Toyota Tarago Gearbox & Transmission Problems

A lack of drive in an automatic gearbox can be down to a number of things. Most commonly, it’s internal wear inside the transmission or torque converter that is not transferring drive from one component to the next. This can be caused by broken or loose vanes in the torque converter, a failed transmission pump, a faulty valve body, worn clutches and bands or a mechanical failure of the gearsets. And more.

Any of these things will require a transmission specialist to assess and repair, but before you do that, check the level of the fluid in the transmission. Low transmission fluid can easily cause this very problem and a top up may restore drive to the vehicle. Then, of course, your job is to find the source of the leak, because the transmission is a sealed system and should not require top-ups outside of regular servicing. But it might just get you back on the road in meantime.
