Hello
when i drive my TII, in 3rd gear and i try to downshift to 2nd, but it seems like there is a door not allowing it. This happens in 4th gear downshifting to 3rd also. I was wondering what is the matter(if any) is with my TII. When I am in 3rd gear, my RPM is around 2000, so downshifting to 2nd should be ok. SOMEONE PLEASE HELP

i almost have had the same issue but mine still works just......
with a center force dual friction clutch and my current Racing beat street clutch .
both have had the MazdaTrix short shifter

I mean, when i try to slow down from 4th to 3rd, sometimes it doesn't work

but sometimes i want to slow down from 3rd to 2nd, and it almost NEVER works

and i was wondering if it is my Transmission or clutch that is causing this. Or am i doing something wrong?

It's called rev-matching, and your synchros don't like it when you do that unless you rev match.

I dont really have that problem but rev matching (tapping the gas to the amount of revs you were at before pushing in the clutch) is a very good idea, less stess on tranny. I do it as a part of my daily driving and performance driving.

throw-out bearing?

just get a new stage one or 2 centerforce clutch, not too expensive, but then i do work at keystone automotive, in the warehouse so i see this stuff all day.

Double-clutch rev-matching is for cars without synchros.
And drifting, for proper control. However... for street driving? Doesn't really make a difference. I don't, and I don't have a problem downshifting.

You don't have to double-clutch. Rev matching is a must if you want your tranny to last. We're not talking about heel and toe here.

It doesn't take extra effort once you learn it...

And a perfectly matched downshift is always hella sweet.

Amen brother.

Keep in mind that if you are down-shifting to slow down, brakes are much cheaper to replace that clutches.

Always try to rev match myself. Still working on perfecting it.

rev matching cause almost no wear on the clutch, where as down shifting does. just something to think about

BlackRx7

The abuse in downshifting is done to the bearings in the tranny as well as stressing your LSD....I just slow down in the same gear I was driving in then, I use the brakes to come to a stop, downshifting is fun but it put alot of abuse to the car, why not leave the launching and accelerating to do the abuse.

Yeah sounds like Syncro's almost. Mine would stop and not go into 2nd from 3rd unless it spun down to a low RPM.

Double clutch/Rev matching rocks.
It not only saves your syncros but you become a better driver.

I use to rev match instinctively even on the newer cars.

I was also wondering... because my clutch FEELS stiffer than others, and when i start my car i have to PRESS DOWN VERY VERY HARD to start and sometimes even then it won't start. my 1st gear is REALLY sensitive, i release the clutch even only .5 inches (a little exagerated) and the first gear is engaged, My sister said that (she has been driving longer than i have on stick, sports cars mind u) the "depth" of the clutch pedal can be changed. make it a little HIGHER so not as sensitive and more "room" for giving gas and releasing the clutch so somewhat less sensitive. Is it because my clutch pedal is so stiff compared to others, that even when i press on the clutch pedal, the clutch disengage less than other cars and so from 3rd to 2nd, its harder to shift and when i do downshift it seems like i didn't step on the clutch all the way?

Sorry, i know its confusing (and somewhat denial maybe....)

^ Your sister is right. While you're there, you might want to check the hydrolics too. There are other things it might be, but check that first. (Other things are more expensive)

I double-clutch on all of my cars. Saves synchro life, and on my 7, the tranny complains a lot less. I do it by habbit now, when I was teaching my girlfriend stick, I kept doing it by accident when I was showing her how to shift.

Calling it 'Rev-Matching' always makes me think of shifting without using the clutch . . .

Cybaster

any experts have any other comments? because i am already stressed out that my 7 eats so much gas =P its hard for me to think that i have to fix another BIG thing =D if the clutch just doesn't open up enough, then its cool. I'll get that fixed right away.

totallimmortal

I have a similar problem its really hard to pull into second when down shifterin, rev matching and double clutching don't seem to help at all, bad synchros maybe?

rev match is a must if you are a competent driver... your synchros will go.. change your trans fluid if you see bronze dust in the fluid<<<<<<

You could have an aftermarket clutch in there...
most heavy duty pressure plates require more out of the hydraulics than the stock plate, and you get a VERY short pedal engagement area in return.

Try adjusting the clutch pedal and see what happens.

Rookie84

If you have an aftermarket clutch, then can you adjust the clutch pedal to allow yourself more engagement area? Mine is like at the very bottom of the pedal travel coz of god damn aftermarket clutch.

wow. lots of bad info here. too much too even list and argue.
anyways, sounds like a) your synchros are dying, or
b)your clutch is not disengaging fully.
most likely, it is a. double clutching will help u out here. double clutching will allow u to shift into any gear no matter how bad your synchros are. i suggest u do some research on double clutching, or u rebuild a tranny that u pick up somewhere. either way, it is a great learning experience.

Cybaster

well for today, every gear i shift into and downshift i've been rev-matching. obviously the ride is smoother =P and if i PRESS on the clutch with ALL MY WEIGHT when i am downshifting into 2nd gear. i can usually get into second gear when i couldn't before but i still hear scraping... so i am leaning more towards the after market clutch theory and should adjust my pedals. but i think i'll looking into the bronze dust also. but basically its like what oregano said? a) bad synchros, b) clutch not disengaging
