Bottoming out tranny oil pan.....Solutions?
I'm tired of my stock pan hitting speed bumps, etc. And yes, I do come to a full stop at them & creep over them.
Which would be stronger?
Jegs cast aluminum oil pan?

or.......
Trans-Dapt Steel skidplated pan?

im going with the skid plated pan only because if you bottom out the aluminum pan there is a good chance you will crack it and therefore it will leak wheras the steel pan can take more abuse and bend easily than the cast aluminum

I agree steel will be more forgiving, aluminum will break easy. Take transmission bolt corners for example 5lbs over torqe and it snaps off.

You could always make a custom skid plate to go underneath the trans pan. I have one on my engine oil pan and my trans pan just a thin piece of steel that sits 1/8 inch away from pans and attached to frame...easy to make and install.....but I usually scrape exhaust before anything...

Aluminum rims seem to bend much easier on potholes than the old steel ones did, so I'd think the steel one would be better. ( I know - weird analogy, but it works in my head)

Re: Bottoming out tranny oil pan.....Solutions?
See......I agree with everyone on the steel plate vs the cast aluminum pan. But this is what prompted me to post & ask. others opinions.
A Jegs Sales Rep. is basically advising me to go with the $50 pan they sell, not the $150 pan they sell. Wouldn't a Sales Rep/ always suggest the more expensive product, unless they firmly believed that the cheaper cost one was BETTER?
"All of the steel plates in the entire line are welded into place on the pan. We have sold a number of pans in this line over the years and have seen very little problems with leaks, etc. If you are still concerned, may I suggest a cast aluminum pan for your 700R4. This will be stronger than any stamped steel pan available and also offer more support to the structural integrity of the transmission case."
I can weld, so I'd make my own that way first & it would be cheaper than the $50 aluminum one. But if the aluminum one IS stronger, I'd rather spend the $50.
