i have a 95 and have been using tunerpro to program my own chips and shift points. i had my tranny rebuilt early this year with a transgo kit, corvette servo and beefed up internals. i like the firm shifts usually but its to firm at light throttle from 1-2 gear. and to rough also on downshift 3-2. my pressure tables are all stock right now. the tables can be changed based on throttle position and right now they have values from +14 to -25. what is safe to do without damaging the tranny? i just want to soften the shift at light throttle(5-25% throttle) the downshift tables are based on mph in my tables. how much can i change with that? thanks

Did they put the transgo HD2 kit in. if so maybe they put more than one spacer into the accumulator housing.
can you adjust the table so it reads the same pressure at different rpms?

well, the tables on upshift are based on throttle position, and on downshift its based on mph. i dont see where rpm is referenced for these tables. im using tunerpro with a $0d mask. this is obdI. here is a pic of a few of the tables
