Hi again. I'm wonder how I can identify my 5-speed gearbox, and if anyone have any idea why I have so much slack in my gear stick. It seems like the problem is inside the box, as I can rotate the "pin" going in to the gearbox quite a lot. And the changes are very imprecise and pretty hard.

RonnyÅ

Some times if I try to be quick, the stick could even lock up on me, and it won't select any gears before I fiddle a bit with it.

Sounds more like the rear shift coupler and/or front shift ball socket are worn.
They are part of the odd shift linkage on top of the torque tube.
Did you check them for slop?

Transaxle has a stamping beneath. It faces the road surface. Post that number, we can reference it.


Do you have the workshop manuals and special documentation CD from 928's R Us? That CD is loaded with workshop manuals, wiring and other special tech literature.

RonnyÅ

I don't have the cd, and yes I would check the number later and post it.

Regarding the shifter I KNOW its the straight pin going in to the gearbox, as I also had trouble with the coupler jumping of. Then I found out that I could rotate the straight pin probably around 90 degrees in total, by hand without any force. I guess it shouldn't be like that? With help from a friend I could se that this was the same slack you feel when wobbling the shifter from side to side in neutral. Probably not that good explained, as I'm Norwegian and not English or American. Hehe

Well, the coupler is pinned to the input shaft with a small allen-headed set screw.

Does that have sloppyness? Where the coupler is supposed to connect to the shaft? Is it loose?


Respect, btw, for you and others who speak multiple languages.

It was sloppy and bad, yes. That was why it kept falling of. I made a new one from a normal bolt with some help from an angle grinder ;-)

But the slack problem was in the pin itself, felt by hand without the shifter attached. So it must be some problem inside the gearbox.
I know that on some gearboxes you have some kind of springs witch takes some slack from the shifting. Maby there could be something like that on the 928, witch in this case probably are broken or have detached?

I second Landseers comments. The "pin" as you describe it is held in place to the rear shift coupler via an allen head grub screw. If you can turn the rear rod going into the transmission (pin), independent of the coupler and the mid rod (which goes to the front ball joint) then your shift coupler is not holding the rear rod (the one going into the transmission) properly.

RonnyÅ

It is the pin going in to the gearbox I can rotate, not without moving the gear lever.
Anyway, the number on the gearbox was G28/03. 119 0098

Found out the gearbox numbers 119 refers to 1979 and 0098 is the serial (and actually the same last numbers as in the cars VIN.
