The G101A is the latest generation of our 4 speed drag racing transmission. The G101A can be built as either a clutchless or clutch assisted unit. The biggest difference from the previous generation G101 is that the new G101A has a center bearing support that helps keeps the shafts from spreadingunder high loads. This greatly increases horsepower capability and also prolongs the life of the sliders and faceplates. The G101 will take approximately 1000 HP, depending on the application.

Also, when built as a clutchless transmission, the G101A DOES NOT USE springs between the sliders, which had a tendency to come off in the previous design G101 due to the larger ratio drops in a 4 speed transmission as compared to a 5 speed.  The G101A is a great alternative to a 5 speed when looking at cost savings in either a drag race transmission or road racing transmission. The G101A has also been proven to be a very effective drift transmission where center-shift transmissions are not necessary. Also, this transmission has been approved for various spec-type classes worldwide.
