Workshop says gearbox overhaul — when is it really needed?
2026-05-06 · 4 min read
Gearbox overhaul is one of the biggest repair approvals a car owner can face. The right question is not “is the workshop cheating me?” The right question is “what proves overhaul is needed?”
Owner takeaway
Do not approve a major repair from a vague symptom alone. Ask what test confirmed the failed part, then compare itemised quotes.
When overhaul may be real
Severe slipping, metal debris, repeated fault codes, failed pressure tests or internal damage can justify overhaul.
When to slow down
Low-speed jerks, delayed engagement or occasional hesitation may need diagnosis before overhaul.
What to ask
Ask for fault codes, fluid condition, adaptation readings and whether a smaller repair was ruled out.
How to compare quotes
Compare diagnosis, warranty, parts scope and labour — not just final price.
