Master Kit with Steels, GM 6L90 2007-Up

Transtar Part Number: 104006B

The 6L90 is the big brother to the 6L80. It is a heavy duty version of the 6L80. The differences are subtle, but enough to require different kits. The 6L90 has more clutches in each clutch pack, a larger rear seal, and a different configuration pan gasket. The 6L90 is used in 2007-Up GM 2500 and 3500 series trucks. Also available is 104004B master kit without steels.
