About the 700r4 & Common Problems

700r4_transmission

The GM 700r4 is a 4-speed automatic transmission with overdrive. It was introduced in the early 1980’s, as way to make their V8 powered cars and trucks more efficient. In a world filled with rising gas prices, the General needed to keep its product line relevant.

Adding a 4th overdrive gear allowed them to make their sports cars and pickup trucks more affordable to drive. The 700r4 transmission replaced the 3-speed TH350, and became a popular upgrade for older rear wheel drive GM vehicles.

Broken Input Shaft

Overheating

Another common issue with the 700r4 is overheating. Given the high power output, and extreme use that most vehicles equipped with this transmission see, overheating is fairly easy. As the ATF temperature rises, significant internal damage can start to occur. To avoid this problem, simply install an auxiliary transmission cooler.

3-4 Clutch Pack Failure

Slipping between 3rd-4th gears can signal a problem with the clutch pack that engages those gears. Overheating can weaken the metal used to make the 700r4 3-4 clutch pack discs. If this happens, the ends can shear off, and you’ll eventually have a serious problem.

Warped Valve Body

Due to overheating, the valve body can become warped, which can significantly hamper gear changes. If this happens, you’ll be on the hook for an expensive repair.

Stuck Governor

700r4 vs 4L60 – Are they the same?

In 1990, GM changed the name of the 700r4 transmission to 4L60, which stood for 4-speed Longitudinal 6,000 lb gross vehicle weight rating (GVWR). For 1993, the hydraulic shifting system was replaced with electronic controls (4L60E). A Vehicle Speed Sensor told the engine computer how fast the vehicle was going, that way it could decide when to change gears. Shifts were then executed by sending a signal to the appropriate shift solenoid.
