Hi everyone.
The truck is approaching 190k miles and the stock L05 and 4L60e are getting tired. I have a complete low mileage 2005 5.3 With ECM and harness left over from another project. Looking for input on swapping this into my truck.
One initial question. Should I rebuild my trans and keep the 427 ECM to control trans only, or go find a late model trans compatible with my LS computer?
look forward to ideas
thanks
