Which GM transmissions does this cover?
The RWD 6-speeds and the FWD / AWD 6-speeds. On the RWD side: 6L45 (Cadillac CTS 3.6 RWD, ATS 2.0T / 2.5) and 6L50 (Camaro V6, CTS / CTS Coupe, SRX, STS, and 2012-2016 Colorado / Canyon), plus 6L80 (Silverado / Sierra 1500, Tahoe, Suburban, Yukon, Avalanche, Camaro SS, Pontiac G8, Chevrolet SS, CTS-V) and 6L90 (Silverado / Sierra 2500HD and 3500HD, Suburban 2500, Yukon XL 2500, Escalade, Express / Savana).

Is this the same as the 8-speed T87A service?
No. The T87A is the 8-speed Global A TCM (8L45 / 8L90 / 10L80-family era) and it is a separate box with a different clone / unlock procedure — that is our dedicated GM T87A service. This listing is specifically the 6-speed TEHCM built into the valve body / solenoid pack. If you are not sure which you have, send the VIN and we will point you to the right service.
