Default Tranny modulator adjustments

Ok, tomorrow I am gonna go out and experiment with my modulator. First question is -

1. What does turning it clockwise do? Firm up or soften?
2. Is there a preset setting I can use that would be suitable? (I don't want soft obviously, and I don't want hard, slamming shifts.)
3. I know soft shifts hurt a tranny, but do harder shifts than stock hurt anything?

Thanks in advance!

Clockwise = Firmer

The best thing you can do is experiment. Maybe 2 turns at a time, try it out and either turn it up or back it off until you like the feel of the GRAB. Personally overly hard shifts bother me. But I do like a nice TIGHT shift. Mine shifts that way and I'm happy with it. A good solid GRAB.

And Firmer shifts are better for clutches, no change in converter wear, and if you stiffen them too much it prematurely wears on the diff and drive shafts.

It'* a '92.

And your '00 doesn't have one, as it is electronically controlled, just so you know.

After you adjust your modulator, watch out when you shift into reverse when the car is cold It will slam pretty hard..

I always back in to a parking spot if I can to avoid that, but if I can't do that, I will start it up, put the car in drive for a second then go to reverse. works much better and doesn't slam into reverse

Make all your adjustments COLD this time of year. It'll be slightly softer when warm.

Coupled with a shift kit, you can make the shifts BRUTAL. I've played with it to that point. In fact, I had it set so firm that the PCM didn't have time to retard timing at the 2nd gear shift, and the car lurched forward under power into 2nd.

It'll be that way at Wood burn next year.

Yeah, it'* been sitting all night, so it'* nice and cold. I'll start with one turn at a time, just to be safe.

I would just dial it back a hair. No need to put stress on the motor mounts to parallel park

I dont mean to jump in like this but how do you adjust it? Do you take the mount off or just loosen it? Cause i moved mine back in forth before when i was replacing some vac lines, and now my shifts suck i didnt know that it was adjustable.
