Looking for a complete solution for your 8L90 transmission? Have you reached the power level to start thinking about your transmission or is your transmission already flaring into gears? A lot of guys talk a good game, but our builder backs it up with solid performance and the best materials along with custom building and tuning to come up with the perfect solution for your performance needs.
We're ready to turn your 8L90 into a performance beast. The majority of the vehicles that we upgrade or rebuild with a 8L90 transmission have between 8-1200 RWHP. There are three options to choose from: you can either ship your transmission to us: Bench Package or you can transport your vehicle to us: Vehicle Package.
We highly recommend the Circle D built triple disc billet converter with these as well!
A Custom tune package is a must for this trans and makes a huge difference in the performance. This is $300 additional for the starter tune and will need dialed in for the MPH shift speeds in real time.
