Oct 2016: We are starting to see some 8L90 transmissions coming in. While we are still in the developing stages on our clutch and hard part upgrades, we are currently offering a "Freshen" service with some custom clutch pack adjustments to the 2-3-4-6-8 and the 4-5-6-7-8 clutch packs, (these are the ones we are seeing getting hurt first). Also we can provide TCM tuning for the 8L90. Call us for more information and pricing! 

Aug 2012: New 6L80 & 6L90 upgrade! We are now using a stronger, new & improved 300m Billet Intermediate Shaft with a modified hub for the "Powerglide Powerpack" 4-5-6 clutch pack! This 8 friction pack uses the much wider Powerglide hp friction for improved holding power & longivity over the conventional 4-5-6 PowerPack. The custom-made 6L80/90 P.G. pressure plates resist coneing & warping and allow us to run higher increased 3-4 shift pressures in the tune for big HP. This is the same basic clutch pack that we use in our racing Powerglide tranny builds that can run all season in a low 8 sec. bracket car!


Jan 12, 2012: Just received from Alto some 2-6 PowerPack proto-types. We'll be testing them now. Alto also has a PowerPack in the works for the 1-2-3-4 clutch. We'll keep you posted!

Jan 2, 2012:  Over 400 passes on Century 6L80!

Chistopher Martin has now logged 407 hits over the New Year's weekend, (must be nice being able to race year-round in Southern California, huh?).

March 8, 2011: 151 10 sec. passes on Century 6L80!
Christopher Martin (aka thesubfloor) has now logged over 150 1/4 mile hits in his street-driven low 10/high 9 sec Vette! 


Jan 22, 2011: 9.75 @ 139 mph - World's fastest stock eng (bottom end & heads) C6 Corvette w/Century 6L80 automatic!
