Car won't start or drive

[Robert Schles]

Well I just had my first breakdown in my '64. I was cruising along nicely at 65 mph when all of a sudden the engin race with no power to the transmission. I was able to cost to the shoulder with the engine running. I tried going in drive, low and reverse but the car wouldn't move. I turn off the car while waiting for a tow. When I went to start the engin, the starter turned but it wouldn't turn the engine over. Any suggestions on where to start troubleshoot?

I would "guess" the flywheel flex plate has failed. I would pull the flywheel inspection cover and take a look. Did you hear any noise or feel any vibration prior to the breakdown?

[Jason Edge]

David is correct. If you do not see any other obvious issues with the driveshaft, U Jointss, etc, pop the inspection cover.

I didn't hear any noise or feel a vibration but I'll be able to get under the car to inspect it couple of days.
To replace the flex plate, do I need to remove the transmission?

[Robert Schles]

I finally got under the car, removed the inspection cover and sure enough the flex plate is broken.
Jason do you have any used plates available?

[Jason Edge]

I am out of the 64 THM flexplate. I would post on our wanted forum - www.wanted.6364cadillac.com I will also put you down for one on my Wait List.

Sorry to hear it, Bob. I'd check the axle for any obvious breaks or damage, and if okay assume it's trans-related. Flex plate is a likely culprit. Did you leak any fluid, is the trans up to the proper level? You'll remember last year my trans pan leaked and once low on fluid, the trans was not happy at all; I lost reverse and one forward gear. Luckily it was a cheap and easy fix.

Let me know if you want an extra pair of hands while inspecting or yanking the trans. I borrowed an old transmission jack from a neighbor when I thought I'd have to drop mine, and I still have it.
