I had a great experience working with gear from start to finish . It’s nice when someone answers the phone if you have some questions or they will call you back promptly. It’s hard to get good Customer service these days . I do believe that good customer service creates more business as it creates better reviews. I will be going to gear Star for my next project. Thanks Gear Star for being a five star Company.

Absolutely Worth it. We have installed 5 of the Gearstar Transmissions mostly 4l65e and 4r70w options. These have been in classic muscle cars and trucks, they have been helpful at every stage of the process and even once when we screwed something up they have been gracious enough to handle it for us. You might be able to find cheaper options but you won't find anything or Anyone better than Gearstar.

I had a custom LS3 swap build with my 1969 AMC Rambler Rogue that required a transmission to handle the 600hp output for street and strip, while dealing with the Las Vegas summer heat. Once I reached out to Gearstar through their website, I was immediately connected with Ryan who helped me assess the best options for my specific situation. Once I settled on the 4L80E Phase three transmission and the matching converter, the transaction and communication was first class, Not only did they build the transmission to my specs, but they also sent me updated communication during the process as well as live videos of my transmission being dyno tested. Shipping was prompt and the transmission was packed with care. Ryan addressed my follow up questions once I received the transmission and his communication was flawless. I now have over 1500 trouble-free miles on the Rambler and it has been on Power Tour and ran hard at the dragstrip with no issues. I am going back to Gearstar when I start my next project!

This is a great company to purchase a performance transmission from. I purchased a 4L65e stage 4 for my 1979 Camaro. I had a few questions and Ryan was there every step of the way from purchase to after installation! Since this was my first time dealing with an electronic transmission he pointed me in the right direction with the correct transmission control unit. After installation Ryan was still there to help me fine tune torque converter lock up and shift firmness.
This company will return calls and answers the phone. I love it!!
Oh and the transmission came packaged perfect without issues.

Ordered a 4L80e with all the goodies. 3 disc billet converter US shift controller, etc. Project was a NA 598cid chevy big block (794hp, 758ft-lbs, dyno) Ford 9in rear, etc, etc. Told them I never wanted to worry about trans and to built it for 1000hp and 1000 ft-lbs. Ryan went out of his way to work with me and understand my application, stall requirements, etc. They even included a holley tps to match my 1250 dominator! When ever I had an install question Ryan was quick to get right back to me with answers.
I spent much more effort procuring the 6L90 for my 1200hp Trail Blazer SS. Wish I had found gearstar for that project! The gear box is fine, but the experience was much less pleasant.
This is NOT a paid advertisement, I just really like these guys! Even got a video of MY trans on their dyno for the run-in and test.

In 2009 I ordered a Gearstar 200 4R transmission for my old 1959 Chevy Apache truck. Well after two different builds and around 50,000 miles. I have no issues with the strong 200 4R trans. I did call several days ago and asked a question on the overdrive switch and Ryan answered with no problem.

I'm beyond pleased with the Gearstar Performance Transmissions Level IV Pro Series 4L80E automatic transmission and Yank Performance Converters 3,400 stall torque converter that we installed in my 1,200hp 1986 Ford Mustang LX. The package is stout, and it performs exactly how I need it to for heavy street/strip use. With this drivetrain upgrade, which includes a Holley EFI Terminator X Max ECU to control the transmission, my Mustang now has the best street drivability it has ever had, and overdrive for freeway compliance. I endorse Zack Farah and Gearstar Performance Converters. Everything they've done for me has been top notch.

Quite possibly the best customer service I've ever experienced. Ryan and his team are incredible. They take so much care to answer your questions and discuss your personal needs. They truly appreciate your business and I appreciate their service & expertise.

Gearstar is beyond first rate. They've totally supported their product, even after the warranty expired. Larry was superlative.

Top Notch company! The whole process start to finish was a great experience from Zack on the front end helping me put together the best fit for my vehicle which is a 1967 Buick Rivera a bit of an oddball with a built 600+horsepower motor and about the same torque. Larry was on the technical support end, who had actually built my transmission himself and knew it top to bottom and could answer any questions I had with it, without any bit of hesitation. I would recommend Gearstar to anyone who wants a quality product and experience, it was refreshing to deal with people who care and are still running a quality business. I say this as a company owner myself. Jesse H.

I have known Zach for 30 years. There is not a more professional businessman in the area. If you need a high performance transmission built this is the place to go. Highly recommend

I cannot say enough about this transmission, it exceeded all of my expectations. It performs better than I thought it would. This is by far the best transmission I have ever owned and operated.

Absolutely the best in the business! Zack and his guys knocked it out of the park with my 24 Silverado 2500 HD
