So I drove my car for about 30-40 minutes and it was warm before that... and my transmission fluid temps are reading below 100.... like not even registering... is that normal?

I should add that it’s 46 degrees here in Kansas...

Unless you do a fairly long Interstate stint, it might never show more than 100F. The trans cooler on the SS is substantial. On the track on a 90F day, I don't recall ever seeing more than 199F at the end of a 30 minute session. That's no big deal.

In other words, the trans cooler is sized for endurance racing, and is total overkill for 60 MPH cruise control in winter.

Good to know.. just had a lot of work done to her and nicer noticed the temps for the trans fluid being low as I read operating temps are roughly 175... I just keep blowing my BCM3 fuse a lot when it’s super cold out..

Any ideas why?? Had a stage 1 cam, oil cooler, kooks long tube headers..and a tune of course... seems like when it’s really cold out and I start it or when I leave before the trans fluid temps read the slightest movements it blows.

Wait, I just noticed in your pictures you have an automatic trans. My comments were 6MT based.

Sounds like you need to investigate why your fuses are blowing; perhaps a discussion with your tuner regarding what settings they changed?

Once the cold weather sets don't expect to see much for that reading.

The A8 and I bet the A10 use a thermostat in the transmission to regulate the fluid temps. The A8 should get warmed up just fine in a short amount of time. You have other issues if yours wont warm up and you keep blowing the BCM3 fuse.

I'm popping bcm3 every time I use right turn signal.. it knocks out drl passenger lower drl driver and rear driver running light.. no idea why.. starter is beginning to give I know that..
