DCT Transmission Sluggish in Higher Temps

So maybe he meant close to 2L total.

Yes that. A billet pan adds extra fluid, close to +1L. Banjo bolt allows overfill of +1L. So that's close to +2L of additional fluid compared to stock.

Yep

See posts 367 and 370 here for the proof (the hard data that CSF has I would guess intentional failed to collect and post): https://www.m3post.com/forums/showth...ht=csf&page=10

Thanks! Looks like a comparison of temps from different cars but similar mods, not 100% ideal, but good to have some data none the less. At best it is no better than OEM and worse case it is less effective then OEM. Not a huge drastic change either way.

Would have been better to have a direct comparison on the same car, but even then track and temps can be a variable.

Hopefully, we can find three cars with three different radiators - OEM, CSF, do88 - with AIM devices on the CAN bus.

Now that we can track DCT temperature we will have a bit more empirical data about the DCT cooling.

I will provide do88 temps

Definitely good to have more data, only thing is I've seen cars vary pretty widely in temps vs other cars. Not sure what it is, could be based on maintenance state (Original waterpump, tstat, etc) but I've seen a wide range of temps on cars with stock rad/oil/dct coolers.

I think only warp10 has DCT temp sensor until now. So not sure how you saw DCT temperatures and how it varies among the options available to us.

We all are not professionals with race cars. So it is almost always different setups, tracks, ambient temp.

It is best effort empirical data.

The DCT boss that Mach Snhell sold is what I have. It was from the cold side.

I believe the current DCT temp that's in the aim protocol is from the transmission side.

Do88 DCT radiator and the Slonik DCT pan are a one stop shop to fix this. We could run the stroker 1h at a time at full speed and not run into DCT issues of any kind.

You just look at the DO88 vs every other choice it feels like a no brainer to me. It's not like it's astronomically more expensive either. The only downside is that due to the size it's a lot more exposed.
