No forward, no reverse, and when it is in park you can still push the vehicle by hand, so park does not work either. I had the transmission worked on and supposedly rebuilt about a year ago and it has not been driven hardly any since. It seems a strange thing that even in park it will still roll.
Do you
have the same problem?

Good afternoon,

This sounds like you have a failed axle shaft going from the transmission to the wheels.

I would look at these axles for damage. The outer CV joint is the most common failure in the axles. If we are right, and it sounds like we are, I would replace both sides.

1. Install the wheel drive shaft to the transaxle.
2. Verify that the wheel drive shaft is properly engaged to the transaxle by grasping the inner tripot housing and pulling outward. Do not pull on the wheel drive shaft bar. The wheel drive shaft will remain firmly in place when properly engaged.

I just replaced both CV axles last week, so I must have done something wrong? I will pull them to check right? Thank you I hope that is what it is and not the transmission that would not be really good.

The fact it has no park tells me it is an axle.

Look at the axles. The inner joint that goes into the transmission is common for popping out. Check the first.

Did you have a hard time getting the inner joints into the transmission?
