Nissan Tech Tip: Worn A/T Differential Pinion Shaft

Nissan Tech Tip: Worn A/T Differential Pinion Shaft

Debris from a worn differential pinion mate shaft can cause the following: slipping on acceleration; hesitation and/or stalling when cold; and abnormal noise coming from the transmission while driving. A countermeasure transmission differential case, with improved lubrication to the differential pinion mate shaft, has been developed to resolve these types of transmission incidents.

Debris from a worn differential pinion mate shaft can cause the following:
• Slipping on acceleration;
• Hesitation and/or stalling when cold; and
• Abnormal noise coming from the transmission while driving.

A countermeasure transmission differential case, with improved lubrication to the differential pinion mate shaft, has been developed to resolve these types of transmission incidents.

Applied Vehicles:
• 1992-’94 Maxima (J30 – VE30DE engine);
• 1995-’96 Maxima (A32);
• 1993-’96 Altima (U13); and
• 1994-’96 Quest (V40).

Applied Transmission:
Transmissions built prior to #4Y22962 or #8Z53044 (depends on production line).

SERVICE PROCEDURE:
1. Verify the customer’s complaint. If the transmission exhibits slipping on acceleration, hesitation and/or stalling when cold, or any abnormal noises coming from the transmission while driving, and no trouble codes are found in self-diagnosis, remove the transmission oil pan and inspect for metal debris.

2. If excessive metal debris is found, disassemble the transmission and inspect for burnt or worn components. If wear marks are found on the differential pinion mate shaft (refer to Fig. 1), replace the shaft and install a countermeasure differential case (P/N 38411-81X01). Replace all other burnt or worn components as necessary.
