im currently doing 4wd swap and I have some tranny questlions. my truck originally came with a c6 2wd 5.0. I alreay have the 4wd ttb bolted up to the truck my next issue is the tranny swap im fixing to do. I have a e40d fresh rebuilt from tranny shop. im trying to figure out how the over drive works though. my cluster shows prnDd1. will that work with a e40d or do I need a different cluster and possible the overdrive switch?

 

come on guys I know somebody has some info! TIA

 

You will be fine with the cluster you have, I'm not sure about the switch though.
