Here's the procedure for replacing your transmission. However, I recommend you purchase a single-vehicle subscription to a data service such as AllData or Mitchell-1. These will provide you with illustrations as well as helpful hints and tips.

4T60-E TRANSAXLE REMOVAL AND INSTALLATION

INSTALL OR CONNECT

* To complete installation, observe the following assembly tips and reverse the removal procedures.

ASSEMBLY TIPS

* Use care when installing right side drive axle into the transaxle case. The splined shaft can easily damage the seal.

IMPORTANT

* Before installing right side drive axle, be sure to install tool J 37292-B axle seal protector.
* Line up the flywheel to torque converter marks made at disassembly.
* Torque converter to flywheel bolts should always be tightened twice. The final torque should be 62 N.M (46 lb. Ft.).
* Check adjustment of the shift cables. Readjust as needed.
* After installing front wheel and tire assemblies, torque wheel nuts to specifications.
* When installing cross brace to struts: 1. Place assembly on inboard strut studs.
2. Install strut stud nuts and torque to 24 N.M (18 lb. Ft.).
3. Torque bar assembly through-bolts to 28 N.M (21 lb. Ft.).

O Check and adjust the fluid level as needed.
O Road test and check for leaks.
O When installing transaxle to engine block brace, tighten brace to engine bolts first and brace to transaxle case last to avoid pulling transaxle case out of line.
