Once the transmission case has been thoroughly prepped, reassembly begins with installing only the best parts available. For instance, if the transmission being built is a General Motors product, the planetary used will be a genuine GM unit sourced from ACDelco for $400 instead of a Chinese copy that sells for $40. By the time a Gear Star blueprinted transmission is completed, it will contain only the best brands. The clutch packs will be from Alto, the world's largest producer of automatic transmission parts (located in Atmore, Alabama), while the torque-converter will be from Yank Racing of Reno, Nevada. On the outside, external parts such as custom remote filler/dipsticks, high-tech kick-down kits, and shifters are sourced from Lokar Performance Products of Knoxville, Tennessee. To handle the increased cooling demands generated by an automatic transmission subjected to extreme use, Gear Star offers two SoCal companies' products: transmission coolers from Hayden (of Corona, California) and cast aluminum transmission pans from PML (of Inglewood, California).

Although it's true that a custom-built Gear Star transmission can cost thousands of dollars, it's interesting to note that a Gear Star Turbo 350 can be bought for only $895 ... which is one heck of a good deal considering that it will be assembled by the same builders who do the high-end transmissions and that the same top-quality brands are included.
