CVT fluid degradation

Attaches to TOYOTA-CVT at gearbox level · Transmission · carried by 2 variants across 2 chassis

Overview

CVT fluid degradation is a occasional fault recorded against TOYOTA-CVT at gearbox level, typically from 100–200k km. It shows up as a gradual change in how the gearbox holds revs, occasional shunting at low speed, and in neglected cases juddering under load. Where it's documented, the repair runs €200–€350 (fluid change at a specialist, costs dated 2026-07), and it can be difficult to check before you buy. 2 variants across 2 chassis in this database inherit it.

What happens

Symptom. A gradual change in how the gearbox holds revs, occasional shunting at low speed, and in neglected cases juddering under load.

Cause. Toyota specifies the fluid as a lifetime fill. Specialists widely disagree, and a change at around 100,000 km is inexpensive insurance against a gearbox that's otherwise proved dependable.

How to check it

Paperwork

There's little to see at a viewing, so ask whether the fluid has ever been changed and budget for it if the answer is no.

The last column is the point. The same repair is an inconvenience on one variant and a reason to scrap the car on another. A failure costing a quarter of the vehicle's value changes the purchase decision regardless of how rare it is.
