Transmission Killer

[leeputmanjr]

My recently ressurected '74 "Beast" Spider has an issue unlike any I've heard of before.

Driving along fine (at a hair-on-fire-pace), had to come to a very abrupt stop, jammed the brakes, and afterwards, I couln't put it in gear. I might have also jammed the clutch too hard, not sure. Turned the car off, put it in first, and started it to at least move out of the intersection. Brief, strong smell of burning rubber. Initially, I thought I'd lost my clutch cable.

It moved about 100 yards when it began acting like the clutch was slipping, the more the engine reved, the less she moved.

I was able to put the car in gear at this point, but with zero "motive power".

Upon inspection, guibo is fine, clutch cable is fine, clutch arm travel seems fine, pedal seems normal, maybe a tad light, but that 'could' be my imagination.

What the heck did I do? Is it possible to jam the throw-out bearing into the fingers of the pressure plate? If so - permanent damage? How to fix? What else could it be?

First off, get your furnace repaired!!!

Did you downshift or over-rev the engine when you made that sudden stop? A high reverse load on the clutch will buckle the drive straps on the clutch cover plate.

If you crawl under the car, remove the inspection/dust rubber cover on the clutch throwout arm you will be able to see the clutch cover, the finger springs and the throwout bearing.

sounds like you need one of my new high-performance clutch sets. The pressure plate will have an added strap to prevent buckling as Matt described along with other performance mods

okay... I'll bite: WHAT (or WHO) the HECK is a "Guibo?"

Sorry to hijack Lee, but Mark do tell about the clutch. Is this from the SEMA show? I'm looking for an uprated clutch for an engine I'm building. Maybe start a new thread in the performance section. Pictures, Prices??

Maytag, Guibo is the rubber "doughnut" that links the transmission output shaft to the driveshaft. (6 bolts) If you don't know what it is, or when it was last replaced, get a new one $20 is cheap insurance against a larger lumpier trans tunnel.

Matt
I'm supposed to get the first clutch on Friday. I'll definitely post pics and info as soon as it arrives.

Will the clutch be more of a racing style "limited slip" clutch, or will it be suitable for everyday driving?

Thanks,
Josh

[So Cal Mark]

it will be a street performance clutch, suitable for everyday driving, designed for cars with increased hp. It's a low-cost alternative to a racing clutch. Racing clutches will be available also in the near future.

Here's a picture of Guibo, working on my car right before FFO 2008:

Ted,

you were sorely missed at pick-a-part. or was that sourly missed? i can never tell...

Mr. Putman wisely chose to grab the tranny from the parts car as he packed his toys for the day. I think he now has a great winter project ahead of him.

[So Cal Mark]

we can do an aluminum flywheel, but the mfg is discouraging me from offering it for anything other than race purposes.

Sorry Mike, could not make it, was traveling over to see my parents in good old Rockford. Did you get that windshield changed out?

Ted, you need to get with Jim Scurria on the clutch setup he's using if you're looking for a true race clutch. I promise you'll love the extra torque!
