My 84 928 has problems with the transmission when cold. Its a 5spd. When I start it up after it has sat for a couple of days I have to let it warm up for about 10 minutes before it will let me put it in gear? If I start it and attempt to put it in gear(reverse or first or second etc etc) it will grind? Anyone ever heard of something like this? Thanks in advance!!

Check and/or replace and bleed your brake fluid. Your clutch might not be disengaging properly. My '85 has started to not disengage when I pull into my driveway, and I have to pull it out of gear once I get into the garage~

My '85 shifts hard and grinds after a cold start until it has warmed up. That's one of the reasons I'm planning a major transmission overhaul this year.

Your clutch is not fully releasing. This needs to be fixed, ese you will damage the very expensive transmission.

Two likely causes:
The hydraulic clutch needs bleeding. Take the opportunity to change the brake fluid, which should be done every two years.
Bleed the brakes, starting with the rear. Get good clean fresh fluid from each bleeder.
Bleed the clutch. It is very difficult to get all of the air out. After bleeding it normally, pull the slave cylinder off of the bellhousing - don't disconnect the line! Hold the cylinder with the hose up and push the operating rod firmly to the bottom of the cylinder. This will push any air bubble up and out of the cylinder.
Reattach the slave cylinder and bleed normally again.

If bleeding doesn't help, you may need to adjust the center plate in the clutch. Pull the bottom housing.Have someone push the pedal to the floor. Check the center plate - it should be centered between the flywheel surface and the rear presure plate. If it isn't, it will drag.
To center it, turn the three adjustment pieces located at 120-degree spacing around the plate.
