Downhill Downshifting

If you downshift at the wrong time though, there goes your tranny! lol Anywa on a downhill it puts more pressure on the tranny thats why the early 07 yaris stalls out when downshifting downhills. I heard about it from a friend who had a yaris.

shoot..for the thing to stall out like that I would imagine it would have been red-lining or beyond for sure upon downshifting...

As far as manuals go, most of the time 4th or 5th gear is still okay on long gradual downhills...it acts like a brake, doesn't sustain high RPM's (which won't mess with your tranny) and you use the brakes ever so often...and if it happens to be steep enough to downshift into a lower gear (like 2nd) than you are most likely not going fast enough to worry about the brakes as much...just "pump" em rather than hold em down for long periods of time.

And what kinda sustained RPM's are we talking about as far as "wrecking" the tranny?

I dunno...just my thoughts...
