Short Shifters...is this true?

[ghetto waggon]

"Do understand that setting too short of a throw can destroy your gear synchronizers much faster. Short shifters makes shifting much faster, but at a toll of the gear synchronizers. Remember to shift softly with some finesse!"

??????

If that is the case, the stealership could definetly argue that something that potentially damages the synchros voids the warranty.

Does anyone have any additional info ?

 

[ForceFed]

I don't know about that one??If you aren't grinding gears than you should be ok.Now an in experienced driver with a short throw could be dangerous!

Whether you have a short shift kit or not they're prolly going to hassle you saying that your shifting patterns are what caused the problem...whatever that problem may be that is affected by a short-shift kit.

B.S. Does not affect the transmisson. The throw from the bottom of the linkage to the transmission is the same. The throw to the drivers is shorter. Duh.

I said the same thing to the tech when my P5 was in for service and, after a short road test, he had mentioned the warranty could be voided if I did not remove the B&M :bs:

Short shifter's shouldn't cause serious damage unless you are rough on transmissions to begin with. I've got 43K on my protege and have had the B&M shifter since the first month I bought it and the tranny is fine. My old RX-7 had over 140K on it with a short shifter...again no problems.

My Dealership installed the Kartboy short shifter and bushings. They said no problem. I hope it's not a problem. As someone else said the short shifter only changes the throw to the driver. at least that's my understanding of the system.

Why'd you take it to the dealer for a short shifter? It's almost the eaisest thing you can do yourself. Couple screws, couple bolts, and a snap ring.

Rev Matching

If you want to prolong the life of your transmission try rev matching. I got into the habit when I had my RX-7 a while back and so now instead of slamming into gear I'm at least within the RPM range of my next shift.

(lol) funniest thing i've ever read... the mech must be on crack or something... lolz... "could be voided"??? err.. it's either voided or not... no?? hahaha...

Giving it some thought...

I was thinking about something I find interesting :

What may cause certain damage to the synchros may actually be leaving your hand on the shifter for more than the necessary just to shift between gears...

I thought about this,,, If with a regular shifter you move along a larger arc (longer shifting distance to your hand), and with a short shift kit your arc is reduced so you "shift shorter", but still in both cases the action below the pivot point is the same (it should be that way I think!), then if you leave your hand on the gearshift knob in a stock configuration, the effort made on the shift bar -that at the same time acts on the trans- will be less than the same hand-on-the-knob situation in a short shift kit.

So I figured leaving your hand in the gearshift knob longer than really necessary could eventually damage the trans to some extent...

Well, I don't see many race-car drivers taking the steering wheel with just one hand...

Or maybe I just have too much time right now to think about such thing... guess I'll leave it like that!, I have to catch a plane!.

Later,
FEDE.

Actually, with a short shifter resting your hand on the shifter would put less force on it due to the decreased lever, as opposed to the longer lever. Think of it this way, long lever=less force required to shift. Short lever=more force required to shift.

So....If you applied equal force to each lever (resting your hand) you would get an output of force greater with the stock lever.

Ya follow? I don't think I explained that well....

This is good advice that you don't see people talking about around here often. Downshifting and double-clutching are two things that can add tons of life to your transmission.

I have to rev match the P5 when I downshift otherwise its just too uncomfortable.

Qwitcherbitchin' !

Lets....figure out the answer isntead of fighting!

The quote came from the site everyone is pulling the TSB's off of, so I'd claim it to be at least somewhat reliable. The other info on the site was pretty useful to me to boot.

Tom@karboy, any words?

Red Baron, what happened with your little ultimatem to take it off?

 

[ghetto waggon]

**I think it might make sense, that if the throw is much shorter, and you do ride your hand on the shifter, that the same amount of pressure in one direction with the SS would be, eh 40-50% more than on the OEM shifter?

just for looks

sure i know that a short shifter will improve performance, but i think it'll look a whole lot better then the stock shifter..this is one reason why i wanted it..i just started driving a manual car 2 weeks ago and i was thinking about getting a B&M short shifter. now after reading what everyone had to say, i am wondering if it's worth it. i am still in-experienced and i don't want to mess up the trans. what do you think?

The B&M is still on the car...I have not seen that :bs: tech again...he was fired . Thanks for asking.

My opinion :

Good : quicker shifts, shorter throws, very precise, great feedback

Bad : more effort is needed to change gears

I've had manual transmission cars since 1984, and if I had know about short shifters before last year I would have had them in ALL my cars. Best thing I did on the P5. I have driven F1600 race cars and the shift feeling you get with a shorty in your everyday car is very close to what you get in the race car (they are WAY much closer but the mechanical feeling is very similar).

Jophus14 : go for it.
