My SC has a Wevo on the 915 and it shifts OK on the street, except for the 3rd. Same as Justin, I either pause on neutral or double clutch it to avoid grinding. But on the track it really gets worse as I shift in high revs the 3rd really screams. so I lgive up some track time to shift it smoothly and with finesse (as Ross Bentley writes) .My car has 185K and the gearbox was rebuilt at 135K. My clutch is extremely low too.

Knew my '82 needed some work on its 915 when I did the PPI, particularly the 1-2 synchro. After I first got it, I was really frustrated by the shifting, had to pause hard between gears and really walk it in, always a struggle to get it back in first. Finally broke down and got it in to the shop, replaced all the synchros, and a bunch of other trans and clutch work. Amazing difference, it was like a different car, now I absolutely love it, even in traffic its works great.

As all have said, a good 915 w/ healthy synchros & clutch that have all been properly adjusted shifts beautifully. BUT BUT BUT, it will never shift or feel like a modern tranny, "modern" as defined by even a 1989 Accord. A 915 trans is just a different animal, and you've got to understand that from the get-go. So if you're ok with it and no one else will drive it, (or are lucky enough to have a signif other that IS gear-savvy), then you're good to go. The add'l plus is they are lighter and cheaper to fix/rebuild than a G50. You kind of have to have your "915 head" when driving it ...which is cool because you then become part of an elite club who actually knows how to shift this antiquated race car with finesse. ![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)
Drive more 911s until you find a fine-shifting 915. Only then should you compare to a G50-clad carrera to determine which suits you better. IMHO anyway![Big Grin](https://rennlist.com/forums/images/smilies/biggrin.gif)

Great input everyone. The 915 was on a beat down grey market '85 coupe that was sitting on a lot just before I had a meeting so I gave it a wirl. I will not let it stop me so it looks like my search will now include 915s.

When the 915 tranny was new and a few years old it was a terrific transmission. I suspect an abusing owner in the past is the reason for your problems. It was one bullet-proof tranny.

If your shift lever is 'swimming' or you're 'searching' for a gear, have the bushings checked under the shift lever, and at the coupler behind the seats. Changing these on my wife's 901 trans made a WORLD of difference in her '69. Combined with the trans rebuild her 901 shifts like a dream. Same is true of my SC 915.
How difficult is it to replace these bushings and is there a DIY section somewhere on this ? Tx.
