2018 Silverado 6.2 8 Speed Shifting Help

[Ruggerfly]

Good Morning,

I've started tuning the transmission to cleanup shifting and slip. So far I've done the TCC Lockout for 1st-6th Gear, helped a lot. Does someone have a base tune for shifting? 1st - 6th still feels a teenager learning a Manual - whatever power i have at the end of a gear the shift puts me out of power and has to ramp back up, plus all shifts are lethargic.


thanks

I would allow lockup in 5th personally. You could post your tune and a log and get more assistance.

5-6th is a good time to lock it up, i added 40 psi more to the tcc over stock pressure, and I don't see any slip on the graphs, its got that nice chugging feeling when loaping down the road at 80mph
