Ok, so I did my B16 swap almost a year ago and from day 1 the tranny never shifted smoothly. It was very bulky and clunky into gears and when forces, led to grinding fron 1st to 2nd and from 3rd to 4th, but it was clunky into every gear. I figure syncros, so i yanked the tranny (90 teg xsi S1) about a month ago and have it re-syncroed, bearinged and sealled with a USDM 90-91 teg LS kit. It put it back in and no grinds anymore but it is still bulky and ground once into 3rd. So, is it the tranny still (maybe wrong parts used for overhaul), the clutch (clutchmaster stage 3, maybe it is not fully disengauging from the flywheel, thus pissing off the syncros), or the shift linkage (HASport, I chopped it up an rewleded it because i used the Place Racing mounts which places the engine about 3/4" farther forward than the HASport mounts, so i needed to get the shifter in the correct position, but it has always been a little outa wack). So, please let me know cause i dont want to just start buying new clutches, linkage, tranny etc without some input first.

Thanks in advance

i thinks its time to just start replacin ****...doh

 

I'd start with the linkage. it doesn't spound like you have much confidence in it.

 

actually, I made a discovery today. While driving it, I noticed that if you double clutch it, it does right into gear. Therefore the damn imput shaft is not slowing down enough when i press in the clutch, so I beleave it is the clutch not fully sisengauging. And yes, I have spent about 3 hours jacking with the clutch adjustment to see if that was the problem. Since the tranny has no 5th gear (nimrod who overhauled it left out a part) I am pulling the tranny and having that fixed and when i put it back in, i am going to use the stock flywheel with the stock clutch that came with it. It may be worn and tired, but if it shifts smooth, I'll know exactly what the prob is. Man, I hate pullin trannies...or should i say, puttin em back in.

90% of the time, once a gear starts to grind, there has already been tooth damage. Never just replace synchros without the gear as well.

 

so after a little investigation, I believe i have found the cause of the problem. The CM stage 2 disc is beyond fucked up... After setting up a roling dial indicator i tested the disc for perpindicular runout (wobble) and circular concentricy. The results...terrible...21 thousands of perpindicular runout and 91 fricken thousands non-concentricy....meaning it was not round...at all. Anyway, the out-of-roundness is not a huge deal other than cause vibration and whatnot but the perp runout would not let the disk "float" between the flywheel and the pressure plate. It would actually be bouncing off the both of them at an exponential function of rpm....therefore keeping the imput shaft loaded at higher rpm's....looks like old jose is getting a call at clutchmasters....and he said everything leaves there perfect
