I've set this tune up and I'm extremely happy with it.
I would like some feed back. I'm 21 so you can imagine that i love the firm shifts. but i don't know what the extremes are of the 6l90 as far as shift times and pressures and everything else really.
-how fast is too fast ? (shift times)
-how low can the shift transitions be set? (initial & final)
-what is recommended for the desired output torque factor tables?
-are my shift pressures to high ?
-are oncoming/off going pressure presets OK ?
-Oncoming volume tables too high ?
-max/min adapt volumes ok?
-TCC pressure apply ramp too aggressive?
-are there any unseen dangers such as shift overlap with this tune ?
the more feedback the better !
I'd like to add that
I live in Miami, FL and so far the hottest my trans has gotten with this set up is 179* after a few runs.
so i don't think there is any unwanted friction.
please review !!
thanks in advance
