Toyota Supra 2020+ A90/A91
Drag 750 Build Service Includes:
The Drag 750 8HP51 upgrade service is very affordable and perfect for someone who is looking to run low 9’s consistently and many times over without worrying about transmission slip. This Build Service is rated for 750ftlbs.
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 1st, 2nd, 5th, and 6th. This is why a stock transmission will slip in 5th or 6th 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, including A and B, which we do not upgrade, 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 transmission in our shop Supra. Every transmission gets driven on to ensure it is performing correctly.
** Note that in most cases, you will have to reset adaptation values in your TCM with a transmission build **
