Want to take the trans a step further? Designed in-house and made from 4340 steel, our C Hub is available for the Drag 850 package.

The upgrade service is very affordable and perfect for a mildly to moderately modified Supra / BMW.

In this build we address the three main weak points of this transmission, Clutch E, C and D. Clutches E and C are small and take a lot of the torque in 1^st, 2^nd, 5^th, and 6^th. This is why a stock transmission will slip in 5^th or 6^th when overpowered. We upgrade the frictions and steels in both these clutches but also add two plates to the stock clutch count. The D clutch gets a similar treatment but with only one extra plate. All clutches are set to specific tolerances to ensure they work properly and tighten up the shifts even more than a stock transmission.

We also fully test each 8hp51 transmission in our shop Supra. Every transmission gets driven on to ensure it is performing correctly.

Core exchanges are available for the 8HP51. Our transmission cores do NOT ship with a valve body. You will need to swap your VB over to the new transmission prior to installation.

** Note that in most cases, you will have to reset adaptation values in your TCM with a transmission build **
