4l80e/NP205 Swap

[bilfman]

I have found the rare 1991 4L80e/NP205 combo and am taking the plunge and putting into my 79 dually 4x4. I have done some research on the net and have found several tips on getting the unit to work. I have wrenched vehicles for many years and have several complete restos under my belt, but this computer controlled tranny is totally new to me.

Has anyone done such a switch, I am just networking to try and have as much information as I can. I see a Throttle position sensor is required and think that I have that setup all locked in the ol brain.

Is a map sensor required? Anything else to watch out/prepare for? Sensor, electrical?

Driveshafts and crossmember are handled, that stuff I have done many times in the past.

Thanx in advance!
