    $31 / $0E 4L80 tables

    I'm not quite sure which mask I'm going to use yet. I figure they both will have similar tables to control shift timing and pressure. For now I'd like to stick with $31 and firm up the shifts. I read a couple posts about "shift speed vs altitude gain". I'm still not sure what the final verdict was on that.

    Same me thing goes for enabling PE. I read a few things but didn't quite push me in the right direction.

    oh boy. This isn't my ole 7747 that's for sure!

    don't mess with shift speed vs altitude. Just bump the pressure up.

    Because I was using the older force motor, I had to log the actual pressure and compared it to commanded pressure and modify my force motor tables so they both were close. Then I went ahead and bumped the pressure in the shift tables slightly higher to give me a firmer shift (but no where near harsh).

    What would you say your pressures are at? I made a small increase of 20psi to the "max pressure" and the "pressure vs tps" table. I didn't notice much difference. But I'm waiting on my TransGo kit in the mail so I probably shouldn't be messing with it too much.

    I had a 6.2 turbo diesel with 4L80 using a Quick1 trans controller. That thing was great! The truck had 4.56 years and a Detroit Locker. It would squeak 2nd if I stomped it. I guess I've been kinda looking for that again haha
