Need help with trans problems
Hello,
i just installed a 6.0/4l60e into an 01 s10 and im using the pcm that came with the 6.0. The pcm was for an 4l80e but i changed the tune to an 60e and all the tables that are in the trans section to an 60e. Everything seems to work fine when at part throttle but when i go WOT it doesnt shift. I just goes to the redline to were the fuel cuts and if i release the pedal for about 2 seconds until it takes the second gear i can go WOT again and it does the same again when i get to the third gear. Is there any way i can even use this pcm or do i need to get a 5.3/4l60e pcm? Oh and i used a harness that came from an 5.3/4l60e so i dont think i need to change the pins in the transmission connector unless this pcm has different pins than a 5.3 one. Here is the current tune and also a log. The first to second gear actually did shift but at some where 6000 rpm even if the tune is set at 5600 rpm. The second-third gear didnt shift while staying at WOT only if i realese the pedal.

Actually the pcm comes from a 2001 2500HD Silverado 6.0/4l80e. The tune i posted is the stock tune besides changed from 80e to 60e and some other minor changes but didnt change the OS number. I know "12202088" is from an ls1 but some trucks also have the same OS number.

The tune is a 2500HD 80e converted to an 60e. Hp tuners is gonna do a segment swap for me now and then i think it should work. I have a few 5.3/4l60e pcm's laying around i could use but i wanted to use this one because i already spend the credits on it. And of course maybe i could learn something i could use in the future.
