Some awesome testimonials!


I went to the shootout to compete in DSE class, and I made it to final 4. I was #1 in ET's and I was the guy to beat. I ended up snapping the u-joint and yoke in the final 4 eliminations. The transmission shifted awesome.

All runs were done on 93 octane and 50/50 meth. I never missed a single gear. I never have with your transmission.

Another update from the same customer:

Just wanted to let you know how things went in Englishtown this weekend.

Bullseye sent me the new batmowheel s366 to try out for the event. If any of your customers ever ask about it, its awesome. Spool is much faster over the cast ETT wheel, boost recovery is awesome, top end is amazing.

I won the heads up Street 16 class with a 10.5 @ 142mph. My personal best is a 10.3 @ 143, but with 30mph head winds, and a short shift into 2nd gear, I ran a bit slower. I needed some more dial in time, but they went straight to qualifying and eliminations.

Professional pictures from the staff at Etown should be up soon, in which I thanked vendors/sponsors, and I mentioned Jackstransmissions in there, along with Bullseye Turbo, RedJackRacing (sponsor), Racecomponentsinc (sponsor) and others. I'll post it up on your facebook page once I find it and you can use the picture if you like.

I didnt get great videos of the event. All we got is droids and iphones amongst me and my friends, haha. Thanks again for an awesome transmission!



I wanted to say thanks for doing such an excellent job on rebuilding my transfer case! It helped me power my stock block Evo to the world record running a This email address is being protected from spambots. You need JavaScript enabled to view it..

I now have the world's fastest stock block Evo. Everything also came out pretty good with the trans rebuild. Sparktechignitions.net (click the links) put me on their showcase page showing my car and my mod list. I have you guys up there for my transfercase refresh.

Again, thanks for doing such a great job. Your services will be recommended to everyone I know with an Evo. lol



Hey Jack...

Just wanted you to know that after the install of your transmission, I had a grin from ear to ear... I love this transmission and rave about it to everyone. The best money I've spent...




I just wanted to let you know that the transmission you rebuilt for my SCCA Spec 7 RX7 performed flawlessly this race season. It helped me in setting 3 track records, running an undefeated season, and winning the Rocky Mountain Division Series Championship.

Thanks again



This customer used transmission parts from our website to help him build the fastest Galant VR4 in the World:

Well the car did ok a few weeks ago.The tranny shifted great at the track and we took the world record for the Galant VR4 in both ET and MPH.

Here are a few video links:




So I did set the E/T and MPH record for the Galant VR4 with that run, WOT.

And I think I was the 3 fastest trap speed and 4th fastest for a car this weekend.

Thanks a ton for all your help.


Got my Supra home yesterday from Pete Palamara in CastleRock (HighPressure Motorsports). After a winter-long engine & trans build, I can say that my transmission is working perfectly, and most importantly shifts perfectly. I am very happy with the results and would recommend Jack's shop to other Supra owners. The build was done in a very timely manner, and the communication throughout the process was excellent! (Larger motor/head/build review for HPM will be forthcoming in another thread. This shit is tiiiiight!!!)
