive. The dreaded 545-rfe. My jeep has 146k miles and everything has been maintained properly. The CEL is not on.
When i picked my Jeep up from the tranny rebuild, I immediately noticed a vibration/rubbing and growling sort of sound from the underside. It is most noticeable in reverse, and at low speed. It seems to be worst when going up hills, or when accelerating hard. I do notice vibration at all speeds and throttle position. It really depends on how much throttle is applied at any given speed how bad the vibration is.
My guess is a U-joint? I don't know much about transmissions, etc. , so I don't want to just throw parts at it hoping to solve the problem. The transmission rebuild hurt enough!
It just doesnt feel the same as it did before the rebuild. It seems like it's losing power. The engine sounds like it has to work harder, and it doesnt seem to accelerate as quick as before.
Any suggestions would be appreciated.
