Took my s2k to honda today for that nice tranny grind everyone cringes to experience. Honda told me that it would need a new third gear fork and syncrose.
Anyone know of a friggen bullet proof tranny for the s2k that i could bolt up and be worry free for a long time. plz help thanks

 

or if anyone knows of a good fix? I plan on putting red line mt90 in the box but if anyone has any more ideas thanks in advance.

 

sounds about right for the amount of labor involved.

do they grind all the time? If not, why don't you just live with it and learn to rev match (I'm not insinuating you don't know how, just recommending a best-practices). That's the only "fix"

Remember the speed that the input shaft spins inside the tranny. While I guess it could be better, this certainly presents inherent issues. Those syncros must do a LOT of work bleeding off that inertia in a split second. With the speeds the shafts are spinning, I don't think yer gonna find a "bulletproof" tranny. Double clutching, rev-matching, and sequential shifting are the best long term strategies.

 

i have tried rev matching, double clutching it does not matter above 6500 rpms third grinds.

 

Try a Quaife 6 speed sequential gearbox. lookup the web site for Quaife USA. I would go for their race box rather than the Ford based unit as the specialist box is stronger. You will need to get a bellhousing made up. Suggest getting a junk gearbox and cutting and welding a plate to the back of it.

Make sure you get the dog engagement gearbox. These have no syncromesh. You need to make every gear change very quick or it will crunch. Good thing is that you can change gears as quick as you can move your hand. In fact, the quicker you are the happier the box.

Price sounds about right... Very expensive lesson learned!

 

nice thanks for the help, Thats a bad ass tranny but its going to take some Fat cash.
