Get Out the Checkered Flag!
It was a tough race, our pit crew is drenched in sweat, but we're finally back to our normal ship times! Victory lap! TREMECs are in stock and on the shelf and thanks to the hard work and long hours of our dedicated staff, we've pushed the TREMECs through our production process at an expedited rate and shortened our turn around time to 2-3 business days as usual!

MAZDA RX7
We're drifting our way into the imports market. In the R&D shop, we have a 1993 Mazda RX7 that makes 850 hp at the rear wheels thanks to the built 13B rotary engine with a massive Garrett turbo. We're putting a TREMEC 6-Speed in this one with our STX Shifter. We'll share videos and photos once the kit is finished and in stock!
Tech Corner
Fluid Faux Pas
When you get your kit and installation manual, on the very last page you will find a list of acceptable fluids for use in your transmission. It is VERY IMPORTANT that you only use these fluids. Other fluids will void your warranty and for good reason.

We recently had a TREMEC transmission come back for shifting troubles. The customer had used an unapproved fluid. The fluid was too thick, which slowed down the synchronization and caused gear clash which damaged the clutching teeth of the gears and synchronizers. Unapproved fluids can also react with and cause damage to the brass blocker rings.

So, even if they come in flashy colors, cost much more, promise you the world... don't fall for them! Use the approved fluids and your transmission will shift smoothly for years to come.
Customer Testimonials
Cover Cars - MOPAR Madness!
Don loves Mopars. He's purchased a couple of transmissions from us so far and plans to purchase more. His cars are beautiful and you can see them and under their hoods too on our website.

I drove from Florida to upstate New York a few years ago and cruised all the way up & all the way back to Florida with 24.2 mpg average on over a 4000 miles I put on the car on this trip--I got pulled over 4 times & all they wanted was to look at the car--This was my 1st conversion before kits were available--but it is violently fast & quick--its where I became addicted to these trannys--thanks for making kits--its a lot easier than fabricating parts.
