every shift into 2nd grinds bad but only at about 5-8000 rpm. is that my syncro or clutch or something else......help

 

Try changing the gear oil to redline MT-90.

It will take about a 100 miles for the redline to work its way in, but that should help the bad syncro

 

Are you trying to shift quick? If you slow your shifting does it go away? If so then its probably the synchro, sounds like it is. Mine grinds when I keep it below 4k for breakin but shift fast. Good thing the replacement is on the way.

 

yeah i shift quick but it will do it even when i shift slow when my engine is cold.... and i cant fild red line anywhere but i heard this purple something is realy good as well. and just wondering how much is a 2nd gear syncro....?

 

Royal Purple I believe is what your thinking of. I've heard good things about Neo tranny fluid too on this forum.

 

to replace the syncro is to rebuild the whole tranny esentially... that can cost alot....

i would first try using redline oil in it as that might give you some more life out of it before it becomes worse.

 

well i go to OUC geting my auto teck aprentiship so i have all the tools and time to do it so i would like to get it done before winter and i getpart for dirt chead i can get the whole clutch kit for $100 and syncros for 40 so its not a big deal. but i just want to know if every one agrees that its the syncro.

 

Shifting too fast OR too slow would usually make a bad synchro grind the gears. Just try to learn how to match your gears better on up and downshifts. That, combined with some of the other suggestions (the synthetic gear oil) should clear up a lot of your problems.

 

so you say dont bother with a rebuild?

 

Unless youv rebuilt a manual transmission before I wouldnt suggest doing it. Special tools are required and you cannot disassemble certain gears without these special tools. Its more complicated than you would think...I've done it. If you want to rebuild the tranny have a transmission specialist do it. Of course that wont be cheap. If you want cheap get a used tranny. Either way youll have to remove the tranny which isnt a big deal. Also suggest replacing the pilot bearing while its removed,but your call. Good luck.

 

ok well i have all the special tools you can think of. like i said im at school rite now with a tool room the size of i dont know... BIG. So thats not an isue. and my instructor is tranny specialist. but i dont know if i want to do that. i do have a tranny with 130k on it minr has 170k and tha130is out of an 88 and i have an 87 dont know if its in any beter shape but i will swap it and see i shoul;d take me one or two classes.... good idea?
