/8 Transmission not engaging

Hi everyone!

I'm still having trouble with my clutch even after bleeding the slave cylinder several times. Short of taking the clutch assembly down, is there something I need to check first?

Where are you located in the world?

Are you saying you can start the engine with the trans in neutral, but then cannot shift into any gear without grinding noises?

If you put the trans in first gear and push in clutch can you start the car? - If not, then the clutch discs could have bonded to the plate. this can happen if they get wet and sit awhile.

solution to that is raise back of car safely on good stands. start car in 3rd gear push in clutch pedal and stab the break pedal a few time to break clutch free.

Thanks, rumb!

I'm in Manila, the Philippines.

The car starts with the engine in neutral but I can't shift into any gear.

I haven't tried starting the car with the shifter in first gear but the car was not used for over a month before this happened. I will try starting it in third and stab the brake pedal several times as you suggested. Just curious if this will work considering that the clutch fluid reservoir is separate from the brake reservoir.

the high humidity there could cause the clutch discs to bind to the plate.

try the starting in first gear with clutch pedal pushed in and let us know what happens.

Should do the trick ,its the Manila humidity that has bonded the plate and flywheel with rust.normally frees up with a couple of attempts to shock the clutch😁

My 1975 parts car had a clutch pedal that was as hard as a rock at mid pedal. The clutch and pressure plate had rusted together. It sounded like a very similar situation, but I could specifically feel in the pedal where it should disengage. I was able to line up the gears and shift into various ones.

I'm not sure that starting the car in 3rd gear would be the answer. I would think that 1st would provide more torque to break the rust, and in the event you don't get the car shut off in time (because the pedal is still stuck), at least you won't be going as fast. The bucking action of 1st gear starting might actually be good to break the rust.

In my case, after I removed the trans, I was able to strike the pressure plate with a hammer and it came right off.

Be careful starting it in gear!!

If you look, my method involved safely putting the rear of car in the air first.
