How To Install Torque Converter 4l60e

Download Article

The General Motors 4l60e automatic transmission is a very common transmission used in light and medium duty trucks, passenger cars and sports cars.^[ane] Replacing the torque converter in this transmission is unproblematic but it is very mutual for mechanics to incorrectly install information technology. Incorrect installation leads to immediate failure of the fluid pump upon start upwards and requires the transmission to once once more be removed for repairs. This instruction set will evidence how to properly install the torque converter. It tin can also be applied to other transmissions in the "4L" family unit such as the 4L65e.

1

Position the transmission. Position the transmission in a spacious and level area such as an open up garage floor or on a workbench.
2

Remove the torque converter. The original torque converter can be removed by positioning yourself in front of the bellhousing. Concord on to the converter by its sides, primarily at 3 o'clock and 9 o'clock positions. Gently pull it dorsum towards you and slowly rotate in a rocking movement past moving your hands up and downwardly a few inches as if you were turning a steering wheel.

3

Drain the torque converter of old fluid. The torque converter will comprise a few quarts of fluid. Place information technology with the bolt holes face-up in an appropriately sized bucket or drain pan and permit it sit down for well-nigh 30 minutes. The fluid will drain out very slowly.
4

Inspect the input shaft. At present would be a good time to inspect the input shaft for whatsoever damage. If any damages are constitute such as broken or chipped splines, repair before installing the converter and transmission back in vehicle.^[2]

Make full the torque converter to be used. Whether the torque converter yous are using is new or used, it is e'er best to make full it with at least a quart of new fluid before installing. Identify the torque converter face down on a apartment surface and so that the input splines are facing up. The fluid will get in very slowly. Pour in equally much every bit you tin without the fluid running over. One time the fluid drains down, pour in more than and repeat the procedure until y'all have at least a quart in the torque converter.

Install the torque converter. The torque converter will slide onto the input shaft three times, each time seating farther into the bellhousing followed by a "clunk."^[three]
- Start, concur the torque converter horizontally and confront downwardly (commodities holes facing towards the ground) then that the fluid will not drain back out.
- When ready to insert on the input shaft, plow the converter vertically with the commodities holes facing towards you lot. Hold the torque converter past its sides at 3 and 9 o'clock and slide onto the input shaft while slowly rotating it back and along, as in Step two, until you hear the first "clunk."
- Continue to gently push on the torque converter and slowly rotate it dorsum and forth. After a few seconds of this, it volition slide back farther and you lot volition hear a second "clunk." The torque converter is non properly seated yet and this is where the error of improperly installing it happens.
- Go along gently pushing on the torque converter while slowly rotating it until you hear a tertiary and terminal "clunk." It is now properly seated. If yous continue to push and rotate, yous will hear a scraping noise coming from behind the torque converter. This is normal and one way to tell it is installed properly.
7

Cheque the seating position. Measuring from the face of the commodities holes to the edge of the outer edge of the bellhousing, the torque converter should sit down back 1 ¼ inches or about 3cm inside the bellhousing.
8

Finish up. With the torque converter now properly installed, you may now reinstall the transmission in the vehicle, permitted it is set up for use, or shop the transmission for later use.^[4]

There is an o-ring seal affair only past the spline where torque converter goes. I demand one and don't know what it is called. It's skinnier than whatever o-ring I can notice. What do you lot call information technology?

It's just a torque converter seal. Yous tin can actually pull it off and become to tractor supply and lucifer information technology upwards. It's non any kind of special o-band.

If the torque converter is as well slippery to grasp, clean it of with a rag coated in degreaser or brake cleaner. Another selection is to wear mechanic's gloves.
When the torque converter is removed, it is recommended that the front pump seal is replaced while it is hands accessible.
After the transmission is installed and filled to the proper level with the appropriate fluid, permit the vehicle to idle for a few minutes before moving under information technology's own ability. This is so the fluid can fill the torque converter so that the internals can avert wear from lack of lubrication.

Properly dispose of one-time fluid at a facility that participates in oil recycling and disposal. Improper disposal (such as in a trashcan or pouring onto the ground) is unsafe for the environment and could pose legal penalties.
When the transmission and engine are bolted together, the engine should exist able to turn over by mitt. If at that place is whatever binding or the engine will non rotate, there is something causing resistance. One thought is to check that the torque converter did not move out of place. Do not start the engine until the resistance is solved. Starting may crusade harm to the engine, transmission or both.
If lifting the transmission is required, elevator information technology with another person. Lifting solitary could cause strain and injury.
Clean up whatever transmission fluid spills to avert slipping.
