my car last had its clutch done in 2003 when I had a precat death short block replaced under warranty, the clutch still grabs nicely today, but I ran into some pecuillar behavior today after taking it out of storage for the year.

I drove it about 30 miles, the trans was grinding a bit swapping gears and the shifter was harder to actuate, after the first 15, I did a more aggressive launch and I felt something in the engagement that was unusual, but the trans shifted butter smooth and everything felt a lot better.

later that day, i took it for another drive, uneventful until i got back into my car, clutch in, selector in reverse, the car started to drive backwards even with the clutch fully in.. I shifted to neutral, released and re applied the clutch pedal, back in to reverse.. no movement but the car REAKED of clutch, drove home with no problems but now Im terrified the friction disc is going to explode and leave me stranded with or without car damage.

anyone know what might be happeneing?

car is a 2001 MR2 with my old 2000 MR2 1ZZ and C56 installed in it. urethane engine mounts and brass shift bushings. only mods that would affect drive.

I'm thinking Rust..

Two Places..

Either Rust on the Friction Surfaces, and the Clutch is Not Disengauging because the 'Rust Fir' is Preventing the Disk from letting go of the Cover..

OR

The 'Splines' are rusty, and the Clutch Disk can not Center it's Self between the 'Space' of the Flywheel to Cover, when the Clutch is Released..

My Advice..

To get the 'Rust Fur' off of the Surfaces.. Slip the Clutch a little in a Parking lot.. like a 2Nd gear Start.. for about 3 to 5 Minutes Slipping most of the Time.. If you start smelling Clutch, then you have Rubbed things enough to make the Rust go away.. This happenes to OLD tractors all the Time

If that does not help, then Rust is Likely on the clutch Splines.. it will LIKELY smooth out.. Just learn how to shift without gringing.. and all should come back to normal..


If, the Clutch Disk is comming apart.. then none of these thing will help, and it will Ultimatly fail..

Till it clears up, do not drive too far from home..

always so eloquent in your replies, Cap

I kinda thought that as well. the car does sit 90% of the year, so that makes sense.

I do have AAA platinum, but would hate the hassle of breaking down and or grenading the clutch/part of the trans.

the C56 is on its death throws already, it grinds up and down in every gear when cold even with MT-90 so I just want it and the friction disc to last long enough to find a reasonably cheap C60!

I will start in 2nd gear a whole bunch for a couple of days now, haha.

=Cap Weir;828694 learn how to shift without gringing..

The 5 Speed that I put Into my Spyder, had Blown 2nd and Fourth Synchros.. and it was not long after that 3 was toast also.. bbut the bearings were good, so it stayed in the Car..

It was mentioned in a Thread about " learning to Double Clutch", the best way to learn to shift, is the Have a Tranny with bad Synchros.. as you know when you have screwed up..

Unless I forget what I'm Doing, I do not grind this ( New to Me ) transmission, as I know how to shift.. But it has not always been that way. I learned on a Tranny with Blown Synchros.. Best Teacher..

You might take this Oppertunity to learn how to shift .. Really

From about '82 to '85, my Daily Driver was a 1940 Ton and a Half Military Beast. The Tranny on these things were built without Synchros.. and it's called a 'Crash Box' 4 Speed. If you screw up, your in trouble.. It's now my Work Truck, on a 7 Acre facility.. rairly get out of 2nd gear.. but No one else can drive it.. as they are nervious about the Gears.. thats fine..

When your really good, you can shift without using the clutch.. ( Except from Start )..

Practice..

I rev match up and down shifting, otherwise my transmission would not leave first gear until full operating oil temp. it will shift without a clutch and without grinding like that (lots of times I have had clutch hydraulics die far from home, starter motor in first, then rev match through the gears. painful, but it works. true.

'double clutching' is not what that is, however. misused term perpetuated by hollywood in 2001.
