OK guys. I know this is the wrong forum but I thought I would prolly get a quicker answer here. My father-in-law has a 97 F-250 Powerstroke with 290K on the ticker. He was pulling home his race car trailer and the tranny let go about a 1/2 mile from his house. He went to Ford and got a new tranny and TC. Installed it last night and the OD light flashes and it shifts harder than it ever has. You can actually feel it downshift. Anyone have any suggestions?? Thanks

 

Bump for you Zach.

 

Try to reset the codes and then see which ones come back.

 

The flashing light and hard shifts means that a code has been stored. The only way to know what's wrong is to have the codes read.

 

Well we went to autozoo and they couldnt clear the codes. now when you put it in reverse it kills the engine. ANY IDEAS???

 

Get the codes read. Autozone isn't capable of reading Ford transmission codes. It's stalling because the torque converter is on in reverse. Knowing what codes are stored would help with the diagnosis.

Low trans fluid can cause stalling in reverse.
