Performance Transmissions


The Modesto transmission shop you can rely on.


The 700R4 transmission is one of the most popular transmissions used in hot rod applications today. Hot rod enthusiasts like it as it has a low first gear and an overdrive gear. It drops the rpms approximately  600 rpms in high gear vs a turbo 350 or 400 3speed transmission.  It was used from 1982 to 1992 in a wide variety of vehicles. The best year to use for performance is 1988 up. The stock transmission had many issues and we were seeing them fail at low mileage. Some updates were done over the years from the factory to help them last but most were not addressed. However there are several updates available aftermarket that make them perform and last much better.

We have perfected this transmission over the years and have a unique method of making them perform at their best in a wide variety of vehicles. We have done conversions on many different vehicles, from 1800 lb street rods to 6,000 lb trucks with 3:08 gears to  4:11 gears.  When you order a transmission from us, we will pull one off the shelf and customize it to your specific vehicle and when it is installed, we will adjust it for free. This is the difference between enjoying your 700R4 transmission and being frustrated with it. “transmission not set up for your vehicle = bad“,  ” transmission set up for your specific vehicle = good” Visit our site at https://www.ctttransmissions.com/high-performance.html
