But from 3rd at, what, 4500 to 6th at 2500? That's a lot time to squeeze all the lube from between the cones and get 'em cookin' real good.

It's not bad at low speeds because the relative speeds all converge to zero RPM.

It's that 6th-to-3rd shift at highway speed that'll cook the 3rd gear synchro in no time. Those I ALWAYS double-clutch.
