TM SHIFTER GM 700-R4 BLACK 16' BENC

GM’s venerable overdrive automatic was introduced in 1982 and has been bravely serving ever since in everything from trucks and utility vans to Caprice police cars, Corvettes, and Camaros, not to mention about a zillion street rods and classics that have had one swapped in. In the modern age of transmissions with a zillion forward gears, it’s not unreasonable to wonder how many gears does a 700R4 have? The correct answer is four forward gears, and in the 80’s, just the addition of that overdriven fourth was pretty revolutionary. These transmission were, and still are, a great way to add an overdrive to increase the efficiency of a thirsty V8. In the forty-some years since its debut, we’ve learned a lot about these transmissions, both good and bad. Here’s a quick overview of the trusty old 4-speed.
