Default Hard to downshift to first, ne one else???

Basically when driving local and coasting thru an intersection I usually downshift to first so that I can just go if I see no cars coming my way. But in the STi it feels like there's some resistance when going back to first going less than 5 mph. Without forcing the issue I usually just release the clutch and press it back down and try again, but still theres some resistance. Once I come to a complete stop tho it shifts smoothly into first. So is this normal???

Also I tried searching the archives but all I find is people with wrx's that say they also have this problem. I mean it's kinda annoying and I'm thinkg about bringing it back to the dealer to have it looked at.

thanks in advance

Wes

try rev matching b/c even though you're only going 5-10 mph, all the parts of your tranny are rotating at different speeds. It's hard to get into gear b/c the synchro's are doing their job but it takes time, especially when going slow. You can also try double clutching. My accord and my dad's audi do this sometimes.

My box shifts great & after I beat on it last weekend at
my local autox, it seems to shift even better & the engine
feels stronger.! How many miles do you have on it? My box
was kinda notchy for the first 700-1000 miles & then I switched
to Mobil 1 75W90 gear oil & things felt much better.

I only have 200 miles on mine so far. Maybe it needs some time to loosen up I guess.

Every single manual transmission I have had has felt notchy at first and smooths out after several thousand miles, this is totally normal and you just need to give it some time. Once broken in the resistance shifting into 1st is totally normal, not being able to shift or grinding into 1st under 15mph is not normal and should be checked out.

Mazdman, you might want to search by my username in the Transmission forums regarding my recent issues using Mobile 1 synthetic transmission fluid. I realize the transmission in the STi is not the same as the standard WRX but I would still have very strong hesitations using Mobile 1 on just about any transmission after my ugly experience. I doubt you'll see any problems at first with the syncros being brand new on your car but once they start to wear it's anybody's guess at this point. I know that people with newer transmissions <30k switching to Mobile 1 reported no problems but you'll find several other threads describing problems much like mine when switched to Mobile 1 around =/>30k. I don't want to alarm you further but I couldn't flush the Mobile 1 out of the tranny/syncros despite multiple gear oil flushes up until the transmission was broken apart and fully cleaned with brake cleaner. The syncros did show some wear when the transmission was pulled but with that in mind everything worked perfectly up until the point where I switched from OEM fluids to Mobile 1.

I'd like to hear more about your issues w/ Mobil 1 gear oil.
I assume your referring to the fully synthetic GL-5 grade. I
normally use Redline MT-90 when a GL-4 75W90 is called for
in a tranny & Redline 75W90 gear oil in diffs where a GL-5 is
called for. The problem w/ the STi is that the front diff & gear
box share the same oil. Therefore, ideally I would have used
Redline 75W90NS which is not as slippery as the 75W90 which
can cause gear clash due to the low coefficient of friction.

I have used Mobil 1 gear oil in several other high performance
cars gear boxes for many thousands of miles w/o any problems.

I would think that if you can prove the cause of failure was the
use of Mobil 1 gear oil of the proper viscosity & rating , then
they should pay fully for all repairs.

Sorry pet peeve of mine...If the intersection has a stop sign, stop the car. Don't just cruise thru if no one is coming w/o stopping.
(ok, I'm done!)
If you are deciding to place the car in 1st gear "on a roll" just lightly tap the gas with the clutch in, position the gear towards 1st and when the revs match the tranny it'll slip right in.
BTW: 2 people have slammed into me coasting through an intersection where they had a stop sign and I did not stop. It was decades ago, but I swore the next time it happened I'd be heading for jail for assault on the other driver.

I'm not trying to say that the Mobile 1 caused the problem but to simply put it the Mobile 1 degraded the function of the syncros as they require a certain amount of friction to operate correctly. I'm not going to go into a debate in this thread as there are several threads covering this to death and I think you'll find more people having problems using Mobile 1 than not.

I was lucky as I have a very-very-very mod friendly service department and they replaced all of my syncros everything under warrently on a Stage 2 car.

Your problem is normal. Try double-clutching: as you come up to the sign, put the clutch in, shift to neutral, let the clutch out. Just as you are almost stopped, put the clutch back in, blip the gas, and push the shifter into 1st gently.

Or you could just do what I do and leave the car in 2nd. You have plenty of torque so if you are not stopping anyway there is no need to downshift.

Listen to the rev-match and double clutch info you are getting. But seriously, I have yet to come into a traffic situation where downshifting to 1st in a STi is necessary at any speed over maybe 3mph, maybe desireable, but not necessary. Unlike the WRX that I had, the STi has enough lowend torque in 2nd to do 99% of the traffic jobs needed.

I never said I do that at stop signs, would never not come to a complete stop for fear of points on my license. I'm talking about four way intersections where I slow down for fear some punk is gonna side swipe me so I check out both sides first.

Ne ways I'll try rev-matching the downshift and see if that helps. THanks for all the tips, put my mind at ease.

Rev-matching will help but double-clutching is more important (at least in the WRX).

The other thing you can try is to shift down into 2nd and leave the clutch in. If the coast is clear as you come up to the sign, rev up and let the clutch back out (still in 2nd). That's less jerky than leaving the clutch out and hitting the gas at low rpm.

BTW, nobody where I live ever comes to a complete stop at stop signs unless they can't see clearly. If you can see clearly up and down the cross street as you come up to the sign, there is really no safety issue with not coming to a complete stop.

it is normal for subies to not let you shift into 1st when rolling. usually around 3mph, you can slide it in. both of my imprezas are this way. it sucks in my 1.8L impreza because of no torque, but you shouldn't have an issue getting started in 2nd gear from a roll. my 2.5L RS pulls beautifully from 2nd gear.

heyo, 1st post, thought i was already registered.

i just wanted to say how easy clutchless shifting is in the sti for gears 3-6. with 3k on the car i love the tranny. obviously clutchless shifting relies on rev matching. i hope i don't lose the feel for the tranny when i my 7 gets out of the shop.

(btw, totally stock, plat silver, love it)

I just wanted to add that this is exactly the same in my Prelude and a GS-R before that. Sometimes it will drop into 1st nicely, but when I feel that resistence I either slow down a bit more until it drops in, or I double clutch lightly. And on those cars at low speed 2nd gear is really weak. In stop and go traffic 1st is often required from a roll. I am sure the STi has plenty of 2nd gear power, though :-).

For the double clutching, I use Mike Wevrick's technique except I would try blipping the gas before pressing the clutch in again. I think if you do it after, then it is more like rev matching and that doesn't work as consistently for me.
