transmission pans are designed for and around the space available on a stock
vehicle. Because our transmission pans are larger and shaped differently than
stock, if you have
added any aftermarket parts located near the transmission such as exhaust
components, you must check to be sure that contact between your new transmission
pan and other parts of your vehicle will not occur.

- Position a large oil drain pan
underneath your old transmission pan.
- Prepare for large amounts of red
fluid to drain from around the perimeter of the pan.
- Loosen all perimeter mounting
bolts. Remove all but 2 bolts located on one side of the pan.
- Carefully insert a putty knife or
gasket scraper between the stock pan and the transmission (be careful not to
gouge the gasket surface of the transmission) on the side opposite the 2
remaining bolts to break the seal. Pry the pan slightly away from the
transmission to allow the oil to drain.
- Once the oil has drained, remove
the remaining bolts and remove the pan.
- Remove all old gasket material
and oil from the machined gasket surface of the transmission. Be careful not
to damage the machined surface. This surface must be clean and dry for the
new gasket to seal properly.
- Remove the old transmission
filter and replace it with a new one.
- Place a new transmission pan
gasket on the PATC transmission pan.
- Compare the threaded part of your
original bolts to the new fasteners provided with your PATC transmission
pan. The thread diameter and threads per inch should be the same.
- Carefully place your new
transmission pan with gasket up against the transmission and install the
perimeter bolts. Snug all bolts up against the transmission pan flange.
- Tighten bolts in a criss cross
pattern, a little at a time. Torque bolts to 15 ft-lbs.
- Torque drain plug to 25 ft-lbs.
- Fill the transmission with new
oil. Refer to your vehicle service or owners manual for the proper type of
oil and filling procedure.
- Your new PATC transmission pan
will hold 2-4 quarts more oil than your stock pan (the exception is our low
profile pans which are stock capacity).
- Once the proper oil level has
been achieved, drive your vehicle for 20 minutes or more to allow the oil to
get hot and check the oil level again. Add oil as needed to get the level to
full on the dipstick.
