I had to park the Mustang. I think my clutch is coming apart, which is unexpected since it has never been abused. Over a two week period, the symptoms got progressively worse.
Suddenly, I could not downshift into second in order to navigate a 90 degree right turn. I was able to get it in once I bumped the lever a few times. At this point I thought my 2nd gear syncro was toast. I dismissed the clutch as the cause because all other gearbox functions were unaffected. I could even get into reverse without a crunch, which eliminated the clutch as the cause in my mind.
At the end of the two week period, suddenly all the gears were tough to get in-out of and reverse crunched like crazy.
I put the car on the lift and confirmed my hydraulic clutch mechanism was moving the fork far enough for complete disengagement. This leaves dropping the trans as my next step, but time is in short supply until the second week in December at the soonest.
It is a disappointment to have this failure, but I've got something clunking in the front suspension when I reverse and turn out of a parking spot, so I've got to troubleshoot that too. I've put a few thousand miles on the car, so I should take the time to give it a once over and check for loose stuff that should not be loose. I need to get the horn working, along with a few other odds and ends.
