Installing 4L80E trans and wiring up questions
Wanna bolt up a 1993 4L80E trans to my 5.3L engine. The pcm i have is not set up for an automatic. I have a pigtail for the trans and one for the PRNDL switch. I do have access to hptuners to activate the change the parameters of the pcm to run an auto trans though.
The flexplate i have on the 5.3 is the warped one and i use a spacer for the converter for the current TH700R4. Would I have to reuse this spacer for the 4L80 or just drill the holes in the flexplate and bolt the converter up?
Next is questions for the wiring. Is it necessary to run the PRNDL wiring to the pcm? Also, does anybody have a rundown of where all my wires from the trans and PRNDL pigtails run into the pcm?
I have about a week off for holidays and would like to get this 4L80E into my car and operating if possible. Thanks

No, the PRNDL was only for the trucks (controlled the gear indicator on the dash).

Well, i ran into another glitch with the wiring. I was preparing to pressure wash the trans and was look at the transmission wiring harness the goes into the transmission. It is a harness that is held in place with a threaded torx bolt in the center. Not a push on like you typically see. I guess my question would be can i use the internal trans harness from a 4L60E in place of the one on the trans now? Or do i have to get a new internal harness?
