High rev gear change
by minijrocks » Thu Jun 30, 2005 2:22 pm
It was a little wet the other day and i was coming pulling out onto a road heading upwards, and it spun up to like 7500-8000 rpm and i went to change fast to 2nd and it wouldn't let me .

TPPS. Generally enabled from the factory but for certain drivers only.
Toyota Pillock Prevention System.
If you were able to semi match the RPM to the gear then you wouldnt have any trouble shifting. Trouble is, the higher the RPM the more critical the RPM match for the next gear.

gears

That is common in most gearboxes and refered to as balking (spelling?) standard synchros just cant handle the revs and the speed at which your trying to shift.
Some gearbox builders have been known to cut small grooves into the synchro rings which give the gear oil a way to squeeze out of the ring faster (as its often the oil that stops the synchro engaging) and allows quick changes.
In reallity you just need to slow down the gearshift but dont be scared to use the rev limiter
