ok so heres my dilemma:
-with shifter in "D" or overdrive and i have my TCC unlock at 43% in 3rd or 4th
-say i go at a steady 20% throttle and TCC locks at 25mph and 4th shifts in at 30mph where the TCC locks at 38mph in 4th
-running 3.73s and a 3200stall with built trans
going from a stop or slow roll and shifting into 3rd at like 21mph i then have the TCC engage but then unlocks upon shifting into 4th gear and it'll lock again when it reaches 38mph.
is this normal? i looked at alot of other's tunes and noticed that a majority of ppl have both 3rd and 4th TCC enage at the same mph, for example 40mph. i never had an issue running this in a fwd 4T65E for the tcc to lock in 3rd and remain locked going into 4th. i can upload a copy of my bin file fwiw.
