Refill transmission fluid on 2002 Buick lesabre custom?

Answer 1

If your 2002 Buick Le Sabre Custom has more than 60,000 miles without a transmission oil change under normal conditions the oil and filter should be replaced. Dusty conditions require more frequent oil and filter changes.

The transmission pan should be removed, oil drained, and the old filter removed. Clean the oil pan, replace the transmission oil filter with a Delco, Fram, or like quality filter; properly replace the oil pan with proper bolting sequence to avoid leak, and refill with the correct transmission oil.
