Shift Kit

I seem to remember that making the 2-3 shift real stiff was harmfull to something.
(Don't remember what or why though)
Maybe just kinda hard on the direct clutches?

The only issue I've seen, and mind you this mainly applies to 727's but a 904 is so similar it could be the same for them, is if you go too far it may overlap on the 2-3 shift. 904's do have that funky single large spring in the front clutch pack that isn't the greatest so they may be worse.

I think that by the time you get it blocked and everything adjusted you will be fine with it.
Give it some time, because MOST people find out they over did it when they go past the TF2 kit.

I redid one three times for a guy because every time I brought it back to him he said "I'd really like it a little firmer"
When I got done with it, the glove box door would pop open at every 1-2 shift. (he was happy for about a week till the coolness wore of and he had to daily drive it)

LOL... I got a buddy like that. He thinks that if it don't pop open the glove box it isn't good enough.

Oh, and it was a peice of 5/16 fuel line that went through the VB.

5/16 fuel line is so thin wall that doesn't surprise me.
