What temps are you guys seeing on your trans in normal street driving? I just today set the DIC to performance and scrolled through and noticed my trans temp doesn't come off 100 degrees (which is the starting point of the gauge). It is in the high 30s today. Water and oil temp came up to normal running temps. Bad sending unit? Or an incredibly efficient trans cooler? I would have thought even at today's temps it would be > 100 degrees

Thanks!

I have to really get on my SS hard and be banging up and down thru the gears and getting to higher RPMs to get my transmission temp to ever tread over 100F. I think it is just a very good cooling system and that high temps aren't at all generated in normal driving.

Mine doesn't come off 100 in normal driving.

That's about right for normal driving. Even on track, mine barely got up to 154 degrees.

Mine goes up to 130 if I downshift a lot. Otherwise it stays at 100.

Thanks! Good to know.

You've got almost all the same coolers as the ZL1, including all the transmission coolers... you're all good... it's over engineered to take a severe beating on the track... it won't break a sweat on the street.

It went up to 56 degrees here today! I saw the gauge go to about 110 degrees so it works

Wow, that is good to hear on the cooling ability. I can't wait to get out on course!

Max trans temps I saw according to the PDR was 189 after 10-11 laps on a 75 degree day. Out lap trans temp was 135 for reference.

Side note... the circular water temp gauge at the top of the cluster is really a dummy gauge. It never moved from it's normal spot for daily driving, but the PDR data shows max temp of 216. Out lap for that was 192 for reference. Crazy how good the cooling system is.

In normal driving mine doesn't start to register anything until outside temps are above 85 degrees, and then it's only like 110-120. I know mine's an A8 and your's are M6's but I would think the trans cooler is doing it's job either way . I thought I had an issue with mine but then summer came along last yr. and it started reading temps but only on the way home from work.

Following up here on my old 6th gen and my new 1le it was usually around 100 unless busting it but I recently changed trans fluid to redline d4 atf and did the weird pump some out at the end to not overfill and now its routinely 120-130? Anyone seen this?

Well understand that the trans fluid on either a 1LE is used to cool the rear diff. There is a heat exchanger that has the diff lube on one side, and the trans fluid on the other. When it is cool out, that thicker gear lube takes a lot to get warm, so it cools the trans fluid.

However, if pushing the car and the diff is doing a lot of work, it will raise the trans fluid temp significantly. However since it is ATF, it can take a lot of heat.

I didn't know that. (No pun intended)
