Toyota Probox transmission & gearbox repair
This page covers transmission & gearbox repair on the Toyota Probox specifically: what we inspect on this model, what owners usually notice first, and how the repair is carried out.
Diagnosis, repair, overhaul and installation of automatic and manual transmissions, including clutch and mounting work.
What we find on the Probox
On the Probox we assess fluid condition at operating temperature and log shift behaviour on the road before recommending any internal work, since fluid degradation and a failed solenoid produce the same symptoms as a worn unit.
Small hatchbacks are used almost entirely in traffic, so clutch, cooling, engine mountings and front suspension bushes are the components that actually wear out.
Symptoms owners report
- Delayed engagement when selecting drive
- Revs flaring between shifts
- Harsh or hunting gear changes
- Whining that changes with road speed
- Burnt-smelling transmission fluid
What the job involves
- Road test recording shift points, slip and flare between gears.
- Fluid condition and level check at operating temperature.
- Scan of transmission control data where fitted.
- Repair, overhaul or replacement with mountings and seals renewed.
Components typically involved
- Clutch assembly
- Torque converter
- Valve body and solenoids
- Gearbox mountings
- Seals and fluid
When to have it looked at
Service automatic transmission fluid on schedule; heavy traffic and hill work shorten the safe interval.
What to expect
Road test and fluid assessment first. Overhaul work is quoted with a completion date before the unit is removed.

Frequently asked
Is a slipping gearbox always an overhaul?
No. Low or degraded fluid, a failed solenoid or a worn mounting produce the same symptom and cost far less to fix.
Is this job different on a Probox?
On the Probox we assess fluid condition at operating temperature and log shift behaviour on the road before recommending any internal work, since fluid degradation and a failed solenoid produce the same symptoms as a worn unit.
