DESCRIPTION


Since June 1, 1989, the diameter of the torque converter pilot boss on the captioned model has been increased from 20 mm to 21 mm.

In accord with this modification, the configuration and inner diameter of the drive plate adapter have been changed so the pilot boss can be fitted to the engine.

When installing a transmission that has a modified torque converter on a vehicle produced before the modification, please be sure to replace the drive plate adapter with a modified one. However, if you are installing a transmission with the old torque converter on a vehicle produced after this modification, be sure to use an old drive plate adapter also.
