700R4 Transmission

Additional Information

The 700R4 transmission, also known as the GM 4L60 in later versions, is a four-speed automatic transmission produced by General Motors (GM). Designed as a replacement for the TH350, it features an aluminum case, a lock-up torque converter, and a TV (Throttle Valve) cable for shift control.

Fuel efficiency is improved by its 3.06:1 first gear ratio and 0.70:1 overdrive. It can handle off-roading and towing with its hydraulic lockup torque converter. A hydraulic lockup torque converter, cast aluminum case, and TV cable-controlled shifting are included.

The 700R4 is a four-speed automatic transmission that General Motors introduced back in 1982. The reason for its introduction was General Motors to offer improved fuel economy and performance, especially with overdrive. This transmission was widely used in GM vehicles, trucks, and SUVs that are enhanced by the existence of its fourth overdrive gear and lockup torque converter for highway gas mileage. The various applications of these transmissions made it famous from the Chevy Corvette and Camaro as well as full-size trucks. 700R4 later progressed into 4L60 and 4L60E. The 4L60E with its electronic control, provided enhanced precision in shifting. The 700R4 is quite popular for durability and aftermarket support, but if not upgraded accordingly, it can fade under heavy-duty and high-torque applications. Its performance can be enhanced with modifications for high-performance builds, making it a favorite in the aftermarket scene for muscle cars and trucks.

Model History

The 700R4 transmission was introduced by General Motors in 1982. The manual 700R4 replaced the now-aging 3-speed TH350 and let the 4-speed-with-overdrive design earn its immediate fame. Initially used for the Camaro, Corvette, and some trucks, in early transmission models (1982-84) were subject to some reliability problems, especially in high-torque applications. GM improved the transmission’s hydraulics and internal construction to increase durability and performance. By 1987, those improvements paid off, and the transmission was desirable because of its reliability in the light trucks and performance vehicles.  The transmission had been refined enough to gain a reputation for reliability and became a popular choice in both light trucks and performance vehicles.

Stylish Inside and Out

The 700R4 transmission is not only tough in terms of its working, but it also survives the looks test. For outside, the polished or powder-coated cases are a great way to achieve a clean custom look in accordance with some high-end engine bays. Inside, the Pro build gets the transmission precision-machined parts, performance valve body’s work, and upgraded internals that not only increase strength but also provide for smooth and crisp shifting. Whether you’re cruising the streets or hitting the strip, the 700R4 delivers a stylish blend of form and function that stands out in any ride.

 How to Fix 700R4 Transmission Problems?

• Check fluid level and condition – Top off or change if low/burnt.

• Inspect and adjust TV cable – Must be tight at full throttle.

• Identify symptoms – Slipping, no overdrive, no reverse, harsh shifts, etc.

• Clean or replace valve body – Fixes harsh/soft shifting issues.

• Inspect clutches and bands – Rebuild if worn or burned.

• Install transmission cooler – Prevents overheating.

• Test drive and monitor – Check shift points and fluid after.
