  1. tried the search option...and came out empty...I have a T-5 tranny that is a Tremec T-5 since it is a 92...I ran the number's on the tranny to verify that it was...anyways...the problem is that for some reason I cannot downshift to 2nd gear...and if the tranny FINALLY allows me to...its very hard...Now when I start out from 1st, and than go to 2nd and so's noise, goes in with I don't think that's the syncro...or is it? but if I'm in 3rd or 4th and am in the proper RPM to still downshift to 2nd I can't...WHY? Also same deal with 5 gear...for example when I go from 5th gear to neutral...and than when I try to put it back into 5th again it will not go in...SO I have to put it in forth but not release the clutch and than quickly go to 5th again...WHY? Is it that maybe my clutch cable is stretched out and is not disengaging from clutch...? Am I low on fluid? what should I look for? it's not the shifter...I alreay swaped that out...this is very puzzeling to me... :shrug: thanks guys...
  2. Two words - Bad Syncros.

    I don't know how you feel about the DYI thing when it comes to gears, some people don't like the idea of working on transmissions. If the DYI transmission fix idea isn't something that you would rather leave to someone else, here are some resources:

    See to download a FREE service manual for T5 or Tremec 3550
    You will need the Adobe Acrobat viewer which is also a free download –

    See or for parts

    A T5 rebuild kit with syncros, bearings and other small parts costs about $160. It does not include any gears or shafts. also has a video on how to rebuild your T5 or Tremec. It costs less than $20, and is worth every penny of it.

    I did a Tremec 3550 rebuild, and it wasn't that difficult. The video was an immense help, and I would recommend viewing it. At $20, it will give you an opportunity to look and decide for yourself if you think that it is something you want to try to do.

    You will also need a magnetic base and dial indicator to measure the endplay ($20-$40).

    The tricky part is that you will need some shims to adjust the endplay in the two shafts: the new bearings will change the clearance. There is no way of telling what it will be until you get to the point that it is time to measure and check the clearances. Halon has the individual shims if you can wait for them. If you can't afford the wait, the auto parts store can sell you some shim stock and you can make your own, or have a machine shop make them for you. The shim stock comes in brass (easy to cut) and steel, in varying thicknesses. That's where the dial indicator & base come in - there is no way to get the clearance right without it.
