Automatic Gearbox Repair
Automatic Gearbox Repair in Southampton
If your automatic gearbox is slipping, juddering, making noises, or stuck in limp mode, you need a specialist — not a guess. At BMS Garage, automatic transmission repair is our core trade. We handle all major brands and gearbox types, and we're known for solving the problems other garages give up on.
What we do
From diagnosis to rebuild
01. Gearbox diagnostics
Road test and computer diagnostics to pinpoint the exact fault.
02. Transmission repairs
Solenoids, valve bodies, sensors, electrics and software.
03. Gearbox rebuilds and replacement
Full mechanical overhaul or quality replacement units.
04. Hybrid gearbox diagnostics
We also service hybrid transmissions, which most general garages won't touch.
Our approach
Diagnosis first, repair second
We never sell you a gearbox rebuild if a solenoid will do. Once we find the fault, we explain what's wrong, what it costs, and what your options are — before any work starts.
Symptoms we fix
Common gearbox problems
- Slipping or harsh gear changes
- Juddering and shaking at speed
