According to the Great Smoky Mountains National Park this weekend will be near peak for fall foliage. Beyond a picture perfect location to take your favorite classic, this weekend will be packed with activities: autocross, "Share the Ride" in the passenger seat of two brand new Mustangs on the autocross track, a car show, and finger lickin' good BBQ Saturday night all within blocks of the greatest tourist destinations in the Smokies!
Coming Soon...
Ready to get in your last hoorah's before car show season winds to a close? You can find us at a variety of shows this fall including:

* Holley LS Fest in Bowling Green September 8-10th

Find registration information and the websites to all of these shows on our Upcoming Shows page.
On a budget? We have a solution!
Start saving towards your transmission on the 10-10-10 plan and hit the highway in overdrive next summer! It's a great way to save.

Our 10-10-10 plan is very flexible. By design, you'd pay 10% down and then 10% of the remainder for the next 10 months, 11 months of payments. However, if you wanted to pay it off early or divide your payments into 3 equal payments or the like, all you'd have to do is ask your salesperson. It's very likely they'll be willing to work with you to save for your transmission or adhere to your build schedule.

Do you know your TREMEC 6-Speeds?

We get phone calls almost daily from customers who purchased a T-56 used out of a junkyard or on the internet and they want to purchase a kit from us to swap out their original 4 speed with this new (to them) 6 speed. The problem is, we can't help them. Why not? Because it turns out these are two very different transmissions. Learn more on our website.
Customer Testimonials
Barry's 1979 Vette is automatically better than the rest!

Barry's 1979 Corvette has a ZZ383 Deluxe engine with 450 HP. He considered going with a 700R4, that is until he saw our website! He says our SST A41 4-Speed Automatic PerfectFit™ Kit works very well in his Vette. We're glad he's happy with his decision to go with our more advanced 4L60E based A41.
Klaus's 66 Chevelle SS 396 Convertible is TREMEC Equipped!

Some Chevelle owners cringe at the thought they may have to modify their transmission tunnel to install the TREMEC TKO 5-Speed. However, with a factory appearance and superior performance, the TREMEC TKO 5-Speed PerfectFit™ Kit from SST is a great choice for the Chevelle. Klaus's Chevelle has 360 HP and a new TREMEC TKO-600 5-Speed PerfectFit™ Kit!
Doug's 1961 Ford Starliner with a PerfectFit™ TREMEC TKO 500
