a billet one was done by that Hungarian man who rebuilt his entire car a while back. he did a yellow billet aluminum tranny pan with cooling fins in a day with his C&C machine. its not only looks bad ass and 10x beefier but also looks to have more depth so probably added capacity and cooling all in itself.

Yeah that was @CSL335I

And to be clear, i'm not saying I have all the answers. Hardly.

We will have to research a good way to log temperatures. I keep kicking myself for not posting my transmission cooler and oil cooler setup. Despite not having the numbers to back up my cooler, I have a lot of real world testing to add. I have done track days at brutal tracks like Road America. I tow 2000 pound trailers in 90 degree traffic and at highway speed. I like to nail the throttle constantly. Oh I love burnouts . I feel like If my cooler was setup the wrong way, the tranny would have been gone by now.

TheeGovernor - feed me your ideals... i want one to. and i have the parts to do it

That is a diff cover. I think I remember a DCT tranny cover but that is not it.

EDIT: scratch that didn't scroll down enough. Here is the direct post link.

Yeaaa that's what we need. A billet pan would be outstanding.

@TheeGovernor the real world results are what matter. Everything i've discussed is based on paper and short-term testing. So if your car is running great I can't sit here and say "no way". How much WTQ do you estimate you are putting down?

And yea recording trans temp isn't as easy as it seems either. There's a surprising lack of information RE: HP21 operating temperature range. I'm lazy and haven't read the full ZF booklet for it so maybe it's in there.

When I am at sea level I was running map1/5 with e85. At altitude I run map 1 with e85. No downpipes and need to get a fmic.

At elevation you probably aren't making the torque and heat that is going to smoke the clutches or make things generally unhappy. Once you mess around with more E85 and can push more aggressively, of course that'll change.

My car stays happy until something around 450WTQ. Get much north of that (granted that's starting to near the limits of stock wheels) and the 3-4 shift is not pleased.

I emailed my cutsom fabrication company the specs on the billet aluminum tranny pan just to see if its financially viable for me. If i can coerce them into making a few of them to cut costs would anyone be down for it.. im just thinking out loud i asked if they even could do something like that. Making custom 104mm turbos on supras and roll cages is different fabrication than tranny pans cut by a C&C machine.

Cost? I'm in if it's under/at/around $1K. No idea how viable that is from a cost standpoint, billet C&C work is not cheap.

[jyeah]

I'm very interested if someone can fabricate a billet transmission pan and also a billet differential cover for the AT. Those the last two pieces of modifications that I might ever do for this car.

I did look into adding an oil cooler setup for my transmission, but decided against it.

Same here, I am in too if it is under $1k.

Just one thing though, stock plastic pan has the suction filter built into it, while the DCT has the filter separate from the pan.

MY thoughts gents, and the ideals i sent to the company are to go with a Billet pan similar to the one CSL built, i wanted it to dip down a little more to incease fluid capacity as well as have the channeled oil cooling fins, also wanted two pre drilled AN tapped fitting for follow on oil cooler/oil pumps. Any input greatly accepted. I have NO clue what custom billet work costs. I have a friend in fabrication and that might be the way to go, then they would come from his shop in NM. Anyhow input accepted. would we have clearance issues from exhaust or something if i dipped it down about an inch or 2??? my car is back home i am deployed so work with me.

I'd need to get the car back on the lift but when I do, I can take pictures to get a better sense of clearances etc.

Off the top of my head, 2" would start to worry me a bit from a ground clearance standpoint. On a lowered car that's starting to skirt things tight.

Think you are headed down the right path though man! Let me know how I can help.

[4doorbmwpower]

my lowest point on my car right now is my massive HPF gen 2 exhaust. im going to get a section re bent to conform to my car a little more its realllllly low! Ill let you all know and keep you updated. I have my buddy who machines working with me also, If i can do this for a decent price ill order enough aluminum for 5 and ill sell them on the forum. If they all sell decently fast ill buy 10 more blocks of aluminum and go from there, i see a demand but hopefully it isnt uber expensive.

are we all in agreeance that increasing oil capacity is beneficial?

[Cloud9blue]

What do you plan on doing with the filter funnel that is built-in with our pan.

+1 to that question


And there is absolutely no question that adding fluid capacity in a billet pan with serious thermal rejection (fins) will help with longevity and cooling. The OE pan makes no serious attempt to actively shed heat in comparison. Look at the Gintani pans they're beautiful

[4doorbmwpower]

built in funnel? are you talking about the spire? the little part that builds upwards? or the concave nature of the pan? because that is simple enough to replicate out of billet aluminum. .. enlighten me

[4doorbmwpower]

talking to some people about that, i am brainstorming, open for ideas. maybe a replacable filter section.?

[ajsalida]

Great discussion here.

Maybe if cost was too much of an issue with a full billet pan, something like a spacer (with or without fins, not nec. billet either) could be made between tranny housing and stock pan, say 2" thick with proper extensions and fittings for filter. Same gasket footprint top and bottom.

IOW spacer just drops the existing pan down couple of inches, make sure everything matches up inside, add a whole bunch more fluid capacity.

[4doorbmwpower]

good idea there ajsalida, that may also make a problem with the stock filter however? anyone think that would make a problem? if not thats a viable option i would look into machining if this ends up not being cost effective. Right now im having the engineers look at adding volume cooling fins and two pre tapped AN fittings to add a tranny cooler and recirculation pump to our tranny.
