GM Transmissions (A5S360R/390R)
Transmission oil pan will be labeled with either Texaco ETL-7045 or Dexron-III. Fill or top off with proper fluid only. DO NOT mix Texaco ETL-7045 and Dexron-III fluids.
ZF 3HP22, 4HP22 & 4HP24
Transmission identification plate can be utilized to determine proper transmission fitted in vehicle. Transmission utilizes Castrol TQ or Texaco Havoline automatic transmission fluids of the Dexron-III formulation. DO NOT mix any other oil with this transmission fluid when doing repairs or topping off.
A5S325Z (5HP19) & A5S440Z (5HP24)
Transmission identification plate can be utilized to determine proper transmission fitted in vehicle. No subsequent transmission fluid changes are necessary. DO NOT mix any other oil with this transmission fluid when doing repairs or topping off. Use ESSO LT 71141 (BMW Part No. 83229407807).
GA6HP26Z
Transmission identification plate can be utilized to determine proper transmission fitted in vehicle. Transmission fluid has a condition based service interval of approximately 100,000 miles. DO NOT mix any other oil with this transmission fluid when doing repairs or topping off. Use Shell M-1375.4 (BMW Part No. 83220142516).
Transmission Without Dipstick
To top off transmission after a repair, put selector lever to setting "P". Vehicle must be horizontal and secured to prevent it from rolling away. Unfasten filler screw. Top off automatic transmission using filler neck attached to filler aperture until oil emerges at filler/overflow bore. (Scheme 6) Start engine. Top off automatic transmission again until oil emerges at filler/overflow bore. Screw in filler plug. (Scheme 7) Operate brake and, with engine at idle speed, shift transmission through all gears several times. Connect BMW Diagnosis and Information System (DIS) and/or BMW MoDiC to vehicle and perform oil level check in accordance with manufacturer's instructions. Replace sealing ring. Tighten drain plug to 11 ft. lbs. (16 N.m).
