Hi Gary. Thanks for contacting us today. If you are using the old converter from the previous transmission, it’s likely that is the source of your problem. However, there could be issues with shift solenoids or other electrical components - or the replacement transmission itself has damaged inner seals or other faulty components. You might want to have a professional mechanic come to your location to help diagnose your issue, as there are several variables.

The transmission wiring may be wired different since it was from a 4.3 engine and you also did not mention what year the new transmission is since it may also be cause of it not working. If it is from same year then you may not be producing pressure from the transmission front pump or converter is bad. You should have the fluid levels checked and then check the other items listed and also scan the computer for any transmission codes so they can be diagnosed.
