Photo 4/11 | strong And Cool Aluminum Covers draining The Transmission | The stock stamped-steel transmission pan doesn’t have cooling fins that provide much surface area, or big ribs that provide strength. It also has 4 quarts less fluid capacity than PPE’s pan. We had Auto Body & More in Santa Rosa, California, do our dirty work so we could snap photos of the PPE upgrades.

The stock transmission gasket can also be used with this pan. The 1/4-inch and 1⁄8-inch NPT ports allow for temperature fluid sensors. The 5⁄8-inch internal baffles absorb heat from the fluid and direct it toward the filter pickup. The retail price for the pan is $329.99.

Then the gasket and pan were installed with the included Allen bolts tightened to 10 to 12 ft-lb in a crisscross pattern to avoid distortion. Auto Body & More then filled the transmission with about 9 quarts of transmission fluid. Then it brought the truck up to operating temperature, parked on a flat surface, and put the transmission in neutral while the engine was running to check the fluid level. It’s always important to be sure to not over or under fill an automatic transmission. You can also measure the amount of fluid you drained from the transmission and then add that much back in— assuming the level was correct to begin with. Also, make sure to add an extra 4 quarts to meet the new pan’s capacity.
Photo 8/11 | strong And Cool Aluminum Covers draining The Differential | The stock stamped-steel differential cover doesn’t provide as much cooling or fluid capacity as PPE’s cover. The original one has no drain plug, either. So just like with the stock transmission pan, a messy and time-consuming removal will occur every time the fluid is changed.

Photo 10/11 | strong And Cool Aluminum Covers ppe Diff Cover | The PPE differential cover is cast from A356-T6 aluminum and comes with 1⁄8-inch and 1/4-inch stainless steel temperature-probe access plugs. These access points could also be used for running wires or lines for locking differential devices. There is a 3⁄8-inch NPT stainless steel drain plug and 1-inch magnetized fill plug. The cover comes with a CMP-4000 high-compressed gasket featuring a synthetic-fiber matrix and fully cured nitrile butadiene rubber binder. It can take short-duration maximum temperatures up to 650 degrees. We decided to use the original reusable gasket shown here.

The PPE heavy-duty differential cover retails for $329.99. The original rear differential fluid capacity is about 4 quarts. The PPE cover adds another 4 quarts to the differential. Gear lube was pumped into the fill hole until it started to run out, signaling it was full.
