The 8L90-E transmission is adapted from the production-based version, features a 664 lb-ft torque limit and is available for either the LT1 or LT4 crate engine option. A slip-yoke design is for use with the LT1 and a fixed-yoke design is to be used with the LT4.

According to Chevrolet Performance, the 8L90-E’s numerically high 4.56 first-gear ratio offers strong take-off performance while a wide 7.0:1 overall ratio helps optimize cruising efficiency.   

Other features include four gearsets for greater efficiency, five clutches (two brake and three rotating), world-class upshift speeds and friction-reducing features, including synthetic fluid. A torque converter, controller and harness are included.

You can download a hi-res version this week’s wallpaper above, or check out our Instagram story on @theblockdotcom.

This transmission is also part of the Shift into Summer promotion this quarter, in which all Chevrolet Performance transmissions are eligible for a $200 mail-in rebate*. In addition, a $50 mail-in rebate is available on all Chevrolet Performance transmission controllers and torque converters. Customers simply need to purchase the part from an authorized Chevrolet Performance dealer by June 30.

They can then mail in the rebate form or complete the process online at www.mycertifiedservicerebates.com.
