C4 won't park - parking pawl issue
C4 won't park - parking pawl issue
1964 Comet, C4 trans.
So a while back we were getting a ratcheting noise from the trans. We pulled over on the side of the road, slowly moved back and forth. The noise sounded like it was coming from right under the trans. Having no choice, we drove slowly on, the noise increased and then suddenly went away and all seemed fine. Later we notice that the car still rolls in park. I'm now thinking the noise was the parking pawl and that it probably bent or broke off (which is why the noise went away).
Question: Can I get to it to replace it without taking the trans OUT of the car? Shop manual and internet are kind of vague on this. Looks like if I remove the pan and the valve body I can get to it from below?
Anybody ever mess with this (I know, Roy, one more reason to ditch the automatic

I'm interested in the answers to come too .I have a c4 in a truck that you just cant trust.
Re: C4 won't park - parking pawl issue
YOU do not have to pull the tranny,drop the pan,,the pawl broke and the little ball lost cotact...back in the middle to late 70's ,ford C4's were known to jump out of park and actualy ran over people,my 77 bronco does it and 1 time my issurance had to pay for the side of a brand new truck at a gas station,it came out and rolled back into it,thank the good lord there was no one walking behind it....leaving for the races,,,,wish us luck pop

Re: C4 won't park - parking pawl issue
Groover, take a look at this pic. Its the parking pawl (laying flat, below the long straight spring to the left of the gear). It engages that "gear" when in park.

Dont trust your shift linkage just yet. Remove the linkage rod at the trans and verify that it is really in park by moving it with your hand. Click it into park manually and then see if the car rolls. If not, its in the linkage...perhaps adjustment or maybe worn somewhere.
It it does roll the parking pawl set up needs to be checked...everything Ive read says the trans needs to be disassembled to replace it. But Ive never done it. Im fixin to tear a C4 down to rebuild. But thatll be awhile.
Good luck!

Good luck at the races, Pops, Thanks Joe.
Pops, are you saying you've DONE this from below the pan, or are you saying you think it can be done through the pan.
Looking at Joe's exploded view pictures, and from what I've seen online, it looks like you could adjust the mechanism from below, but if the spring is actually broken, it looks like it is outside the pan area??

Re: C4 won't park - parking pawl issue
Looks like its on the tail housing side of the trans. I wonder if you could remove the tail housing to get to the spring??

Re: C4 won't park - parking pawl issue
Thanks Pops, I won't be doing this for a couple of weeks at least. Not in the mood right now. Developed a starting problem yesterday (as in it flat won't start) so that's taking irritatingly higher priority.
How'd you do yesterday at the track?

Re: C4 won't park - parking pawl issue
Can the parking pawl, shaft, spring and gear be replaced via the rear tail housing (or must the main case be exploded as well)?
Thanks,
