https://www.camaro6.com/forums/showp...&postcount=124 In my case, getting fueling sorted first, then TC and transmission tune. Id be doing your trans suggestions now if i didnt need it unlocked first. Want to get fuel and a follow up 1/4 mile run in beforw the track closes, then i can tear back into things. |

Exactly one of the reasons I got rid of my 2019 Colorado Z71...That 8L45 trans/torque convertor are $hit...Felt like like I hit a brick wall one day it was so bad. Hope you can get the issue fixed resolved. Gm already has a multi state Class Action Lawsuit against them for the 8L45 & $hit converter.

In my very limited experience of two data points (one 8L45 and one 8L90), the 8L90 is clearly better, it has been since day 1 even before my shudder prevention measures. No clunky P-> R shift, no clunky initial 1->2 shift in the morning, no lurch on the 3->1 downshift when going uphill, which my 8L45 all exhibited to a varying extent.
Now that the 8L90 is tuned and the car has no AFM anymore, it's a perfect trans, only the handling of user input (paddles, stick) is slow, but I don't think that's the transmission's fault, the shifts themselves are quick and authoritative in sport/track with more throttle input, and buttery smooth in tour (aka grandma aka fuel "saver") mode.
