I'm wondering the same I think mine are going bad. From what I've heard it can be a pretty expensive repair mainly labor. High hundreds from what I've heard. Hopefully someone with more know leg can chime in

Id have to show you after I get out of school. Plus I'm not sure how I'm going to show it. I've just been shifting and it's been annoying because it grinds, making it tough to put it in gear unless it's something else(pressure plate,etc..)

check your clutch cable, quadrant, etc. could be that its still rubbing the flywheel, and turning a bit. Im not sure what bad synchros feel like, but sometimes grinding is caused by slack in the cable.

what i want to know, is what happens when the synchros are absolutely shot? do you just cram it into gear? drive it like a semi? go nuts power shifting all day?

but if you gotta fix one synchro, id just invest in a transmission rebuild. or swap it for a rebuilt transmission. if a synchro is out, then who knows what gears or bearings will go.
what was that transmission place called? i think aamco. they specialize in transmissions. may cost a pretty penny but i would call them first.

Make sure that your clutch is adjusted properly first of all. Just take the dust cover off on the bottom of the tranny to expose the clutch fork. If the cable is too loose you might not get the disengagement that you need to smoothly shift gears. I personally wish there was a way to convert these transmissions to a dog-box. Dog boxes are ****in sick

As in, put a dog ring on instead of a syncro ring and have the gear machined to accept the dog ring. Maybe you could have some gears synchro and some gears dog box lol.

it's hard to diagnose synchros unless you tried refilling the tranny fluid and adjusting clutch. Even at that point it could be anything from a bent shift fork, worn out shift fork pad, broken gear, and then maybe a worn out synchro. Really you need somebody to drive your car to tell if it is synchros. And to see what's really is going on it needs to be taken apart.

I had bad synchros once before a couple times and continued racing, eventually the pin that held the shift forks in place feel out and I had no 3rd and 4th gear. I got a link for you where you can buy synchros. And you may want to do what I did take the tranny out yourself, and give it to the person who will rebuild it. I got a couple of guys in my contacts that will do a tr-3650 rebuild for 350$ idk if one of them are any good though. I know one is because he showed me how 3 times.

Well I'm not sure if it is the synchronizer. Dustin told me I need to fix it. But you could be right on that. And rebuild my tranny for 350$?

Try draining it and filling the tranny up with synchro mesh first if it doesn't fix the problem. Just don't shift hard, shift slowly that's what caused my gears to go out before.

Not sure where you guys have landed on this but I just bought my 02 that we think the 3rd gear Synchro is going out on it. I called like 10 shops in my area to get quotes. So far from what I've read above everyone is on the right track. grinding can be a lot of things. It could just be some slack in your clutch cable and cost you nothing but some of your own time to tighten it up. It also could be any number of things involving the clutch, fly wheel, and tranny all together. I got estimates ranging from $800 if its just the synchro all the way up to $2300 if its worst case scenario.

IMO if it starts to get anywhere near $1500, I'm going to be looking for a nice new transmission.

Bottom line is that until you break open the tranny and find out exactly what it is, its hard to say just how much it will cost.

yea^ personally I think mine is the clutch cable. If mine is the synchronizer I wouldn't mind as I've heard multiple times the car can run fine with bad synchros

One thing to keep in mind is that with bad synchro, you will likely damage other parts of your transmission over time. It may only cost you a few hundred now but if you wait, you may end up having to do a complete tranny rebuild. Yes you can run with bad synchros as long as you can perfect double clutching and not power shifting but thats only a temporary fix to a permanent problem.
