Where do I go next? what am I missing?
5.3, 4l60e, np241 transfer case with 8k vss
I put a junkyard motor and trans in a buggy I built. I had the trans rebuilt by a trusted builder(stock). No matter what i try i cant get this thing to shift to 3rd. When test driving the scanner shows it commanding 3rd gear but then has a shift time error of 6.1 seconds. is there anything else i can check before sending this transmission back to the builder? Here is a list of what I have tried and the outcomes. tune and log attached. Any input is greatly appreciated!
1. Remove tune and rewrite back to stock.
2. Use bluecats software for gear and tire change( speed is reading correct in scanner)
3. Used scanner while engine off to control both 1-2 and 2-3 solenoids ( you can here both click so i assume wiring is good)
