Can popping out of first gear be caused by a worn out shift lever?

[cdsmith_2002]

My brother is looking at a beater '95 with 150K miles. It sometimes popps out of 1st gear when moving from a dead stop. Is it possible that a worn out shift lever may cause this or is it 100% guaranteed to be an internal transmission problem?

I dont think so, I would lean more towards worn out detents.

The trans has bad sycros

It is an inside the trans problem.

Does he have an aftermarket shifter? Did he check the shift stops?

With that miles, like mine, Its probably synch rings. Is it hard to get it into gear sometimes? My synch rings from 1-2 and 2-3 are basically shot. can still speed shift into them but its not a smooth glide into it(no gears grind thankfully). Mine has NEVER slipped out of gear, reverse does when I can't get it into reverse but thats due to a bad clutch quadrant.

How would syncros cause the slider to move off the gear once it's been engaged?

If the synchros are eaten up they may not have enough material to stay meshed.

Does the shifter handle move/twist while accelerating from a stop? If so that is a bearing problem on one of the gear shafts.

typically its from years of people not putting the car all the way in gear, and it wearing out the closest side of the gear, caused bad meshing and you to loose surface area. Happens alot around here with 5.0s. Guys will be at the track, and it wont go all the way into first, they launch it and it pops out of gear, next thing they know, it constantly keeps popping out of gear unless you hold it in place yourself. Theres an article online about it, basically what i'm saying is its 1st gear gears that are toast.

Thanks for all of the feedback guys. They bolted on a different stock shifter on it today. You all called it. It has some bad guts.

Does the slider engage BOTH the syncro and the gear when fully seated in gear, or does it slide "over" the syncro ring and onto the gear? I'm asking because I'm genuinely curious. Although I have a reasonable understanding of how the T5 works, I'm still learning.

It's been since George Bush Sr. was President since I've been into a manual tranny, but what I remember is that all the actual "gears" are already meshed, with the exception of reverse where a countershaft gear actually engages the reverse gear with 1st in order to change direction of rotation. All the rest of the "engaging" is done with synchronizers. Half the synchro is attached to the gear and half is attached to the shaft. Shifting engages the synchro for the desired gear with the half of the synchro on the shaft required. If I remember correctly the half of the synchro that is on the shaft is the part that moves with the lever.
