Hello I live in missouri and just bought a chevy cummins project it is a crew cab long bed with a straight axel it has a 12valve with a 4l80e

 

 

How is the 4L80 holding up to your 12valve ?

Any mods to the motor ?

 

As of right now the stock 4l80e is bad this is whats going in there hope it holds!!!

4L80E StreetFighter® Transmission 4X4 97-up #271500
