From everything I gathered and after reading transmission temps, we came to the conclusion of a failing temp/revolution sensor. Fluid was not low, clutch pack and clutches showed no signs of warp or excessive heat/friction outside of normal range. A good starting point would be to look at the the DCT thermostat and address if that is failing as Bimmerworld states that is a very potential culprit as well : https://www.bimmerworld.com/Cooling/Oil-Coolers/DCT-Transmission-Oil-Thermostat-E9X-M3-DCT.html

I'm wondering, is there a way to bypass the DCT fluid thermostat? To have it permanently open so that fluid flows to DCT cooler 100% of the time. I live in a hot climate so warming up the DCT fluid is not so important.

Foolish IMO. The thermostatic control is desirable. It's easy to access, easy to replace, not an expensive part. Retain it.

They quoted 2k usd to drop the box and replace the sensor and while in there one of the hoses to sort a tiny leak. Might be my next action but will try a adaptation reset for the fun of it first. Again box have done 40k calm miles so continue to refuse to believe the clutches actually slip. |
