Im using hp tuners, i have had more problems outta transmission shifting than anything else on this thing......I talked to jake and it looks like i need to keep a code from popping up (P1810 Code).... My educated guess would be to keep this code from coming up and it should shift outta second when the computer commands it, once i get this problem worked out ill work on better 60' times and hopefully a high 9 second pass or real low 10's..... Just from the time sheets i know a 10 is gonna be easy to get.... My 2-3 shift was supposed to command at 6250 rpm or 84 mph, and it never shifted had to let out of it when it hit the rev limiter
Custom im running a 50mm bov it just sounds like that i guess lol
Just Re looked the logs over and it spiked to 20#'s at the end of first gear then rest of pass was pretty much 10#'s

As I'm sure you know that code is thrown by the pressure switch assy in the trans. I haven't seen this code thrown due to a late shift but anything is possible I guess. What PCM are you using? I might have a few suggestions on trans shift tables that has worked for me in the past..

Its a pcm out of a 2002 hd truck, jake said it would throw the code so i went in an put No error reported for it, my question is will this allow it to shift into 3rd now that its not throwing the code....If u put the truck in drive and do not use the trans brake and do 100% wot down the track it shifts through gears fine... Only time it will not shift is if i Drop gear selector to first, use transbrake, as soon as i let off transbrake i shift it up 3 times to be back in drive and let the computer command it from there on out.....Another thing to i seem to be losing boost in the later rpms so ill prolly set the shift points around 5000 and see how well it will hold the boost up
