Dear fellow people who track their cars, any of you have experience where shifting up from 3 - 4 after a couple of laps would be really slow? At first I thought it was only on my car because of the extra power, but i have a friend who has the same issue completely stock. Apparently it is because of the tranny overheating, can anyone confirm or deny?

On a side note, anyone have the weistec tranny pan? Comments?

Yup. Transmission gets grumpy and slow during long track sessions. The Weistec TCU/VB upgrade helps but sadly they don't offer it anymore. I'll be looking to upgrade my trans cooler over the winter, so stay tuned for details.

I have the Weistec trans pan. I don't think it does much for temps, but I like the extra capacity as insurance.

Doesn't the 44o already come with a bigger trans rad? You planning to upgrade over that? So you think worth getting the pan or save my $$?

BLKROKT

Nope, 44O only has bigger oil coolers.

I think the pan is good insurance with 50% more fluid capacity, and the cost is reasonable enough. It's cheaper than a new trans, and you have to believe that it can only be helping.

I have Weistec Transmission pan on my CLK BS,
It had 1.8L of oil which is approximately 20-25% more than stock
Without Gearbox oil temp on the cluster, impossible to know how it improve cooling.

Cli63

Anyone tried installing a trans temp gauge? Shouldn't be that hard?

Tex5

Gearbox oil temp is available in MB SDS, so perhaps it can be activated on cluster in dev mode, but I do not have the procedure

Larger fluid capacity will only increase time it takes to overheat not solve the heat problem. The weistec pan has -8 fittings for an additional cooler that could be mounted under the trunk with a fan on it. That would likely solve the issue.

Do you know where I can get said cooler?
