Transmission cooler for manual

[crazybiker]

I was just wondering if anyone around here has put a transmission cooler on a manual, or if it's even possible, because I took the car for a very long drive through the mountains last night, probably about 20 minutes worth, and by the end of it, there was just a slight rattle in the gearbox which led me to believe that the gearbox oil was slightly warmer than optimum and was a bit thinner than I'd hope.

The thing is, after 5 minutes or just idling down and 10 minutes or so with the car off, when I started back up again, it was perfect.

How long has it been since you changed the gearbox oil? Might be time.

A manual gearbox doesn't run a pump so you can't fit a cooler unless you have an external pump. Running an external pump would also pressurize the gearbox a bit and you may start having leaking issues. Oil supply would be an issue too, gearbox oil is fairly thick so moving it around through a pump and a cooler would be a problem.

Yes, it is possible.
You need 2 ports on the box, one in, one out, a pump a heat exchanger and somewhere to mount it.
I've seen small thermo fans on heat exchangers mounted parallel to the floor, they work well.

Hmm...Gearbox oil was last changed I think about 12-14k ago. Not sure exactly.

The t5's run ATF DexIII so its thin enough to have a small pump and run it through a cooler. Only other thing is to run a slightly thicker oil and see how that goes.

It's got slightly thicker oil in it now.

Not all of them do.
