95 f350 reverse only works when trans warms up

[My95powerstroke]

hey guys i have a 95 f350 and reverse doesnt work cold but as soon as you drive it a few minutes it is mint, someone said it could be a sensor or something just curious if it sounds like an easy job or needs a rebuild. its got 207k on it. thanks for any help!

Also when backing up a hill it doesn't want to but will do it

its a known tranny problem and can be corrected with a shift kit

Ok thanks I was told I needed a rebuild

Will that also fix my OD flashing? The trans slips when put in reverse then you rev it up a little and it kicks in and goes

[POWERSMOKIN]

it will probably fix it. OD light means theres a transmission fault. it could be a hundred different things. Its like asking "My CEL is on. Why?"

Try the shift kit, and if that does not correct the problem, you might be looking into a rebuild. Start cheap.

Also, check your fluid level if you havent already.

P.S. Dont add another post to add more information if no one else has responded, just edit the post and add in the additional details.

Thanks, yea checked fluid added a quart and put in a 24oz jug of Lucas no difference I'll try the shift kit, and I'll pull the code for the tranny to find out what it is

sounds good
