GEnts,
can anyone hazard a guess as to what the approx oil temp of a modern 6 speed automatic gearbox should be once it's got up to operating temperature?
Ta.

Information here may be outdated?
Id guess in the 60-90°C range
yes, mine (7 speed flappy-paddle) reads about 90°C though it takes a lot longer to get there than the water temp does.
I *very* much doubt it!
Nope. Sometimes 'shares' the engine coolant when the gearbox oil cooler that is inside the engine coolant rad springs a leak and the two fluids mix. Expensive repair job :-(
Well at a guess I?d say that the desirable properties for an engine oil and a gearbox oil are wildly different. The only time that I know of that it has been shared is in the old BL A-series transverse engines when the gearbox was effectively in the sump.
Oddly, no one else has copied that system.

and the transfer bearing always went
totly stupid
Yup, but that's how they made it!
Agreed. It's going to depend on ambient temperature of course.
Shares the engine oil too?
Why?
Ohhhh DSG.....
