What could have pulled the cable out of the proper location? Did you check the trans mount to make sure it didn't break, moving the tranny to cause problem the with the linkage.
The bolt shaft pointing down through the TP lever was really close to the shift lever anyway, so I'm thinking either the park lock rattle when I put it in park with the trans still turning or just a fluke that it did it the next day after it ran fine the day before.
I wanted to put the TP cable bolt shaft facing up through the TP lever just because of that possibility, but the pivot end was too big to fit between the levers.
I just bent the TP lever up about 1/8 inch so everything clears by that much now.
I have a super heavy spool type PST poly trans mount so it really can't tear or move and cables for both the shifter and the TP so I don't think they should be affected much when the trans bounced.
