How do you replace the transmission filter on 1994 gmc sierra?

To replace the transmission filter on a 1994 GMC Sierra, begin by raising the vehicle and securing it on jack stands. Drain the Transmission Fluid by removing the transmission pan bolts and carefully lowering the pan to avoid spills. Once the pan is off, remove the old filter, install the new filter in the same position, and clean the pan’s gasket surface. Finally, reattach the pan with a new gasket, refill the transmission with fluid, and check for leaks.
