1987 928s4 stuck in 3rd gear

[stephen picking]

my 928s4 now seems to be stuck in 3rd gear haven't a clue what could be the cause or the solution. i am new to Porsche after owning a total of 5 Mercedes over the years.never had one problem with any of my mercs but have had a lot of problems with the 928, the main problem being there is only Porsche dealership in northern Ireland and they are not very helpful (unless your wanting to buy a 997) plus real car enthusiasts like the smell of petrol not coffee when they go to look around cars(know what i mean).
so can anyone out there help me out with some advise.

Steve,
Your description is not complete, however; if the car is a five speed it is possible the shifter ball socket poped out. The other possibility is the rear shifter coupling.

And if you have an automatic then its a Mercedes problem.

First thing to check on an auto is fluid level, replacing if old.

Shifter on a 5 spd connects to two rods on the bottom, one going forward with a plastic cup over a round ball (cup pops off ball).

thanks for the advise. as far as i know my car has a 4 speed automatic gearbox. i can select reverse/neutral and park but only what seems to be 3rd going forward.i changed the gearbox oil and filter and adjusted the bowden cable but am at a loss at what could be the problem.

i replaced the gearbox oil and filter and adjusted the bowden cable. according to my handbook the car has a 4 speed automatic gearbox . i can select reverse/neutral and park but the car seems to be stuck in 3rd gear going forward.
any ideas?

All gears are in 3rd? Just to clarify, when you put in "1" or "2" etc it stays in 3rd?

as you say . when i select 1st 2nd or 3rd. it just seems to stay the same as drive.
