I've searched but couldn't really come up with anything. What all will i need to swap a 4l80 into my 05 silverado cc. My truck is 2wd with a 5.3. I know i will need the conversion wire harness and a new cross member, but what else is needed. also will it be possible to use the cm from a truck that came with an 80e? If so what trucks could i use one from? Thanks in advance

Sorry CM-Crossmember. i thought that the other speed sensor is in the transmission? Candidate truck for a drive shaft?

There are two speed sensors needed for the 4l80e.

I think a custom driveshaft is needed. Not stock replacements that I know of.

You can't use the crossmember from a donor 80e truck. They mounted on different spots on the frame. You either have to modify yours, or there are company's that do make them. You don't really need a conversion wire harness, you can modify yours to work. I don't think there is a vehicle that you can just swap a driveshaft out of either. I just had mine made at Denny's. Then there is the obvious tune also.

Thanks what's some of the companys that makes those crossmember's? And I know I will have to get it tuned that's the reason why I have to replace my tranny now drive shaft took it out on the dyno. Lol
