6R80 Performance Transmission Rebuild


Circle D Transmission can transform your 6R80 into a performance beast. Our custom modifications set us apart from the competition and have paved the way for us as the industry leader in the 6R80. The majority of the vehicles that we upgrade or rebuild with a 6R80 transmission have between 600 - 1000 RWHP. We have been successful with vehicles that have up to 1200 RWHP. Below is information about the transformation.

CDT 6R80 bench rebuild includes labor and all parts itemized below. You will need to ship your transmission to us for the rebuild.

Transmission Tuning We do not supply a TCM or ECM tune.

Flushing Cooler & Lines We cannot stress enough the importance of flushing the transmission cooler(s) and lines, even if they are new. We recommend using a Hot Flush Machine or something comparable.

Auxiliary Cooler You need to install a stacked plate auxiliary transmission cooler, rated for 25,000 GVW. The ideal operating temperature for this transmission is 180°or less. These transmissions have a tendency to run very hot – the cooler will lower operating temperature and recovery time which in turn will extend the life of your transmission
