904 Transmission pan

One thing the aluminum pan will do is dissipate heat.
I have the Summit Pan and a B&M pans.
The B&M was beefier but was not needed.
The aluminum pans are said to add to making the case more rigid.
The Summit was easier for me to do my sillyness with.
The B&M was almost free to me as was a raffle item.
I have pictures of them B&M while making it look good.
Remember you need longer bolts with the cast pans.
So get some if you go that route
