Car shudders when taking off in 1st

Would appreciate some help

When moving off in 1st the whole car starts to shudder I have to depress and slip the clutch to get a smooth take off. The shudder is even worse if Im stopped on an incline.
Have sometimes a problem to get the car into 1st even when stationary and the same problem with reverse, the gears sometimes grind painfully.

Whats the problem and how do I fix it? The car is a 76 2.0

Thanks

As I said on the World, you have at least a couple of problems.

The grinding is due to the clutch adjustment. Adjust the clutch properly and the grinding should stop. (If it goes out of adjustment again rapidly, you probably have a clutch tube that has broken loose inside the center tunnel.)

The shudder may be due to problems with the clutch/pressure plate/flywheel, or may be due to motor mount or trans mount problems. There could be other possibilities, but those are the first ones that come to mind.

Dave ,

Thanks.

So the first step is to adjust the clutch and see if this helps,
I do not know how to do this. Is there a tech article some place describing the procedure.

Thanks

I had this same problem. The tranny rear mounts were toast. I picked up some nice used 911 mounts for 20 dollars. After replacing car works fine. Also the original mounts looked fine from the outside. Once u pull them out the center just dropped out

Thanks for the advice, I will pull them out and have a look.

What year 911 mounts did you use?

You adjust the clutch by loosening or tightening the nuts on the transmission end of the clutch cable. There is a specified amount of free-play at the pedal end, and that free play is wholly or partly measured by pulling up on the clutch pedal. (There is a spring that pulls the pedal forward and takes up the free play.)

Also check the front engine mounts. If the rubber breaks down and the mount is in two pieces your engine is only being held in place by gravity. Slowly and gently jack up the engine to see if it lifts off the engine bar.

Perhaps. I've seen motor oil in Boxster and Cayman trans from rear main seal or IMS cover leaking. On those it drips down to the bottom of the bell housing and pools with the clutch dust. That will keep it from showing up on your garage floor until the leak gets really bad. I'm not sure if that would be the case on a type 4 or not.
