There was also a major upgrade to its internal components, such as the pump housing and ring gear. To, however, improve the reliability of the gearbox, the input shaft was increased to 30 after 1987. Earlier versions utilized 27 input shafts known to break due to the inability to withstand much torque. The 700R4 transmission was manufactured by general motors in 1982 and had since had many updates to improve it. It’s specially built for heavy-duty 4×4 trucks and is regarded one of the best off-road transmissions ever. This K case 700R4 is stronger and utilizes a thicker transfer case. The stamped K is even visible on the 700R4 transmission diagram. It has another version called the K case 700R4 and was particularly differentiated from the ordinary one by stamping K on the transmission case. It is built with cast iron, which makes up for its toughness, yet lightweight with its transfer case housing 16 bolts. Thus, allowing large and performance cars more affordable to use since they now consume less fuel. The 700R4 featured an overdrive 4th gear which is responsible for the 30% increase in fuel efficiency compared to the TH350. Without transmission fluid, the 700R4 weighs 170 pounds and is about 23.5 inches long.

The 700R4 transmission fluid capacity tops at about 11 quarts. It uses four forward gears and one reverse gear and works only with recommended transmission fluid known as the DEXRON VI. And also became a better option for older General Motors utilizing the rear-wheel drive. And came a replacement for the former three-speed TH350 automatic transmission. The 700R4, otherwise called the Turbo-Hydramatic transmission, is a 4-speed hydraulically operated automatic transmission built for sports cars and bigger trucks and vehicles.

It became very popular because of its ability to boost fuel economy no wonder it became a good choice for performance vehicles and big trucks that usually will consume more fuel.Īside from being fuel-efficient, it also performs with so much practicality, giving drivers the push they need. One of the most widely used automatic transmissions, especially among older cars, is the 700R4 transmission made by General Motors.
