Time to full operating temp for transmission?

Just for comparison, how long does it take for other people's transmission to reach ~90 C / 200 F on normal (not towing), nonstop highway driving in 8th gear during warm weather?

I'd peg mine at ~45 minutes. I haven't collected scientific data to corroborate it, but I think my fuel economy improves once the temp gets up there.

Obviously, the oil temp rises much faster.

Whilst I haven't set a stop watch, I think that would be about right.
And much faster towing, which is understandable.

Cheers

That's about what I'd say. Highway driving in 8th with the TC locked puts very little heat into the ATF.

On my 40 mile, 50 minute commute (when I have to drive it) doesn't completely heat the ATF to operating temp in the 190's. If traffic is bad and it has to do a lot of shifting, it gets up there a lot more quickly.

Re: Time to full operating temp for transmission?

Yup, sounds about right. It's too bad we don't have the "thermal management system" that the Ram 1500 utilizes ,ie thermostatically controlled engine coolant lines that run through the transmission. During cold weather operation the transmission will warm up much faster than with passive heating only. This can result in less wear and a claimed fuel efficiency improvement of up to 1.7%.
