When shifted in Reverse or Drive trasmission 'bangs" in gear. Also shifts harder when driving. Check engine light is on with a code 76. If code is cleared condition goes away but it comes back within a week. Does anyone know if there is a solution other than new/rebuilt transmission?

A code 76 is a digital egr #2 solenoid error. Has that been checked?

Thank you for the reply. I show this a being the Pressure Control Solenoid. Is that correct? It has not been checked. The documetation I found says to make some resistance checks at the PCM connector and the 20-way transaxle connector. Is that were I need to check, and where are those connectors located (where do I look under the hood and and on the transaxle). Thank you

I have a 95 Aurora doing the exact same thing. Did your problem ever get resolved?
Thanks

Turns out my PCM was bad. Junkyard PCM $38.50, swap my original Eprom from inside the PCM. Priceless. You got the last $2 from me.
