Greetings,
My 1995 Mustang GT 5.0 T5 pops out of first gear when letting the clutch out. I have changed the syncros after consulting many sources, but it still pops out 90% of the time (shifts better now FWIW). The shift fork did not "seem" to be bent, but it's the only thing I can think of that it might be. Sometimes it will stay in first even under a full throttle launch.
I'm a little mystified and hope someone here can offer advice before I yank it out again.
