How do I troubleshoot a 1994 Cadillac Devilles‘ transmission. It won‘t come out of 2nd gear.
does it register trouble codes on the dash? could be electronic issue if there are codes but i doubt it . car is probably not worth a transmission unless it is in extremely good shape
You best let the tranny guys do that. You could get a head start by scanning it. I believe there are some tranny codes you can retrieve.
Unless you have experience rebuilding automatic transmissions, leave it to a professional. Get several estimates, then choose who you want to do the work. Automatic transmissions are very complex and require special tools. You really don't want to try this at home if you have no experience. If you need to save some money, call a salvage yard and see if you can buy a used transmission.
