Default Issue with 4th gear - 06-09-2018, 10:27 AM

This might be the wrong place and if so I'm sorry.

I'm trying to get down to the bottom of an issue I have sometimes when I put the car in 4th (manual transmission) about 1 in every 50 shifts the car goes into 4th the car will just rev and nothing else, no resistance or anything. It's like it's in neutral. When I does this I have to force it back into neutral as it gets jammed where 4th is meant to be. I never have any issues any other time and all shifts are silky smooth other then when it jams, tia

hmm ... sounds mechanical, maybe synchros are messed up, or slightly bent shift fork?

if it was hydraulic or slave cyl, would expect first gear at a stop would be grinding or difficult before 4th.

Sounds like syncros. This happens to my second gear, like nothing is there.
