Gearstar Performance Transmissions is one of the first companies to manufacture high performance automatic transmissions to the specifications of the engines, horsepower and torque output, rear gear ratio, circumference of the rear wheel and tire, the weight of the vehicle, and the application which it is to serve. We are employee owned by people that have a true passion for what they do.

Gearstar Performance Transmissions manufactures world-class, high-performance automatic transmissions built to exact specifications. From start to finish, they are built by the industry's top expert technicians. We are employee owned by people that have a true passion for what they do, using only the best US made performance parts available. Each transmission is custom re-manufactured, built to specs - That means we don't have pre-built transmissions sitting on our shelves. In order to maintain consistency and quality during the building process, each and every transmission is handled by a single builder from start to finish. And every single transmission is put through rigorous qualification and inspection process, along with the fact that each transmission and converter are extensively dyno-tested as a package equivalent of 100 mph on the street where we check hydraulic pressures, temperatures, shift quality, converter stall and lock-up. We make sure each all shift points are at the correct RPM before engaging into the next gear. When you receive your transmission and converter package, you can be sure it is functioning perfectly, because we make sure it's perfect before it leaves our shop. Whether it is a Turbo 350 going behind a mild small block or a 4L85E built for a C5R 440 blown LSX, the same expert technicians will be working on either package. At Gearstar Performance Transmissions, we approach each project as if it was going into one of our own personal vehicles.

Busy Day at Gearstar, grateful for the trust our customers place in us, please be patient, unfortunately this is not a process that can be rushed, 8-9 hours is average build time for a transmission, another 2-3 of DYNO time.

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!
