trans question

[Dfresh]

so I was looking up my rpo codes for my 2012 Sierra specifically the trans the trans code is myc and it says it's a

TRANSMISSION AUTO 6 SPD, HMD, X15R I have never heard of this is this a 4l65e ? Was looking at doing corvette servo upgrade

MYC is the 6L80. No servos on that bad boy. All clutch to clutch operation.

Hmm learn something new everyday is there any upgrades for these trannys ? What I'm trying to fix is the lag from letting off the gas and getting back into throttle it seems to sit there for a second and then it's like it goes into gear hard is this because of torque management ? Can it be changed thru tuning ? I'm completely new to this kind of set up came from a 93 suburban to this and is this like an hd trans or just a med duty trans
