Machining Process:

Goerend pans are machined using three operations performed by in-house Mazak CNC machines. Operation #1 includes drilling bolt holes on the bottom side of the pan. Operation #2 includes machining the surface of the pan to create a leak-proof seal against the pan gasket. Operation #3 includes drilling and tapping the hole for the temp sender and drain plug.

Frequently Asked Questions:

What's the difference between this pan and other aftermarket pans?

We designed our own pan to get several features that we could not find in other aftermarket pans. The interior of our pans have a sloped floor so that all the fluid can drain out. Our drain plug takes a 1" socket; no more stripped Allen heads or threads. The drain plug in our pan is magnetized, and is at the lowest point in the pan in to catch any magnetic debris. Other drain plugs sit above the bottom of the pan and will not catch debris. The exterior of our pan is flat, allowing the transmission to sit on a jack without rocking. The sides of our pan are not ribbed, increasing its strength. Our pans are intentionally designed to be more fragile than the transmission case. Other pans that are excessively beefed up are too strong and tougher to break, which will then result in the breaking of the transmission case instead. It is much easier and cheaper to replace the transmission pan than the transmission case.

Do you have any tips on installing the pan?

Start all of the pan bolts by hand to prevent cross threading. The pan should have play in all four directions with all of the bolts started by hand. Start by tightening four bolts, one on each corner of the pan until snug, and then snug the rest of the bolts. Torque the four corner bolts to spec, followed by the rest of the bolts.The included bolts engage more of the case threads than the stock bolts. Case threads that go all the way through and are exposed on the top side may have dirt packed into the threads. In some cases, this dirt will cause the bolts to feel snug before the pan is tight to the case and a leak at the gasket surface may result. Case threads should be thoroughly cleaned prior to pan installation. A 5/16th diameter x 18 threads/in. tap may be used to clean dirt from the exposed threads, by carefully running the tap through the threads from the bottom up. The tap should start easily and not require much force until the obstructed threads are reached.

How do I troubleshoot alignment issues?

The valve body is not aligned to the transmission case with anything other than the valve body bolts. The valve body should be aligned so that the portion of the rooster comb that sticks up through the case, and has the shift cable lever attached, has 360° of play and is not rubbing the hole in the case. All of our pans are checked for fitment with a valve body as part of the machining process. If you have trouble aligning all of the bolt holes to the case, or the pan seems tight to the valve body, you may need to loosen and adjust the governor solenoid retaining bracket. This area has a very tight clearance to the pan. To adjust, simply loosen both T25 Torx screws and the three 7/16” valve body bolts that go through the governor bracket. Slide the bracket away from the pan edge, and retorque the 7/16” bolts to 100 in-lb. and the T25 screws to 35-40 in-lb.
