How to change the transmission gasket on a 1988 chevy Silverado
Changing the transmission gasket on any car..
You need to drain the transmission fluid - if you get under the car you will see the transmission pan drain plug.
Drain the transmission fluid and then remove the small bolts that hold the fluid pan to the transmission body. You may need a blunt screw driver to break the seal/lever the pan off. Be careful when levering as you don't want to damage the mating surface of the fluid pan.
With the fluid pan removed use a blunt screwdriver to scrape off the old gasket from the pan and the transmission body. Apply a thin smear of sealant to the pan and place the new gasket onto it - line up the holes in the gasket with the bolt holes in the pan.
Lift the pan up against the transmission body and put the bolts in finger tight to hold it into place, then tighten with a socket to pull the pan tight against the transmission body.
To refill the transmission with fresh fluid (don't use the old fluid) have a look on the side of the transmission itself. There will be a filler plug that needs to be unscrewed. Alternatively, you can rig up a funnel/tube and fill the transmission via the transmission dipstick tube. This method takes longer but it tends not to be as messy as filling the transmission via the filler plug.
However, before you start any work on the transmission gasket check that it is actually that gasket at fault. Fluid above/in front the transmission pan can point towards a leaking torque converter.
