Don't you think the engineers of those transmissions, have kept such an extreme usage in mind, when designing the transmission including its cooling? Especially when its an AMG performance car?


If the cars where optimum then Brabus, Carlsson and so on wouldn't exist. There are many things that(AMG) and (Mercedes) do that are not optimum. For example your E55 has the same radiator/trans cooler as a e280cdi or e320 cdi. The way we look at it, these cars are not stock, making more power equaling more heat and stress on engine/trans components.

Not even the other well known larger German tuners developed something like that AFAIK, look at Brabus, Carlsson, Lorinser, MKB, Väth, Hagmann, and so forth - as i believe they think its not neccessary.


Different companies have different priorities in what parts they make. For example we are still the only company that makes intercoolers for the v12tt motors, which are proven to give great horsepower and cooling.

Not to bash the vendor here, but i believe this item is unnecessary/i would like to hear your opinion on that item and correct me if i'm wrong with my assumptions.
Also i don't think adding more ATF volume is very good for various reasons - it takes longer to warm up, noone knows the perfect level now anymore, as the universal dipstick thats available will reach till the very bottom of this new pan, etc.



The pan is designed so that there is shelf replicating stock height from the oem pan. The is measured perfectly like original. It doesn't take much longer to heat up to operating temps.

EDIT: It might be totally different for continuous track races though, so please correct me if im wrong.

Answered above

This mod is common place in domestic th350 th400 and c4 trans where heat is a killer when running high stall converter with no lockup.


Also answered above

The question is will the extra heat dissipation of the extra sfc area of this lower slung pan matter vs the existing trans cooler.


Of course it matters, the entire valve body sits there and it is where the fluid is taken from.

Now bling factor is off the charts for sure and I don't see a downside to a little more volume and hear removal. All my humble opinion.

Larger radiator from 3 to 4 core does not lower temps but gives added heat dissipation/volume. AMG uses a 9.5 liter engine oil capacity, why? because they must have seen issues with running a 5 0r 6 liter capacity,` More` usually means it has some benefit. Now for those cars that are lowered, there may be an issue with clearance to speed bumps and pot holes, just saying. The aluminum finned design should offer increased heat transfer over the steel component as well as the additional capacity which can absorb and transfer this heat efficiently. IMO
Would like to see one installed to observe the actual drop this pan will have below the other components, like the exhaust pipes which could serve as a heater to the sides of the deepened pan.

@Speedriven1, any idea when you are coming out with a billet pan for the 63's 7 speed trans. Impressed on the install pictures, could see putting a small scoop in the plastic cover to direct air around the pan. Looks nice and of course functional.

I see the "Don't you think the Engineers considered this when making a car that can stay WOT for minutes on end at max speed" argument all the time, be it for AMG's or any other high-end performance car. Here's my take:

Do you need this pan on a stock car? Nope. The transmission cooling system is more than adequate.

Are any of these cars stock anymore? Nope. We mod the **** out of these things and push WAY more horsepower (and heat) than AMG considered.

We have PLENTY of guys running higher stalls in their 55's. Just that mod will throw the tranny up 40-70° in my experience. HEAT IS WHAT KILLS TRANSMISSIONS, so anything you can do to mitigate that heat is a step in the right direction towards longevity and reliability.


Long story short is that I think this could be a great mod for the guys with converters and big pulleys. It's also a beautiful piece.

Also, claims of lower temps both idling and running, do you have some actual empirical values to share? (For example, you see a 10% drop or 15 deg C drop? etc) I'm just trying to get some sense of observed temp improvements but realize this would be a general claim and could vary based on ambient and other factors.

Kinda overkill though cutting out of a billet. You should get a mold made from this and start casting them to bring the price down
