I have read that a short shifter is bad for your tranny, something about how it messes up the syncros and can even break teeth off the gears.

Is this true?

Any other opinions or comments?

Thanks

When i had my B&M SS it sure felt like it was raping my tranny...It wouldnt engage smoothly and i felt like i had to force it into gear through the synchros....I know its supposed to take more effort, but every other car i've driven felt fine when they had a short shifter, but my P5 felt like i was raping the crap out of the tranny...

They wear out the synchros due to the quicker shifting. The brass rings don't have time to work properly or something. I don't know exactly how it happens. I've heard that 1-2 synchro wear out faster than the rest though.

I don't know...but I have been running my B&M short shifter in my car for a year now....I have NO tranny problems what so ever....no grinding....no problem getting into any gear....everything works just like it is designed to.

Hi Yuri,

We have never heard that before. Generally any damage is caused by the operator. This usually occurs when the driver has an aggressive shifting habit or races the vehicle often.

Damage that we have seen has been at the shifter. Please keep in mind that most short shifter kits are of a good quality but if you shift aggressively every weekend for 52 weeks...its going to wear out.

As for the transmission...we have never heard of a tranny being damaged by a short shifter.

Brian

i had a friend who had one on his Si and it messed up his car bad now we dont know if it was the short shifter or his driving though

what i could imagine is:

due to the fact, that shifting works quicker (since the ***** moves faster because of the gained length of the lower part of the rod (pls excuse this poor vocabulary)) you will have to change your shifting habits...

shifting the same speed/intense would be like "superhard&superhardfast"shifting with a normal shifter...which is not good indeed.....for 1st/2nd/rear....since we have no racing transmissions we might get problems indeed.

(that is also why mazdaspeed was right when they said "Generally any damage is caused by the operator. This usually occurs when the driver has an aggressive shifting
habit or races the vehicle often."

maybe changing the transmission fluid could support the transmission to compensate a little of your shifting "misbehavior")

i now got a reply from kartboy and the tenor is the same...
"here should be no reason that the shifter would cause
anything in the transmission to wear out. All we are
doing is changing the mechanical advantage, thus
making you input a greater force at a shorter length,
and a shorter throw. The force into the transmission
will be the same, unless you purposely abuse the
transmission. There would be a good correlation
between the type of person who would add a short
shifter, and their tendency to abuse the transmission.
Far more damage would accur by dropping the clutch
and speed shifting. Both things I would do, but would
hurt the transmission whether you have a short lever
or not. "
