just bought this car and am getting the bugs out. it's been sitting awhile.
Got the brakes up today and drove it up to shift speed for the first time.
It runs and shifts great through all forward gears, But reverse slips with any uphill grade or resistance.
you can feel it go into and try to move while idling, but when you give it a little gas it just slips. I put it into reverse while it was jacked up to do the brakes. back wheels spun backward like normal. but with it on the ground, it slips. HELP and thanks shift pattern is PNDSLR

 

If it has been sitting a while maybe it needs the trans oil and filter changed

 

that is on the agenda. was hoping to get some helpful info before dropping the pan

 

Try the oil and filter change. If no go, then either reverse clutch or piston apply seals for the reverse clutch have dried up. Good luck with the oil and filter change. BTW filter is about 65 dollars.

 

IF you can't get a filter and pan gasket at Summit or a local auto parts store then Fatsco should have one.

 

Thanks for all the replies. I took it to may tranny man, we'll know soon.

 

Tranny man said reverse cones were worn......(cone shaped rings) $250.00 in parts and $300 labor and were in bizness agin. Also resealed and no leaks now. Thanks for everyones input on this. case closed

 

Not quite closed, post some picture of you car in the vintage car forum for all of us 50's guys (others might like to look as well)

 

Will do soon as the sun shows it's face again, so we can get some decent pics. Been cloudy and rainy for over a week here. thanks

 

Very reasonable repair, this guy didn't gouge you at all. Good deal!
