Hello All,
First time needing help but this is killing me.Long story but will try and condense. Helping a friend swap a 6.0 and 4L80E from a 2003 into a 2006 4.8 4L60E Truck. Mechanically the swap was all good. He did the trans harness adapter for Amazon? Think it does the pin swap. Also did the front speed sensor harness to PCM. I went over and did a segment swap with same OS and did a Write Entire. Changed the tables and changed to 6.0l. Didn't use it right away, still needed a drive shaft. So he started it and it was smooth he said Shifted like butter. He even pulled a trailer with it and had no problems but was lacking some power in mid and WOT. So he came over and I did a PE change and raised the timing a bit. Also removed VATS because had one leave me before. Went to write entire and it Bricked!
After getting a different PCM and flashing the same file and segments it is pulling gobs of timing in torque management. It also has a harsh 1-2 where as it didn't before, Also the hot transmission message and goes to hot mode?
Got another pcm with a different OS and did a segment swap. And left everything as found but PE and still has same problems except have not seen hot trans yet but has not been driven far. Attaching file and log. You will notice that it is still a 5.3 as didn't want to change a lot yet.
I am logging input speed on trans and reads 0? Don't know if this pid is valid for the setup or maybe it is the problem. It does have fluid in the trans connector and is being changed.
Any help is greatly appreciated.
