What is the recommended transmission fluid for the b7xa-transmission in a 1996-1998 Acura TL?
The b7xa-transmission requires Honda/Acura Genuine ATF-Z1 or an equivalent automatic transmission fluid meeting Honda/Acura specifications. The fluid capacity is approximately 7.4 quarts (7.0 liters) when drained and refilled, and up to 9.5 quarts (9.0 liters) during a full flush.
Q2 What is the torque specification for the b7xa-transmission drain plug?
What is the torque specification for the b7xa-transmission drain plug?
The drain plug for the b7xa-transmission should be torqued to 36 lb-ft (49 N·m). Ensure the transmission pan is clean and the sealing washer is replaced to prevent leaks.
Q3 How often should the b7xa-transmission fluid be replaced in a 1996-1998 Acura TL?
How often should the b7xa-transmission fluid be replaced in a 1996-1998 Acura TL?
Acura recommends replacing the transmission fluid every 30,000 to 60,000 miles, depending on driving conditions. Severe driving conditions, such as frequent towing or stop-and-go traffic, may require more frequent service.
Q4 What are the symptoms of a failing b7xa-transmission?
What are the symptoms of a failing b7xa-transmission?
Common symptoms include delayed engagement, slipping gears, harsh shifting, unusual noises (e.g., whining or grinding), and transmission fluid leaks. If any of these symptoms occur, immediate inspection by a qualified technician is recommended.
Q5 Can the b7xa-transmission be rebuilt, or does it require a full replacement?
Can the b7xa-transmission be rebuilt, or does it require a full replacement?
