fordman67 is right. i work work on class 8 over the road trucks and they all have transmission coolers even though they are 10 speed standard transmissions. they achieve this by machining a inlet that sits very close to and matches the curve of a gear on the right side counter shaft. the closeness of the inlet to the gear and the centrifugal force of the oil being slung off the gear forces it through the lines and cooler.

I talked with an engineer a while back about this stuff. He basically said why worry about it as such low temperatures. I said 200° is low temp? He said yup, for gears that's nothing, and the oil is designed to deal with it.
He recommended a clear anodized finish on the cover as that particular coating offers the most heat dissipation. I have sold about a dozen anodized covers over the past 4 or 5 years, but I can't say that I have any hard evidence of helping heat.
Why do the cover at all? For us, steel covers last a few years with our super special custom salt/brine winter road treatment. An anodized cover with ss bolts looks almost as good as new 5 years later (on my own truck anyway.)
