TITLE TORQUE CONVERTER MOUNTING BOLTS


When reinstalling the transmission assembly after repair or replacement, it is critical that the correct torque converter mounting bolts are used (refer to applicable Parts Micro-Fiche or the attached part number information for application and part numbers).

The use of a longer torque converter set bolt than specified causes a projection on the front cover of the torque convertor. This projection can internally damage the torque converter lock-up clutch disc. Material from the lock-up clutch may contaminate the transmission and valve body requiring additional repairs. The damage that may occur, cannot be seen or detected by the technician.

When the torque convertor is moved in the direction of the flex plate by installing and pulling the temporary bolts, these bolts must be hand tightened.

Note: One of the torque converter mounting bolts is a different color than the other five, this one must be installed first and hand tightened only. This is necessary to center the flex plate onto the torque converter.

When installing the other five mounting bolts:

^ hand tighten the bolts first.
^ progressively torque all six bolts in a three step process and in a cross pattern (see illustration below) to factory specification.

Refer to applicable repair manual for torque values.
