Hello all, I just picked up a 1991 964 turbo which is such an amazing car, but I can't fully enjoy it due to the bizarre shifter behavior. The shifter sits on the 1-2 plane, not the 3-4 and there is no easy way to go from 2-3 as the car wants to go 2-1 (Yikes). Also, if I move it past the reverse lockout, it stays there until I push it back to the right. Can someone point me to some areas to attack first? I assume that it needs new bushings or a helper spring. I cannot tell if I can put a SS kit on or a goldenrod because they do not call out turbo models as compatible.

Sorry for the dumb 101 question, but the search function isn't letting me find what I am looking for.

You can use a 964 C2 or 993 Carrera shift kit and or the Goldenrod either will fit , but likely the issue is the shifter tube bushings .

If you can disassemble it it will require removal of the center cover panel from below not sure if removing shift lever from top will get you adequate access .

Once you have the panel removed you will see the various bushings for the shift tube and base of shifter take your pic they are all prone to wear ... Bert

Thanks for the info Budge, will that rectify the revers lockout not returning as well?

this shifter is a tube that is put in two rubber rings. one they fail (and they do ne time) the shifter is a nightmare. if you start there (two rubber bushings) the chance everythig goes well is near 100%
if there is an issue left it is easy to point out.

If my memory serves me correctly, the shift coupling is the most ancient, low-quality part on the car. It's definitely similar to a coupling for a G-body.
Usually the bakelite bushing cracks and needs to be replaced. I'd look at that before buying a Goldenrod, but they are an improvement.

I was most directly referring to part number (26 )in the diagram I know there are two on 993 , pretty certain 964 also have two , in addition

there is a cup that fits part (15) shift rod and that also has a way of disentegrating over the years ...Bert

You guys are the best, thanks for all the help.

Forgot about (15) Budge.
As for (26), I replaced those when I went to the factory short shift. While the short shift guide bulkheads bolt-on for the '92- up cars, on a '91, the body sheet metal in that area has to be laid out and cut as the assembly must move up one whole diameter to accommodate the shifter itself. It didn't take long to do but it's always a nervous time when you are cutting on your car. I made my own Goldenrod at the same time.

Well, some late night youtube videos led me down a rabbit hole to buy a Numeric SSK with the adjustable goldenrod. I will let everyone know how it goes in and drives after.

You can get away with just the numeric and no goldenrod. Practically no difference IMO adding the golden rod with the numeric assuming the bushings to the trans are good. I have installed them both ways.

Numeric is in, very easy install and the piece is just so beautiful that I didn't want to put a shift boot over it. Shifter tube bushings looked to be 7,455 years old. My only gripe with Numeric is that the whole mechanism is about 2MM too big for the shifter opening and needed a ton of fiddling to get it in. Also I purchased a Goldenrod from them and they sent me one that looked like it fell off of a plane at 30,000 feet.

Thanks for all of the help!

Nice,

any Pictures?

I’ll post some shortly. Final question on this, the shifter still does not revert back to the 3/4 plane and kinda sticks in the reverse and 1/2 plane until I nudge it. Any ideas? I don’t understand the transmission well enough to diagnose the next steps to fixing that.

I installed the numeric into two different cars. The later tubs appear to have a relief on the left side of the opening making it an easy drop in install the earlier tub I had to work at so I believe 92 on will be easier than 90-91.
