  1. Sounds like the syncro is shot. Time for a tranny rebuild or replacement. There's no good cure for that.

     

    You can try a quart of Rislone in place of one quart of gear oil on a fresh fill of the tranny (takes about 3.7 quarts). But it sounds like it's probably pretty shot.

    http://www.rislone.ca/34471.htm is that the correct Rislone stuff? I have no idea. Thanks!

     

    the best way to stop this from happining in the futher is dont drive with your hand resting on the shifter it keeps presher on th the syincro hud and bras brake and wares the groves of:banghead::dead:

     

    I never do this. Not sure if previous owned did, however.

  2. If it actually was in gear but did not grind until you let the clutch up - it's not what's making the grinding sound. Or do you mean you thought it was in gear, but then found out it was only partially engaged and grinded?

     

    Are you sure you don't have shift linkage problems? There's a plastic bushing that can get worn and make shifts from 4th to 5th problematic.

     

     

    Clutches usually go first. Then after a lot of grinding gears - the spurs that allow them to "lock" get worn off, and then they pop out.

     

    I'm not sure why I bothered mentioning all this - since there is no external fix if your problem is inside the trans.

     

    Losing a 4th-5th clutch is unsusal though. Usually 1st and 2nd are the ones that take a beating and wear out. That fact alone would make me want to make sure that the shift linkage was working OK. Does it still feel as tight as it always did?

     

     

    From what I could tell I thought it was engaged, but I could very well have been wrong.

     

    Not really sure if It is clutch linkage issues, im going to take a look tomorrow with a buddy and see what else we can come up with.

     

    Unfortunately I just bought it. It was uninsured so I had to drive it on dead end roads and never got into 5th when I tested it. It was driven by an old man who presumably never got into 5 much either which confuses me.

     

    I'll probably end up trying the Redline as suggested by gbhrps and see if it gets any better. If not I guess ill be avoiding 5th unless its a linkage issue.

     

    Thank you very much for your help!

     

     

     

     

     

     

     

     

     

     

     

     

    mwynne,

     

    First off, there is something worn on the inside of the tranny that is eventually going to get worse and require repairs.

     

    That said, you may be able to forestall the repairs for quite some time. I have a 1954 MG TF roadster that has a four speed that would grind going into 3rd, or gearing down from 4th into 3rd. It was doing this from the first day I owned it over 20 years ago. About 10 years ago I found a thread on another forum (1990 - 1996 Nissan 300ZX's) that a member had a similar problem and simply changed his tranny fluid to RedLine MT90 and his grinding problems disappeared.

     

    I replaced the fluid in my MG to the RedLine MT90 (Manual Transmission 90 weight) and immediatedly the tranny was much quieter and, if I didn't rush the shifts up or down, the grinding was eliminated. That was 10 years ago, and granted, the car is just a toy and doesn't get a lot of miles put on it, but it may make a significant difference in your case. It certainly won't be expensive to give it a try. Good Luck!

     

     

    Thank you very much! I will give this a try and see what happens.

  3. Hey,

     

    My Legacy grinds just about every time I change from 4th to 5th just before it is properly into 5. It is the only gear that grinds. I have tried shifting slowly, pushing over really far, the middle, and as far left as possible without putting it into third, and about 95% of the time it grinds with varying degrees. Just for something else I tried double clutch upshifting and it would go into 5 seemingly with no issues but when i started to release the clutch it would start to grind, and I pulled it out. I was told by a friend to post on here to see if you guys had heard of this before and have any solutions. If you have any questions feel free to ask. Would really like to get this figured out as quickly as possible.

     

    Cheers!
