Shift RPM in 4LO on 4X4?
I had my truck in 4LO on hardpack and did a standing start wide open throttle and the 1-2 shift was at 3500 RPM and 2-3 was 4000RPM. Does anyone else have any numbers from their trucks. I think this is too low and concerned something is wrong with my truck. Will the Superchip fix this? Thanks in advance.
