Using BlueCat to set the shift and TCC schedule on a stock Silverado/6l80 combo. TC is unlocked during shifts, raised oncoming pressures, and lowered WOT shift time to 3.4xx. First WOT pull and 1>2 was violent and may have slipped. Definitely had a rowboat feel, and the log isn't pretty. The shift time seems modest compared to others on the forum, so should I increase the pressures a little more? The log shows 2k rpm of trans slippage near the top of first, but it accelerated strongly the entire time. Stock truck and TM hasn't been touched. Ideas?
