Bump...
Since the trans seems OK when cold, but not hot, that implies that there is a chance, but just, that the clutches have enough material, but the clutch-pack piston seals are too hard and not sealing the hot, thinned-out ATF. At this point you can try a fluid change with a seal conditioner, just to see if it works in your case. I'm have always used Valvoline MaxLife ATF in these transmissions, and should get around 6+ quarts in it if you haven't driven the car for many hours, and pull the pan. You should do this anyway to see if there are any debris in the pan, and to change the filter, unless you decide to just get a replacement trans instead.from my experience that code in the trans (incorrect gear ratio) means a bad transmission..what you can do is unhook the abs and to move it
Well I did have the car running and I did try to clear them, they wouldnt clear and the trans stayed immobilized. But if I shut the car down (I had to jump it due to a dead battery) The transmission would move until the "abs fault" appeared and it was back to square one.To clarify, by "unhook the ABS", he means to disconnect the electric connection on the side. It has a slide-lock feature that keeps the connector in place.
Some of those voltage errors you list are likely caused by disconnecting the battery or the jump that you had to give it once the battery died. I'd recommend clearing the codes and firing it back up to see if they reappear
Yeah it was down to single digits here last night and below 0 with the wind chill. Those temperatures are supposed to stay until next week sometime so I'll do that exact thing then and see if anything is in the pan. I was debating too on removing the valve body and dissembling it and cleaning everything. I'm not sure if that would do anything as to there are no codes related to the valve body.Since the trans seems OK when cold, but not hot, that implies that there is a chance, but just, that the clutches have enough material, but the clutch-pack piston seals are too hard and not sealing the hot, thinned-out ATF.

What trans dipstick??? There's no dipstick on the ZF 5HP19 transmissions.pull the trans dipstick and take a good smell-
Just to make sure everyone is on the same page.....I know you meant well.pull the trans dipstick and take a good smell- it should not smell like it's burnt. if it ys brown to black, you have a problem. best to have a trans shop look at it before making the decision to change out/rebuild.
