Try checking these two things to save your transmission.
Poor line pressure rise due to leaking boost valve, clogged EPC filter screen, failing EPC solenoid, or worst case: leaky seals throughout. Transgo HD2-C kit fixes first two without removing trans. Seal restorer may fix last problem, but probably R&R. Also try a transmission flush with BG brand products (Firestone stocks it).

Check TPS for smooth electrical response. If the response is jumpy or erratic at all, replace TPS.
The code 83 i not sure what that is, i don't have it in my lap top. hummm
