Mag-Hytec

[GOakes]

I've looked at the new extra deep Mag-Hytec transmission pan and the concept is compelling. The additional fluid capacity looks be a plus and the ribbed aluminum would (seem to me) aid in cooling , but strangely I haven’t found any claim (by the manufacturer) to that effect. The other side of the coin is that I’m concerned about the ductility of on the metal. That bugger hangs down in “harm’s way”. Yeah, I realize the transmission support member is even lower, but it can take a whale of a lick and leave the truck operational. The OEM pan is steel and while it can be punctured or ripped there is little likelihood it would shatter on impact.

Having said all that the question is --- If the Mag-Hytec pan were hit with a blow that would seriously dent the OEM steel pan would the Mag-Hytec pan yield (by denting) or would it shatter?

What’s your experience with Mag-Hytec pans or covers? How tough (or fragile) are they?

I put one on my truck. It is a pretty tough piece. It is aluminum and could break I guess.

I dont think the gear case temp will drop much, if any. It just may take longer to get there.



My experience: Bozo at National Tire and Battery jacked the rear of my truck up by the thing. There is a drain hole in the bottom of the cover... this is were he lifted the truck from.

It held but I was worried about it and asked him to try again.

The pans and the rear covers are tough. I have both. I think a rock might break it but that same rock would probably cream the stock pan too. I don't think you get any extra cooling with the double deep, you just get more fluid capacity. Fins are the same as on the regular Mag-Hytec transmission pan so the cooling effect should be the same. I've never had a transmission temp problem and with my 4x4 I don't want anything that hangs down too far. I guess it boils down to personal choice. More fluid or more clearance...

I gotta read these post more carefully... I thought you said rear end cover.



Ooopps!

As a dealer and installer and one who puts them through their trials, I can say that the added fluid capacity is a plus. The aluminum construction with the fins are an excellent conductor of heat to keep the fluid cooler. The DD pan doesn't hang down too obtrusively low. Even on a transmission with an "extra tight" convertor, I have noticed only 190 degrees transmission temp when beating the living sh** out of it. BUT I have nothing to compare that to as the truck already had the pan before the install of the TC. Either way, the product is built way tough and pretty darn heavy for aluminum.

I plan on putting on the DD Mag-Hytec. Bill K. of DTT thinks there is extra benefit (cooling) from the deeper pan. Additionally, both Mag-Hytec pans make draining your fluid much easier and a lot neater.

Mag Hytec pan?

One obvious advantage to either the deep or extra deep pan that all have failed to mention is RIGIDITY. The 727 trannys and their clones are all using a huge opening in the bottom of the case casting to accomidate the single valve body design. This desigm makes sevice easier but creates inherent weakness in the case. This allows trannys ,especially the high horsepower diesels, to twist the case of the trannies. Remember that the roots of this transmission are in the high horspower hemi days but horse power at 6000 RPM is vastly different from horspower at 1600 RPM so common on the diesel. The Mag Hytec pans help prevent twisting and should help protect the pump and other internals from deformation scuffing and stress fractures.

After installing my Dana 80 cover, I will say that if the DD trans pan is built to the same thickness (and I assume it would be) an impact severe enough to break through the pan would cause significant enough damage that it (the trans) would probably be the least of your worries.



My floor jack catches my diff cover all the time, no problem!
