The problem with shift kits most times are not the kit. The installer thinks if some is good, MORE is better.
In the directions on modifing the valve body it may have had some steel balls to be added or removed, or a passage drilled to go from stage 1 to stage 2 and stage 3............
Common error is to jump a couple stages and it may mean pulling the valve body apart again.
And NO we do not need the 5:1 ratio kick down lever on the street.

thanx for input, I went through the whole valvebody and directions were followed to a tee and everything was good. Might try bringing the pressure down a tad reducing the throttle pressure cured my tf2 blues. i'd never use another one.

remember turning the pressure up you turn the screw counter clockwise, to lower pressure screw it in

back off the throttle pressure adjustment until the shifts are normalized. I believe he was referring to the kick down rod adjustment. IE: shortening the length normally results in an earlier WOT upshift  that is what i'm referring to.

I'm not a trans specialist but I have rebuilt a few of each .
Be careful of backing off to much on your throttle pressure linkage just to get civilized shifts at low rpm why because when you pour the coal to it you might be compromising pressure to your high gear clutch pak ! specially with a 904 with its puny clutch surface area.
In my honest opinion your better off with a properly adjusted stock valve body rather then backing of a VB with a shift kit. JIm
the tf 2 kits come with a heavy throttle pressure spring and I think that's the culprit. when using a stock type spring there really isn't a need to back the throttle pressure off some, even though the service manuals show the pressure backed off. when the throttle pressure is set like what we'd do with a stock spring the tf2 kit won't let the trans upshift, even with a stock governor. I wouldn't use a tf2 again for any reason.

I like TF-2 kits. More is not better. I’d recommend remove the pan and turn down the pressure at the main spring with the Allen screw. Now you can have your throttle pressure where it should be. This way you will not have the possibility of smoking the hi gear clutch pack. the pressure spring in the kit I used is backed off all the way per the instructions.

I too have used a few TF-1's as a quick fix for a car. It is a basic kit. Yes you can over step it.
I've done more TF-2 kits and they are more race ready than the TF-1 requiring drilling passages and such.
For a basic lazy shift improvement and not chirping the tires going from 1st to 2nd I recommend a TF-1 set on Street. Yes turn the pump pressure up to the lowest setting of Street.
