So have a new problem with the 81 928 5 speed.

When I first start the car I can easily put the car in gear and off I go. I can shift into all gears (although the 1 to 2 syncro will grind if you you shift at high rpms). Anyway it seams once the car warms up, and I come to a stop, it's very, very difficult to shift out of the current gear and into another gear while the car is at rest. So going from like 1st to neutral to sit out a light, i have to litterally almost jam the car out of gear. Goes back in fine and when the car is moving shifting is fine. Any ideas? Maybe a fluid level or easy adjustment....fingers crossed???

 

it sounds like the flex line is getting soft might be time to replace it

 

I have a 79 us model. A while back my clutch pedal travel would shorten when the car got warm. Decided to bled the system(the one fluild I hadn't changed) and all hell broke loose. Seems that the systems are old and when you do this things break(seals etc) and you end up with more issues.

Seems to be that is you have a issue, redo the whole system and get it behind you as it is a biggie. Clutch master, slave and rebuild your Master brake that is home to the fluild for both syatems, brake and clutch.

Parts aren't that bad price wise but the work is difficult. At least for me. If you don't do it yourself bring it to someone who knows what they are doing. I made that mistake. Mine is in good hands now with Blown 87, Greg and will be back on the road in a week or two. Hope I don't need a brake booster!

My car should be fairly sorted out at that point. Trannies w/ bad syncro's can be driven for a long time when you learn how to shift them. Though a 85/86 tranny will probably be my next addition instead of something that will give me more power!

 

flex line = flex plate? Is this a DIY and can anyone provide any more info.

First thing first is I will check the fluid levels. Only thing is where do I check the clutch fluid levels? Sorry such a noob question.

 

No. Flex line is a flexible line, like the one on your brake calipers, that goes from the car body, to the engine. Can't have a hard pipe there, as it would crack, and fail over time.

EDIT: And it is ofc a part of the line from clutch master, to clutch slave.

...and a pic:

 

I can fix this DIY I think. Where on the car is this located? Is there a way to stop the flow of fluid so I don't get any air in the system once I replace this?

 

the flex line cant "buldge" to get that kind of performance problem. if its bad, its bad and probably will burst or will leak, but it doesnt effect the clutch operation.
you could have air in the system . try a simple bleed first. curious part is that you cant get it out of gear, but can get it in gear. sounds like air because sometimes, with air, the first initial push of the clutch will operate it fine, and then it fades with time (holding the clutch in). thats why you can push the clutch in and get it in gear, but when in gear at a stop light, and then you cant get it out of gear easily.
why do you have it in gear at a stop light? should pop it into neutral before stopping, always.

Late post on this, but I had the exact same problem.

Changed out the crumbled clutch release bushing and it now shifts perfectly.

 

i have the same model and just had a similiar problem,before you get into anything drastic i would top the fluid level to the max its on the brake master then adjust almost all of the freeplay out of you clutch peddle theres a 13 mm locknut to do this its simple and takes seconds.just leave around 1/4 " freeplay in the peddle.

 

I bought my 79 with a blown flex line, PO did not want to mess with it. This is my first 928 and as such I would consider the clutch hydraulics a DIY with the help of this site and the link below. A lot of great information on Sharkskin's site BTW.

I had exactly the same symptoms (intermittently) when I first got my 82 5 speed, and found I had multiple issues causing it ..... a worn clutch release arm ball cup, worn gear linkage ball cup, worn rear coupler bushes, badly adjusted intermediate plate, and a tired slave cylinder.

None of the individual problems were bad enough to be the sole cause, but put all or some of them together and it was a total PITA to shift .. sometimes. Sometimes it would shift fine and others it would grate and jam, especially on a long run or when it got hot. I figured that sometimes all those things were coincidentally at their extreme of malfunction/out of adjustment, which then made it difficult/impossible to get in or out of gear.

Check everything in the chain of connections in the gear linkages, check the clutch adjustment and of course check the hydraulics as already discussed.

Don't assume it's a particular problem, or just one problem.
