1971 Corvette 4th Gear
Looking at a Vette to buy ,When shifting into 4th gear,sometimes it pops out and the shifter is always hitting against console. Suggestion.

Adjusting the swivel on the 3/4 arm on the shifter would be a good start. Is the shifter hitting the console in 3rd or 4th? The shifter mounts to a bracket that attaches to the frame. That bracket has the ability to be moved in/out, back and forth a bit. If the tranny has been out at some point, it’s very possible that the installer didn’t concern himself with adjusting that

Agree with above, also if you check the 71 AIM you will find that there are shim washers as needed between the above mentioned bracket and the frame which you can adjust to tilt the shifter back a bit. Usually without any shims, my experience is the shift hits the front of the console in 1st and 3rd. However I would guess it could be shimmed wrong in all sorts of ways. Agree, I would again check your AIM and adjust the shifter rods as instructed. If it still pops out, I would think it might a problem in the Muncie. Hope this might help. For me, this would not be a show stopper if the price was good and I liked the C3. However, it would be a negotiating item.

Hitting console in 4th gear
Tranny was out for new synchronizers. Then he never played with linkage but remove the shifter to get tranny out. So he possibly didnt mount shifter in exact position. Then I need to loosen base and move it to get 4th gear not to hit console plate. He also never hooked reverse switch up.

do not fix it for him. tell him the synchros were done wrong and trans is shot. take 2500 or so off price. then fix it after it is yours...

Also re-adjust your neutral while you are determining the shim......if the 3-4 gate is too far back, it may not be pushing the ear on the trans back far enough to stay in gear......
Refer to the AIM for the "shoe shucker" tool.....to align neutral.

why? the guy is selling the car with a trans that pops out of gear. is it the prospective buyer's job to climb under the car and put it right and then pay top dollar for his OWN work? if the seller wants to have it set up properly before advertising it, he is free to. there is ALSO a possibility that the trans is bad and it is gonna pop out of gear when set up properly. and seller may know it and be trying to sell it as good knowing it is not. cuz somebody allegedly replaced the synchros. why? to stop it from popping out of gear? or just grinding when shifting? either way, one would THINK if done correctly, it would be adjusted correctly so that it worked correctly. not like the job needs redone. and if synchros didn't fix the problem, it is gears that are bad. or just an incompetent builder...

Do you really need me to explain right from wrong to you ? .

right from wrong. the seller had the synchros replaced in the trans. it pops out of gear. so, somebody did something WRONG! now seller is representing the car as if the trans is RIGHT! wants RIGHT money for it. the only reason Thelal could justify adjusting that shifter ahead of time is if the seller sez he ain't coming down 1 penny. and Thelal considers the time lost as acceptable to know if seller is lying his *** off or not. how many cars for sale have AC that just needs a belt and a can of R134 to blow cold? it has a trans problem. buyer is negotiating from a position of strength. if it was an easy fix seller would have done so!

is it a Muncie shifter or a Hurst shifter? They could be popping out for 2 different reasons each depending on the shifter.. Fourth gear rarely ever goes bad. Usually it is 2nd that will pop out either going in or on deacceleration if its getting worn.

There are people who hide a major problem absolutely on purpose. It is definately buyer beware!
Not everyone, but some do.
I helped my buddy dissasemble an engine with a mild "knock" that was just "repaired" by a used car "shop".
It wasn't "that" bad, but it had just been "repaired".
We found Wrigley's Chewing Gum wrappers under two of the rod bearings.
I kid you not!
A buyer needs to do his due dilegence. Kudos to the OP.

I have done many 4 speed transmissions and the brass syncro is rarely the problem... I t only slows the gear down. It's the dog housed on the syncro clutch and on the hear that grind and hold the gear in place. AMEN.
