# Codebook: random 50 complaints naming P0700 (one primary category)

V — Valve body, solenoid or hydraulic control: a valve body, solenoid, mechatronic unit or torque converter clutch is diagnosed or replaced, OR (if no diagnosis is stated) the companion codes are solenoid/pressure-control/clutch codes (e.g. P0747, P2714, P2732, P0776, P0796, P0741, P0777, P0964-P0966, P2706, P2764, P2817).
T — Internal failure or replacement: the transmission is diagnosed as failed, or a rebuild/replacement is recommended or quoted, or internal mechanical damage is named (wave plate, clutches, torque converter).
S — Sensor, switch or wiring: a transmission sensor, range switch or harness is diagnosed, OR companion codes are sensor/circuit codes (P0711, P0712, P0717, P0722, P0705, P0851).
N — Network or power: communication codes (U0100, U0073, U1000...) or a module power/fuse problem is the stated or evident cause.
E — The P0700 rides along with a non-transmission failure (engine stall/shutdown, overheating, engine faults) that the owner describes as the main event.
U — Other or undiagnosed: no companion code or diagnosis, or the complaint is about another system.

Rules: a stated diagnosis or repair overrides the code family. If a replacement is recommended but a specific valve body/solenoid is named as the cause, code V.
