We replace the 700r4 trans in my brothers 91 caprice wagon. 305 tbi. Now that we have replace the trans, it will not stay running at all. We found out that the pump was not coming on, so we replace that. Still does not run at all.It will start up and not stay running when you push the gas. It will stay running when you spray ether into the tbi. We have replace the TPS and IAC and still not running correctly. It was running fine before we replaced the trans. Anything we could have done to make it run like this. Need help ASAP.
