• Q: How to Replace the Automatic Transmission Filter and Fluid on 2001 GMC Safari?

  A: The replacement process of automatic transmission fluid and filter begins with vehicle support and a drain pan installed under the transmission Oil Pan. If your transmission has a Drain Plug then remove it but sometimes you will need to unscrew all bolts which allows placing the range cable bracket out of the way to lower the pan without detaching the cable. Oily pan bolts need to be taken from the front and sides while loosening the rear bolts about 4 turns before using a rubber mallet to gently tap the pan to drain oil. Drain the steps and then eliminate the remaining pan bolts before removing the Oil Pan and its gasket. Twist the filter firmly before pulling it out and proceed to remove the stuck filter seal with pliers if needed. Throw away the seal before examining fluid color and checking the filter against clutch material particles as well as bronze slivers and steel debris. Solvent should be used to clean transmission case and Oil Pan gasket surfaces before removing all remaining gasket material. To install the new filter seal apply automatic transmission fluid onto it before placing it inside the transmission case while tapping it with an appropriate socket. Begin by setting the new filter then install the Oil Pan and new gasket on it. Reinstall the range selector cable bracket followed by tightening its bolts to 25 nm (18 ft. Lbs.) while you should install the Oil Pan bolts with alternating and even torques of 11 nm (97 inch lbs.). You should apply gm p/n 12346004 sealant to the Oil Pan Drain Plug threads if present then bolt it down with 18 nm torque (13 ft. Lbs. Force). Continue with the fluid introduction at the proper dexron(R) iii transmission fluid level while evaluating both cold fluid position for starting and searching for potential Oil Pan gasket leakage.
