6L90 seems to be shifting harder... Hey guys, the 6L90 in my stock 2010 2500HD 4x4 seems to be shifting harder over time, 1-2 and 2-3 under light to normal acceleration. I bought the truck with 82K in 2015 and have about 120K now and don't tow much but run it through the gears fairly often.
It also acts completely different when the truck is not up to operating temperature, ~210 on the gauge. If I get on the road when the gauges between 160-180 the shifts are obviously different than at 210.
Are changing shifts a symptom of a problem?
