6l90 into 2017 Regular Cab Silverado

Recommended Posts

It's not plug and play. The TCM inside the 6L90e is not programmed to your computer, so it wouldn't ever work.


Just build the 6L80e, put in a better torque converter and tune the transmission. It will handle a lot of power.


You'd be doing the same things to the 6L90e, adding better clutches and parts and a new torque converter.


If you decide to get a different used 6L80e to build or a new unit, both would need to be flashed with a GM tool with your VIN and matching operating systems so both the PCM and TCM jive together.
