sycro gear or clutch goin?
 

i think my syncro gear is going. cant down shift in secon unless im goin bout 10 mph starts grindin like crazy. same thing when going to 5th gear have to shift slowly so it doesnt grind. does this sound like the syncro or the clutch.

if it is the syncro would it be cheaper to get another tranny or rebuild it. dont have any tools so would be a mechanic doing the work. not working with a whole lot of money too. thanx for the help

Yeah, that sounds like a synchro gear. The second gear synchro is notorious for going out for some reason. As for the cheapest way, ask around. The previous owner of mine found one form a lower milage car that he swapped in - I think it was about 800 or so.

It's a syncro problem.

Some people recommend replacing the transmission fluid with MT90 and rear differential with 75W90 NS.

double clutch to downshift

Thats kinda strange that it would only be 2nd and 5th. You dont have problems with any other gears?

that never works for me. I have to rev match for my shifts to shift gears. double clutching doesn't do shit.

i cant just slam it into any other gears or it will grind too but 2nd and 5th are a big problem

so do i need to get som1 to fix the gear or should i change the tranny

ooh my tranny has the same problem, I found a way around it, Just fake your tranny out push it into first dont let it go in but you can hear the tranny hiss at you if your going too fast for first gear, after you hear that hiss you can put it into second. I've been doing it for almost a year now. Also Redline MT-90 gear lube will help alot if not solve it.

Huh? Double clutching is just fancy rev matching that doesn't involve wearing the synchros at all. As a matter of fact, double clutching will work perfectly on a transmission with NO synchros at all, which is how the early manual transmissions were built.

if you want the problem solved then rebuild the tranny. but for the cost of rebuilding you could do a used t2 tranny swap and enjoy it much more.

wat do you mean enjoy it more? is it less expensive to put a used tranny on

When downshifting on a double clutch, your brain/foot is the syncro... you clutch it out, rev it up, then clutch it back in... double clutching without reving it up between clutching on a downshift will not fix your grinding problem. Symantics I know : ) But that's what syncros do to my knowledge... they match engine and tranny speeds... downshifting, you have to increase your engine RPMs between clutching.

BUT, get it fixed and this is all a mute point. :D

the cost to rebuild your current tranny would be about the same to buy and install a used t2 tranny. t2 trannies have lower gear ratios (more accel.) and can withstand larger amounts of torque. I read today in a post a figure of 250ft/lbs on a t2 tranny, 150ft/lbs in a n/a. the t2 tranny is far superior.

Unless im misunderstanding "clutch it out" and "clutch it in", what youre talking about is just rev matching. Double clutching is putting it into neutral, and then blipping the throttle before downshifting.

I understand the point you make, but you are talking about used parts. When you rebuild somthing, you know the condition of it.

I don't know about Orlando, but here in Southern California, it costs $450 to rebuild an FC transmission. That's from a bench rebuilder and it includes bearings, synchros, gaskets, and seals.

Sounds like we're talking about the same thing to me... example... downshift from 4th to 3rd... you "clutch it out" of 4th to N, you "rev it up" with the throttle a bit while in N, then you "clutch it in" to 3rd gear at the top of your rev. I'm a truck driver (a semi)... I rev match/double clutch a couple thousand times a day. And teach others to do the same. No syncros in the truck....

just make sure to release the clutch while the stick is in neutral and rev it up, then clutch again and finish your shift. once your good at it, it doesn't take much longer that a normal shift.

I like my synchros. If I'm downshifting to anything that will end me up over 2000 RPM, I double clutch. I have to really work to *not* do it, at this point. It's smoother, easier on the tranny, just as quick (or faster, depending on how your synchros are), and most importantly, FUN.

Plus, pulling off a perfectly smooth 5th->2nd downshift with absolutely no vehicle jolting is a nice way to impress other stickshift drivers who haven't figured out the tricks yet. And while it doesn't impress the ladies that much, the fact that you're smooth will impress them, especially if they've ever ridden with not-so-great stickshift drivers before. I've had more than one woman comment on my ability to shift smoothly - I suppose it's not as common as I had assumed.
