# Service Information on Automatic and Manual Transaxle Design Changes to the Differential Assembly Pinion Gear Shift

Subject: | Service Information on Automatic and Manual Transaxle Design Changes to the Differential Assembly Pinion Gear Shift

Models: | 1996 Saturns built after and including VIN TZ377906 and 1997 Saturns

### Purpose

On vehicles built after and including VIN TZ377906, a design change was made to the automatic and manual transaxle differentials that loosens the fit of the differential pinion gear shaft lock pin to the front differential pinion gear shaft.

This change involves increasing the diameter of the hole in the front differential pinion gear shaft which the differential pinion gear shaft lock pin slides through. As a result of this change, there may be a loose fit condition that exists between the differential pinion gear shaft lock pin and the front differential pinion gear shaft. This condition is normal and does not affect the performance or reliability of the transaxle.

B Second Design

1. Differential Pinion Gear Shaft Lock Pin
2. Front Differential Pinion Gear Shaft
3. Larger Diameter Hole in Front Differential Pinion Gear Shaft
