I've got a '93 4L80E from a 6.5 turbo diesel 2WD C2500 with the manual injector pump. I've got the trans PCM/ECM and wiring from the trans to the ECM (simplest 4l80e pcm, right?). I'm considering putting a 2002 4.8 motor in front of this tranny in a custom 2WD vehicle. The 4.8 is from a Tahoe with an automatic (4l65e?).

1. Will the tranny bolt up? Input shaft length issues? Crank bolt pattern?

2. Can I use the tranny controller to control the trans and the engine controller to control the engine, keep them separate?

3. Should I switch to a manny tranny ECM for the engine? My understanding is that the diesel tranny controller needs some sort of rpm signal from the motor (hooks to a sensor that goes in the distributor/vacuum pump hole in the 6.5 block).

4. Is there any way to control the 4L80E with the 4.8 ECM?

Any ideas?
