T18 Transmission jumps out of 4th gear

I'm no transmission man but I have rebuilt a couple. I'd say syncros are bad, but I'd also say the pilot bushing is too. A worn pilot bushing will let the input shaft wobble and if the syncros are border line worn let it pop out. Like I said, I've just worked on a couple. I'm sure someone here can help or give more insight than me.
I know since I rebuilt my T176 it hasn't popped out of 3rd and it used to pretty often. The syncro's were really bad and it had a T-150 pilot bushing in it which was way too big for the 4speed and didn't give any shaft support. The T-18 shouldn't be too big a chore to put syncros in, just watch how it comes appart and lay it out piece by piece. Invest in some GOOD snap ring and retaining ring plyers. I got my rebuild kit from a place in Knoxville called, What Ever It Takes. They were cheaper by far than any place I found online or off. The kit was quality stuff, good bearings and seals. Good luck with it

Got Torque Stud? (aka: transmission stabilizer stud) It also could be the clutch alignment, bad motor mounts, and a host of other things but I would start with the stud and mounts. I had a T150 pop out of third after a professional rebuild but didn’t have a torque stud.
