February 11, 201114 yr Author comment_345455 Any luck? Not yet. There's SNOW on the ground outside! Yeeeech! No, it will have to wait for warmer weather.FAIW, I've recently acquired a Miata and am also active on a forum for that car. This same problem occurs in Miatas (also 2nd gear), and the solution seems to be Redline fluid. So I might try changing out for Redline first, as well as bleeding/flushing the clutch. If that doesn't work, then I'll probably dive into a rebuild.

February 11, 201114 yr comment_345482 FastWoman,Many years ago, I pulled the 5-spd of my 1st '77 and had it repaired by an expert (broken synchro). I used a motorcycle lift to replace the tranny. Getting it out wasn't that bad but having it lay on top of me was a bit claustrophobic. I had two helpers but we had difficulty manipulating it, just decided to go in and act like a human dolly (hey, I was younger and dumber!). You are welcome to use the lift when you're ready, if you choose to go the self-reliance route.

February 11, 201114 yr comment_345485 I have an adapter that goes on my floor jack that allows you to tilt, turn, angle, a transmission. It makes it so much easier that I've actually done a couple of them by myself Link to comment https://www.classiczcars.com/forums/topic/37897-synchromesh-worn-out/?&page=3#findComment-345485 Share on other sites More sharing options...

February 11, 201114 yr comment_345501 You mean when it's runnig? Like match the revs and just do clutchless shifts? I used to do that when I was young and crazy......

February 11, 201114 yr comment_345506 Like Steve said-match RPMs and don't use the clutch.If you can shift the trans without using the clutch and no "sounds" are heard from the box,your synchros are healthy and your problem lies elsewhere.

February 11, 201114 yr Author comment_345507 Oh, I didn't see the prior posts! Willoughby, thanks! I might take you up on it. OTOH, I have a neighbor just down the street who restores a LOT of motorcycles. I bet he has one too. Steve, that sounds like a pretty useful approach. I might be able to cobble something together from wood for just the one job. I'm thinking of something on the end of a plank. One end of the plank sits on the ground, the transmission is strapped to the other end, with shims to tilt the trannie as needed, and the transmission end is jacked in the air by an arm extending off the end. But again, I'm waiting for warmer weather and will be trying Redline and a clutch bleed/flush first.

February 11, 201114 yr comment_345509 If you do it right, it won't hurt your trans. If you do it like I did in my younger days...well you were already considering 'diving into a rebuild', right?
