I was wondering has anybody done anything to there 30RH? After, I install the SC...I been having some funny shift patterns...:(

Did you mess up the adjustment on the Throttle Valve cable when you installed the supercharger? Only other thing it could be is that the PCM is confused and is locking up the convertor at the wrong time.

I just get this slugish shift....It only shift funny around 3k...Most of the time its normal...

Then I'd just make sure the TV cable is adjusted properly. If not, the trans probabally just needs a rebuild. Since there is no vac modulator on a 30RH, there's not really anything the supercharger could do to effect the shifting - except for the lockup which is controlled by the computer.

How do I know if it adjusted properly? I didnt even touch it. It just hit 67k and I dont think it need a rebuild...Maybe just a nice shift kit will do the job or maybe its my ECU still confused..:(

If you just installed a supercharger, th TV cable might have been inadvertently loosened. Look st the throttle body. There will be two cables goin to it. One is connected to the gas pedal, the other is connected to the tranny. It has a button that allows you to adjust the tension on the cable. When you look at it you should understand. If you don't, you should not be messing with it. :) Tighten up the cable a notch or two. It should firm up your shifts nicely.

A shift kit isn't going to fix a problem that just cropped up. And I'm not sure how you determine that a trans doesn't need a rebuild when you havn't looked at anything, but start with the cable adjustment.

OK, that's a page from the 94 FSM. You'll need to find the adjustment procedure for your year. You have to be carefull about just messing with the adjustment randomly, it can burn out the clutches if you get it set incorrectly.
-
The big concern is setting too loose. That is how you can burn the transmission up. If it is too tight it will not want to shift until a higher rpm/throttle angle.

I went and check the cable...no slack in it...So I think its good..;D

That would be a wrong assumption.

How? I even tooked the connector off the TB and checked to make sure the TB is not pulling on it...

That's the problem. You are assuming that zero pull means anything, which is not the case for the TV cable on any AW4 or 9xx series transmission that I've ever worked on. You need to get the factory adjustment procedure and follow it.
If you read the procedure for the previous years that I posted, you will see that the adjustment has to do with correctly setting the cable jacket length at full throttle, it has nothing to do with the closed throttle position.

Great! InFo...:D Well, I just ordered a TF-2 Reprogamming Kit from Transgo. I will be dropping it at a tranny shop and let them check that cable and install it...:D

let me know if the trans shifts any better after they put ur shift kit in if u dont mind. i was thinking about doin it as well. thanks
