Transmission Repair on a Mitsubishi 3000 GT
Transmission work splits cleanly into three tiers: fluid and filter, electronic and hydraulic control, and mechanical rebuild. They differ by an order of magnitude in cost, and which one you need is determined by a scan, a pressure test and what comes out with the fluid — not by the symptom, which is often identical across all three.. On a Mitsubishi 3000 GT (1990-2001) the parts and the labour time are specific to the model — it is a coupe, which changes both, so we confirm the year before quoting rather than after.
