can I get the 4l60e table pretty please
you can also adjust the trans line pressure alittle I think max is set to 96psi. Try setting it to 96 and see if she shifts then. You can always go back and play with it but it could be your trans...
not good no need maybe if you only traverse hills and mountains maybe but its shifting with it locked up is no good for longevity.It would work but for how long. I myself only have lookup in forth...
shift time is the desired time it should shift the pressure controls it but it should adjust the pressure to try and hit that desired shift time since its adaptive it should actually learn and use...
I tuned a friends truck and set up his efans to work but he had a bad battery and we used a jumpbox to power it in order to program it. Fans were working correctly and everything was fine. Then his...
no I wish it was that easy theres a bunch of formulas that you got to factor in gear ratio/diameter of the tire whole bunch of crap... tire diameter x 63360 feet in a mile=revs per mile

Tire Size(s)
235/75R16 = 29.9x9.3R16
29.9-2.23%=29.23 which is what matches stock calculated tire size
255/70R16 = 30.1x10R16
30.1-2.23%=29.42
30.08-2.23%=29.40

check your shift times most likely it will explain why 3>4 shift is so fast if its anything like 2001+ 4l60e its zero'd out
I would also check your 3>4 shift id compare both that and the torque converter lock up speeds and make sure lock up speeds are a little higher for corresponding throttle position cells. If...
