How hot does YOUR shaft get?

Just a curious thought? I have noticed my stick/gear shift shaft gets really quite hot during a drive. . .is that normal? How hot should the shaft be? Or should it even be hot at all?

It's connected directly to the transmission. Sending power through gears and bearings causes heat in the gears and bearings due to friction, this heats up the case and the fluid. Having the exhaust right next to the trans doesn't make things happier.

Mine gets "plenty warm" but I haven't burned myself on it yet.

FBDrifter, replace the rubbers beneath the boot with new pieces and you'll be surprised when no heat wafts up from the boot...I hated that obvious hole down there "somewhere" letting heat in and got rid of it that way.

Even replacing a rubber and a having boot my shifter gets quite warm (almost hot).

I find that the warmest spot is where my right leg rests on the transmission tunnel. My shifter is usually warm, but not hot by any means.

I had a MOMO aluminum shift **** for awhile and it did get rather warm to the touch.

If yours is HOT, might be a good idea to replace the trans fluid with Redline MT-90. Your trans might be low on fluid.

I've got a walnut Mazda **** that has basically followed me from car to car...the rubber stuff prevents the hot air coming from the shifter boot. A plastic spacer inside the ****, plus the fact that it's actually wood, means I never have to worry about gripping it...I should have mentioned that since this thread is about the shaft and not annoying leaks from the trans tunnel...

Bayce is referring to the heat emonated from trans to the gear shaft, not a gap causing hot air to rise.
