How to Install a Torque Converter on a 4L60E Transmission

by Renee Booker

The torque converter on a General Motors 4L60E automatic transmission is an essential link between the engine and driveline. The torque converter uses fan blades in a sealed case to create a fluid coupling that transfers power from the engine to the transmission. Installation of a torque converter is a simple, step-by-step process that can be completed in under an hour.

Step 1

Use a funnel to fill the torque converter with one quart of automatic transmission fluid.

Step 2

Slide the torque converter onto the input shaft of the transmission. Turn the converter left and right as you push it onto the shaft to make sure the converter engages the lockup shaft, input shaft, and front pump. You should hear three distinct clicks as each is engaged.

Step 3

Install the torque converter to the flywheel bolts, but do not tighten. Be sure to use grade eight bolts.

Step 4

Measure the distance from the flywheel to the converter. The distance should be no less than 1/8 inch and no more than 3/16 inch.

Torque the converter to flywheel bolts to 46 foot-pounds.
