Trusted By the best. We have built hundreds of Transmissions & Converter Packages for most of major players in our industry.

Our pals over at STA-BIL brand Fuel Stabilizer recently sent their 60th Anniversary commemorative 1958 Apache over to Mecum Auctions in Indy in July, with all proceeds from the auction went to the amazing folks at Curing Kids Cancer.

In case you missed it, back in 2018 HOT ROD built this beauty for the Week to Wicked series! The STA-BIL crew brought this ride along to the 2018 and 2019 Power Tours, and cruised every mile in style. With a 6.2L Gandrud Chevrolet Performance LS3 under the hood linked up to a Gearstar Performance Transmissions 4L70E, gusto was no issue. And with a Classic Performance Products, Inc front end and Vintage Air, Inc. in the cab, the crew stayed comfy too. Tap the link to see a full recap of that week! ➡️ https://bit.ly/3fpttON

Zack
Really appreciate all your time and input. I attached 4 photos highlighting 2000 hours I have put into this build and the reason why my current trans is such a disappointment. With your help I feel confident that there is light at the end of the tunnel. $3000 for a transmission that feels like crap eats at me like cancer.

Respectfully,
J Riess

Finally got on the road. Wow - tight shifts, works great with Holley Dominator. Thanks!
Finally got the project on the road - trans works great. Thanks guys.
Took my 572 cu in powered 32 Roadster out on the highway today with my Gearstar 4L85E and 9 " Winters. Dropped into over drive and I was cruising at about 70-75 mph running around 2200 rpm. AWESOME TRANS! Thanks Zach!
Took my 572 cu in 32 roadster out onto the highway with my 4L85E. Dropped in overdrive and was cruising 70-75 mph at about 2200 rpm. AWESOME TRANS!!! Thank you Zack!
After I placed my order 5 weeks ago, I picked up my brand new TH700R4 Lvl. II at Frankfurt Airport today! Can't wait for winter to come to install it in my car! Zack, thanks a lot for your help, your patience and your support!
Tomahawk was put thru 2 days of hot weather, racing this past weekend at UMI Motorsports Park. Zach and the crew at Gearstar built me a bullet proof Stage 4, 200r4, reversed, manual valve body, YANK converter, Monster! What a great job guys! 16 year customer!
how does the core return process work?
Ahh, shining up the link between power and application...
Thanks Zack for allowing me to have so much trouble free fun with my 632ci engine using your 4L85E Level 4 transmission. Made my year in 2018!
Quick question. How cold is too cold when it comes to transmission fluid temp? I've heard normal operating range is 175-225 but is it bad to run from say 135-160?
Is there anything you guys can do with a roto hydro matic 3 speed automatic transmission from a 1964 Oldsmobile Dynamic 88? I've heard their not worth the rebuild, but I want to keep the original equipment. I plan on adding a little more power to the 394 but not much, I just want a reliable cruiser.
GearStar to the rescue! 4L85E PRO with transbrake!
