Default 12 STI - Tough to grab 2nd when launching into a turn

So, I have no problem downshifting to 2nd when entering a corner, but coming from a stop, more or less launching while making a right hand turn, I have a heck of a time getting into second gear. I have group N transmission mount, Kartboy pitch mount...nothing should be shifting around much. Any ideas?

Do you have one of these? If yes, replace with stock and report back your findings.

Was it doing this before u installed the group N tranny and pitch stop mount. If I were u I would do the engine mounts also, u could be putting the load under wot through the rest of your drive train and the torsion could be causing a binding issue. Would also consider upgrading the rest of your bushings

Before you do anything do #2, ask me how I know.

Trust me. I've done all the bushings. I went group N for transmission mount, crossmember, and rear shifter bushing. I ordered the car with the STI short shifter (which comes with the front bushing). I've done kartboy pitch mount, aluminum carrier bushings, and all the whiteline rear bushings. STIs come with group N equivalent engine mounts. I did all this before break in was over...heh...so I don't know if it would have done it before. My bad.

Should I upgrade the front and rear shifter bushings from group N to kartboy poly?

Yes wouldn't be a bad idea to do the linkage bushings. I have a feeling when the dealer or who ever installed your sti short shifter might have over tightened the shifter linkage bolts.

Reading comprehension lacks here, what I am trying to tell you is if you have a linkage rear mount stiffer than the stock, i.e., KB, get rid of it and go back to stock.

Why would I want to go back to stock? Wouldn't stiffer be better for this type of issue?

And could I have overtightened the linkage when I put it together (had to be loosened when I installed the rear shifter bushing)? I'm just perplexed why it would only affect shifting during a quick takeoff around a corner.

i think hes trying to tell you stiffer isnt always better. in fact because of it being "too stiff" its causing a binding issue, not allowing you to grab 2nd easily.

It also seems to me that he knows this will fix it from personal experience...you should probably listen to him....

its only a 20minute swap at that

edit* also when you are shifting in a turn you are putting a lot of normal force (perpendicular) to the direction of travel.
first off this is going to play a part in the ease of mechanical levers moving around such as shift linkage.
second off, why are you launching into a turn? why are you shifting in a turn? your supposed to wait until you exit the turn to shift. perhaps you should re-visit some proper riving techniques, and this issue can be avoided all together

^Exactly, I was almost to the point of replacing synchros due to the inability of engaging 2nd during high rpm launches at the dragstrip. It was very frustating, I was not able to gate 2nd due to a spongy resistance, going back to stock fixed the issue.

Loosen the driveshaft 14mm bolts next the rear mount, this will allow for room to remove the mount. When replacing the mount back to stock use white lithium "grease", not spray.

I have the exact same setup as u besides the aluminum hanger bushings with KB rear bushing with no issues ever. When I installed it I over tighten the front linkage bushing and was very stiff to shift gears so I loosened it off a bit. Plus hope u used lots of bushing grease when u installed the rear bushing and also there is a chance u might gotten the wrong bushing.

See if that works by backing off the front linkage bolt and if still persist put the stock one back in and if that fixes it then there is a chance u got the wrong rear bushing.

The corners have nothing to do with it, launch the car at 5K rpm and upshift quick to 2nd, you will experience the same issue.

Sounds like an install issue. There are tons of people that run shifter bushings without problems.

yeah....im leanin toward this as an issue

ive had that bushing replaced with a non stock one in both my wrx's and never have had any issue with second gear or any other gear

id bet that some other part of the linkage is bound up and futzing with that rear bushind temporarily fixed it

I have no issues either as long as I am shifting normally, OP states on #1 "more or less launching" this is when problem arises, high rpm quick launch, the mount grabs the shifter rod tightly causing 2nd gear to bind. During normal shifting the shifter rod slides/pivots in the mount cavity without a problem as it is easier to overcome friction during a slow controlled shift.

I will try to backup this info with video.

I actually have a similar problem my FXT, where sometimes 1st or 2nd will "stick." I suspect that those cars have particular problems with this sort of thing because the stock engine/trans mounts are soft and the whole driveline mounts a bit lower in relation to the body, so the angles in the shift linkage are even more severe. So, when the engine and transmission twist around during a hard launch or hard acceleration in the lower gears, things are even more likely to stick and bind.

So far, I've tried replacing various linkage and stay bushings with poly (and making sure to lube the bushings well). It's helped a little, but I think I'll try putting stiffer mounts in next to see whether that gets rid of the rest of it. Twisting and binding in the shifter stay and shift linkage should only happen if the engine and trans are moving in relation to the body, after all...

^ And perhaps this is more prevalent on FXTs as #16 states. The truth is mine is no longer binding after going back to stock.

As I have mentioned having the same setup as the op with no issues under wot running through the gears and actually miss 5th gear more than anything cuz of the POWA lol/

I think its more of an installment issue or wrong bushing.

YOU beat the snot outta the car at the race track for a month before you had any issue

the bushing is stationary....the rest of the linkage is NOT

YOU have/had another issue....that rear bushing had nothing to do with the issue...but your ****ing with it DID

Yes, I had it for a month prior to the issue with 2nd gear but that was in the middle of summer, aka thermal expansion, and plenty of fresh lube.

Maybe I'm doing something wrong. I can launch from a straight line no problem, but sometimes, especially after I have been driving for a while, when I take off from like a 90 degree turn, and wind out 1st gear, 2nd gear is hard to grab. Almost like something is moving while I am winding the car out, and the combined movement of the drivetrain is making it hard to get it into gear.

Maybe a little more finesse while shifting in 2nd its not a honda lol jk.

Doing a 90 degree turn in 1st wot trying to hit 2nd u should be facing the opposite way by the time u go to shift into 2nd/confused:/

I would consider doing a full bushing kit to stiffen things up, don't forget when u stiffen one part up the torsion and strain is going travel to different parts of the drivetrain
