I like the looks of them, but I am worried about debris hitting a cast pan and it cracking open instead of denting like a steel pan would. Am I worried about nothing, or is this a valid concern?

What I like about the aluminum ones are some have cooling vents and drain plugs :cheers:

I had one on my 700R4 with an extra 1 quart capacity. It also had the cooling fins, drain plug and I drilled and tapped it for a temperature sensor.
I liked the looks, the added cooling capacity and never had a problem with it. If it hits something my oil pan would have been history long before the tranny pan.

Norval,I forgot about that, the oil pan is lower!

You gotta have a drain plug. :yesnod:

The cast alum ones that about 3/8" to 1/2" thick are ok. The stamped alum ones are fragil and most trans shops won't use them as there is a different cofficient or expansion between the pan and the trans and they end up leaking more that a steel pan.

I installed the Deralde pan that holds an extra quart and has the cooling tubes but I did install a drain plug in the rear of the pan. Measuring the pan temp with the cooling tubes and extra fluid it dropped the temp around 15-21 degrees....... :thumbs:

I recently bought one for my old TH400 (B&M cast aluminum with fins and drain plug) - have not installed it as I would have had to alter the bracket for the shifter cable which is bolted to two of the pans bolts.

Just needs a little cutting and welding as it sits half inch lower on the aluminum pan and the recesses around the bolts will not fit the bracket.

Have a look at it in a shop and you will know what I mean (kinda hart to explain).

Meanwhile I have converted to manual... which is far better anyway :cool:

I'm concidering an aluminum pan for my 700r4 also,and found one that measures 4" deep,the stock pan measures 2 1/2". I haven't eyed things up yet,but I'm thinking it's going to be too low.Any thaughts?
