Gearstar Performance Transmissions

Had a fantastic experience working with Gearstar Performance from start to finish. Zach, Ryan and team helped me spec out a 4L60E rated for my 383 build in my 92 Camaro. The team was able to produce the transmission with the tail house provision for the torque arm to mount. When we went to install the new Gearstar Transmission it went in perfectly where the 700R4 had previously been mounted without any modifications. With the new transmission installed, my Camaro is going through the gears flawlessly. This was a huge upgrade! Highly recommend Gearstar.

I can’t begin to take ALL of the credit for this 68 Nova of mine, nor would I dare try and take credit for this beast of a transmission; Gear Star 2004r Stage IV. My 427 stroker pushes 580 HP N/A, this transmission isn’t even phased. With a 2800 stall, I’m able to make solid launches! What I truly love about this company is not only the solid transmission, but a solid company that backs their product. Customer service is top notch and very responsive. They are easy to talk to and truly want to help. I’m looking to boost this engine in the future, this transmission has plenty of room to accommodate for the power! If your in the market for a transmission for your hot rod or muscle car, You will not regret going Gear Star

I recently purchased a Chevrolet 4L65E Level 4 Performance Transmission from GearStar for my 1968 Camaro restomod project, pairing it with a 500 HP LS3. GearStar helped me select the ideal Yank converter stall speed basedon my specs, and their technical support was outstanding throughout the process. Any hiccups along the way were quickly resolved. I worked directly with Ryan on many of the details, and I can confidently say this is a very well-built transmission. Initially, I was hesitant about working with an out-of-state company, but that concern quickly faded. GearStar was easy to reach and maintained excellent communication from start to finish. I chose a Holley ECU to control both the engine and transmission, and GearStar was able to configure the transmission ICF based on my setup.

So this is my 2nd Hot Rod(built) transmission from Gearstar. Not only do they build a GREAT transmission, but they have customer service that goes beyond the competition. I had issues with my install because I put in all Holley EFI and had Holley's transmission controller. Ryan at Gear Star took multiple calls and emails to help me figure out MY problem. It wasn't the transmission, was at my end of install. Then at GoodGuys in Columbus we spoke and he new who I was and even gave me a really cool tshirt and talked to me about the truck. So I give these guys a Big 5 Star review and will check with them on all my transmission needs, not just the street rods!

These guys are seriously awesome and have wonderful customer support! I didn't know much about transmissions or my 4l60e going into it but they helped me get the details they needed to build it to my truck. Then I had some troubles with my tuning and aftermarket ecu that was already on my truck, which they also helped me get it tuned correctly and safely. All responses were very timely and very professional! If I'm ever in need of a performance trans again, I'll be coming back. Purchased a Stage 4 4L60E. (I only have a picture of the old one out)
