Repeating "Heat is the number one killer of all drivetrain parts," never seems to get old. Perhaps it's because it's one of those things that, no matter how well you know it, you'll ignore someday and it'll bite you in the ass. We've fried multiple transmissions, axles, transfer cases, engines ... you name it, we've fried it. That's why adding coolers and extra-capacity pans to engines, transmissions and axles is never a bad idea.
Mag-Hytec is known for having some of the highest quality items available for transmissions and axles of all kinds. The aluminum pans not only house more fluid than a factory pan, they are also stronger, and have magnetic drain pans, dipsticks, and threaded holes for temperature senders.
Since Jeeps R Us in Laguna Beach, California, services more than just Jeeps, we went down to have them pop on a Mag-Hytec transmission pan and differential cover and fill them back up with some delicious Royal Purple fluids (do not drink).
We used an infrared heat gun to check temperatures, and found an almost 30-degree difference between the stock transmission pan and the Mag-Hytec pan after only driving home from work. The differential showed a 25-degree difference. We can only imagine how much the new tranny pan and differential cover will help when we put a real strain on the vehicle, towing or off-roading.
 All Mag-Hytec pans and covers...  All Mag-Hytec pans and covers are cast A356-T6 aluminum and have O-rings that seal the pan/cover to the housing instead of using a gasket. The differential covers feature a dipstick that does not get in the way of any differentials or gear ratios we've ever tried. The dipstick hole also makes filling the axle with gear oil very easy. The pans/covers also feature a magnetic drain plug that grabs metallic particles in the fluid, and a threaded hole (with an included plug) in case you want to run a temperature sender. |  We did not run a sensor on...  We did not run a sensor on our rear axle, but we did install a sender on our transmission pan. |  The new Mag-Hytec tranny pan...  The new Mag-Hytec tranny pan is definitely deeper than the factory pans (which was a concern, of course, since we're off-roaders), but the Mag-Hytec pan was still higher up than our crossmember or torsion bars, so we felt safe with it. The pan is also much stronger than the factory pans; even if we did hit it, there's a good chance it wouldn't make a difference. |
 The transmission pan gasket...  The transmission pan gasket almost fell off it was so easy, but Richie Estrada had to scrape the rear axle cover's gasket off. Once you get the surface good and clean, the new mag-Hytec cover should seal to the axlehousing and never leak. |  With the cover secured in...  With the cover secured in place (with the included stainless allen bolts), Estrada poured some Royal Purple SAE 75W-90 gear oil into the axle. We ended up pouring about two more quarts into the axle than it normally takes. |  The dipstick in the Mag-Hytec...  The dipstick in the Mag-Hytec diff is a nice feature when filling your axle, but you might think you'll never use it again after that. If that's the case, then you've obviously never had bad axle seals and run your differential dry. |
