How Do I Change the Transaxle Fluid on a 1997 Buick Park Avenue?
- 1). Raise the front of the car off the ground with a jack and support it with jack stands. Position an oil drain pan under the transmission oil pan and remove the mounting bolts around the front and sides of the transmission pan with a socket and ratchet.
- 2). Loosen the remaining bolts to allow the pan to drop on one end. Allow the old transmission fluid to drain from the pan, then remove the bolts and drop the pan down from the transmission.
- 3). Clean the old gasket material from the pan and transmission with a gasket scraper and wipe out the pan with a clean rag to remove any metal shavings or other debris that may be in the pan.
- 4). Install a new gasket on the oil pan and raise it up to the transmission. Install the four bolts at the corners, tighten them evenly with a socket and ratchet until the pan is snug. Install the remaining bolts and tighten them with a socket and ratchet.
- 5). Torque the bolts to 10 foot-pounds with a torque wrench, then position the jack under the car. Raise the car off the jack stands, remove them, and lower the car to the ground.
- 6). Place a funnel in the transmission dipstick tube in the engine compartment and fill the transmission with GM-approved transmission fluid. (Dextron/Mecron 3 or better is recommended for this car.)
- 7). Start the car and let it run until the car is at normal operating temperature. Place the car in neutral with the parking brake on and check the level of the fluid on the dipstick. Continue to add transmission fluid until the dipstick reads full.
