When transmission is shifted into reverse it acts like it is neutral

Was hauling a car with my flatbed trailer. Picked the car up and when I got back home I put the car in reverse and it moved good at first for about 10 feet then eventually the reverse went out.
Car drives great in forward gears. What could this be?

Good morning,

This sounds like either a clutch pack or band has failed in the transmission.

The load may have been too much for the transmission. I would drop the pan and look for any debris and see if the filter is clogged.

This sounds like you will be either rebuilding or replacing the transmission.

Okay. I'm going to drop the pan today and see. Highly doubt the clutches failed. I barely drove it before it did that.

Do not be too sure.

It sounds like something failed and usually the clutches burn up from overheating from the load.

Keep me updated.

But if that were the case why would it drive perfect in drive?
You don't think it could be the reverse servo or solenoid pack?

It can drive forward fine but have no reverse.

No to the solenoid pack. It is not electronic. Engagement of reverse is mechanical, not electronic. If it was, you would have a code stored.

After you drop the pan and put it back together, the next step would be pressure tests for main line pressure in reverse. If that is good then the only thing left is internal.

Keep me updated.

Make sure you flush out the cooler lines before installing so you do not get any debris from the old transmission into the replacement.
