Did a bit of a search on the GT2/GT3 section and couldn't find specific info that answered this.

My 997.1 GT3 has approx 15,000 miles, and has had a very notchy 1st and 2nd gear engagement, even once the car is warmed up. Am aware that GT3's are really supposed to have a notchy feel, but i've had the car since new, and it didn't feel this notchy. Now a couple of points to make:

• warming it up doesn't make much of a difference;
• there's no actual "grinding"-- as if a synchro were going out. More like, it's just more difficult to get into 1st from Neutral and into 2nd from 1st, than it used to be;
• i used to track the car a lot, but have never drag launched it, and don't recall ever having a bad miss-shift;
• the motor has been out a few times early on (to fix the pesky RMS). i understand this could be significant information explaining why the shifter feels as it does

it COULD be the clutch needing replacing, or a synchro going bad... but considering the mileage is relatively low, and the transmission has neither been abused with launches, or suffered misshifts, i'm thinking (hoping) it's not the clutch.

i also plan to have the transmission fluid checked/replaced.

But i keep coming across the shifter cable adjustment, and am wondering: have people actually experienced an improvement in shifter feel only with the cable adjustment?

Thanks in advance!

YMMV but mine got noticeably better after changing transmission fluid (Delvac 75W-90) and adjusting the shifter cables.

Coming from the world of non-synchro, spur gear trannys, with multiple disc clutch ('23 Lincoln)........ Sitting at a stop, with the clutch in, going into first gear should be effortless, unless the clutch is not fully releasing. Additionally, when the gear oil is cold, revving the engine a little higher and shifting faster into 2nd gear will allow for a smooth shift. As the oil warms, less revving and a delayed shift should also allow for a smooth shift. I have found this to work on my 12k mile RS. Maybe I'm nuts for a "dated" comparison but gear oil becomes more liquid, as engine oil does, when it warms up. As last resort, try double clutching on upshift and see if that helps. Additionally, just as you almost come to a stop, depress the clutch and shift back into first which should also be smooth as engine speed and vehicle travel should be a perfect match, Can't answer the "cable" question but car doesn't have to be up in the air to try the above........... My "dated" 2 cents.

I would definitely consider having the motor and trans mounts checked. As these cars Are 10+ y/o the rubber will be pretty wasted

Thanks. anybody know anything else about this? my mechanic also suggested I look into that

there are no "shifter bushings" to replace. There is the shift console. You can try that. Doubtful though. If you replace get the 996 CUP version or 997.2 RS version. Both have metal bushings and are more durable.

thanks for the tip!
