So this 97SS I own, I keep finding little surprises left behind by the previous owner, like the 5" hole under the shifter for his "upgraded hurst shifter" he installed......


Anyways, the shift kit he installed feels great when accelerating fast, maybe alittle too firm cause it constantly leaves rubber going into 2nd.

The problem I have, is it still is really firm when just puddling around, even in a parking lot. It slams into second and is slapping the gears around. Very uncomfortable when not mashing the gas.

Now, I know it has a shift kit and other "upgrades" in the tranny, but I don't know what was done to the software.

Is it possible this can be fixed by looking at the settings in the ecu? Or is this normally caused by a bad shift kit install?

I don't have the means to read it myself with my laptop, can only read OBDI.

Could be both. Zero out the firmness tables and see what happens. You might also have to go into the valve body to fix this.

My first thought is someone put in a Transgo kit and used all three washers in the 1-2 accumulator???

Pro Built Automatics

Yes, that is possible, but you still want to have the firmness tables at zero to start with, then go from there.

Is there any software I can purchase to check that without spending a lot?

I'd like to have an idea of cost to fix before taking it to a performance shop.

Dana, you better give him more specific instructions on which tables to zero so he doesn't run the force motor at minimum settings which is max pressure...

I am not a computer expert, but when talking to Ed Wright or some others who are. The first thing they tell me is to have the customer "zero out" the firmness tables so as to not raise line pressure at part throttle over what was stock, since this makes the part throttle shifts firmer. So when I say "zero it out" is to put it back the way it was. What it is they are doing exactly I do not know. I usually have the customer call Ed or who ever is working on their computer to solve this if they cannot. I hope I am explaining this ok.

That makes sense - return the tables to stock settings.

So I do not currently have software to read OBD II, and do not want to spend a lot. Is there software I can purchase that is on the cheap side?

If you have a lap-top I've had great success and used the software/cable from http://obd-2.com/.
