I know I will stick out out like a sore thumb as a noob but want to at least save a little face with some solid advice. Thank u all in advance.
It sounds like the 2-3 shift servo is weak, or not building enough pressure for a firm up-shift. It's also possible that the friction material in the clutches may be worn or glazed over.
Boosting the line pressure, either by PCM programming or installing a Trans-Go shift kit, may temporarily improve shift firmness in a worn transmission.
Common upgrades will require a unit rebuild, with added clutches and larger servos. Check RPM Transmissions, a Forum vendor, for their available rebuilds in various stage level upgrades.
