Looking for a new/used ZF 8HP90 transmission out of a Redeye preferably. My trans blew on the dyno last week... Any help is beyond appreciated.

Here's some:

We upgrade your 8HP9X transmission built to our 8HP9X “Super MAD MAX Series.” Our 8HP9X “MAD MAX Series” transmission packs a punch and is built featuring Raybestos frictions. Kolene treated steels with our proprietary assembly techniques and upgraded Super Super “E” Drum with added custom steels to support the Super “E” Drum, which leaves it second to none. It comes pre-flashed to the latest factory software and can includes transmission tuning to ensure a long, happy life for an added fee. (Rated at 1500rwhp )


Our design is a two-piece bolt together. It allows you or your shop to change stall speeds and clutch configurations without ever sending it back to us. You buy one converter and that’s it. After that you can handle your own refreshes, stall changes and clutch changes! Our converter is almost 15% lighter than a factory converter or the Demon converter upgrade. This weight savings is instantly apparent as soon as you go WOT. Your engine will spin up so much quicker due to the decrease in rotating mass!


Often-neglected lower-temp thermostat for the transmission. Consider upgrading the cooler to larger capacity, also.

Were you shifting when the failure happened or just steady running in 6th (direct drive, the Official Gear of the Dynamometer?)

At what speed did it let go?…its looking more and more like the stock shells have a high speed threshold, there was one cat that I know of that blew the shells on the street and the fluid caught fire on the exhaust but it’s more common on dyno’s…multiple load off lift foots seems to start the launch sequence..eventually the tuners will come up with a cut off point when testing to avoid a messy clean up
