  Q: How to Replace the Automatic Transmission Filter and Fluid on Buick Rainier?

  A: Beginning an automatic transmission fluid and filter replacement requires first that technicians raise and support the vehicle. Access will become possible after removing the Catalytic Converter. A drain pan should be installed under the transmission oil pan and you should remove the Drain Plug when fitted. Detach the range selector cable bracket bolts only if needed for clearance before lowering the pan while maintaining the cable connection. Start by removing bolts from the front and sides of the oil pan and turn the bolts at the back approximately 4 turns. You can drain transmission fluid from the oil pan by lightly tapping it with a rubber mallet before removing all remaining bolts and the oil pan along with its gasket. Grab the filter with care before twisting until it slips out and extract the filter seal by using pliers to unlock it when needed. You should examine the fluid color and check for clutch material along with bronze slivers or steel particles in the filter before discarding the seal. The transmission case along with Oil Pan Gasket surfaces require solvent cleaning before air drying until no residue from the old gasket remains visible. Spread automatic transmission fluid onto the new filter seal before placing it into the transmission case by using a suitable socket for installation. After installing the new filter, install the oil pan with its new gasket while tightening bolt specifications of 11 n.m (97 lb in) after alternately adjusting the torque. Replace the range selector cable bracket and firmly tighten its bolts to 25 n.m (18 lb ft). Use gm p/n 12346004 sealant to treat the oil pan Drain Plug threads before tightening it to 18 n.m (13 lb ft). Place the new Catalytic Converter then lower the vehicle down before filling the transmission with dexron(R) iii transmission fluid while checking only the initial cold fluid level. Conclude the inspection by checking the Oil Pan Gasket to detect leaks.
