1993 DeVille Tranny

Recommended Posts

Hello to all, new to the forum. I am looking at a 1993 Sedan DeVille. Unsure of the engine. Current owner says car runs great. I heard it run and it is quiet as a mouse. But the owner says that every once in a while the tranny wants to stay in third gear. Owner is a mechanic and claims that there is probably a glitch in the computer. Says he has looked at the tranny and says it looks good. Any thoughts here. Car has over 100k on it.

LOL owner is a mechanic, car has a problem, but owner has not fixed it? Assume the transmission needs a rebuild and price it that way.

I love it when the ad says, "car only needs a $50 repair to be good as new" or whatever. If it only needs a minor thing wouldn't you do that before you try to sell it then not have to mention the thing at all?

I agree fully. When a mechanic is selling a car with a supposed simple problem, it is never a simple problem.

Welcome to the forum :lol:

How about this. My step son bought this thing. Owner says that he replaced a 15 amp fuse in the interior fuse box and that cures the problem of the car staying in high gear. I drove it and it drove fine. Gotta love them Caddy's ride. But it appears that the fuse has blown again and it stays in high. Any ideas. Fuse too small or is it another issue. You can manually shift the tranny and it works. so it must be something telling the tranny not to shift.

Pull the diagnostic trouble codes and post them here. There's a very good chance that they will tell you what is wrong, or at least point you in the right direction. Posting them here will help us to help you. This link will tell you how to pull them.

There is a table inside of the fuse box which tells you what circuit a particular fuse is responsible for. That could point you in right direction too.

Here goes. The fuse is in slot #5 and is marked for ERLS.

There is an intermittent short somewhere. Read this up, it is a different car but the same powertrain:

I would recommend buying a factory service manual for the car - they are available on ebay for reasonable prices. Once you have a shop manual, study the circuits that the ERLS fuse feeds. My guess is there is a intermittent short in the wiring somewhere caused by something that pinched a wire or rubbed through the wire insulation.
