    get a helms manual ... and good luck. the b series trannys are a difficult thing to master. if you can get it for a good price, i'd say have someone do it for you.
    i am also planning on the LS 5th gear for my ITR tranny

    If it is a cable tranny, they are not too difficult if you are mechanically inclined and you have a helms. I have never been in a hydro tranny.

    Where are you? It's a worthwhile mod if you spend a lot of time on the highway. If not I wouldn't recomend it. With a B16 you won't have much acceleration in 5th. If you can't afford to be down for a while get someone tha knows what they are doing to do it.

    I just put all new synchros and a couple of gears in my hydro GSR tranny, and it was pretty easy for the most part.
    Here are some of the things you will need:

    good manual
    large bench to lay everything out on
    hydraulic press
    bearing puller to get some of the gears/bearings off of the mainshaft and countershaft
    torque wrench
    feeler guage to measure the synchro to shift fork clearance

    A couple of things to keep in mind: While you have the case off of the tranny, look closely at the dog teeth on the gears. My synchros were to the point that the teeth on the gears were worn down and the gear had to be replaced. Also, make sure that you don't put anything on upside down - some of the differences are very small between upside down and right side up. One more thing, if you have to change any of the bearings in the tranny, make sure to check the clearance according to the manual and shim the case accordingly. Good luck.
    BTW, if you need help, i have an OEM manual that I might be able to photocopy and mail to you. Let me know.

    Where did you get new synchros for the GSR tranny?

    basically get someone who knows what they are doing to do it for you, unless your interested in being a tranny master.

    heh

    I got the gsr gear (only third was bad) from my honda dealer. I also used 99-00 Civic Si synchros. All totaled, it was around $650 I think. I know that a new tranny is not to much more expensive than this, but who knows the condition that one is in.
