Why does my 2013 Ford Mondeo wagon only shift gears properly in manual mode?

Asked by Peter

My 2013 Mondeo LX wagon has a transmission problem. The engine surges up to 5000rpm and speed remains the same, but it's okay in manual mode.

This is a bit of a weird one because the only difference between using manual mode and fully-automatic mode is that you tell the gearbox what gear to be in in the former, and the gearbox decides for itself in the latter. Beyond that, the exact same process is going on inside the transmission. Which means, I’d expect the same problems to be apparent regardless of what mode you were driving in.

Your gearbox is doing what’s known as `slipping’ or `flaring’ and that can be caused by a number of things. Those include low transmission-fluid level, low fluid-pressure caused by a worn pump or accumulators, a damaged torque converter or worn out bands and clutches inside the gearbox. The low fluid level is easy to check and address, but anything else probably points to either a new gearbox of a rebuild of the current one.

The wild card is the difference behaviour between auto and manual mode, so perhaps it’s a problem with the electronic solenoids that control the shifts. It could be that the gearbox is not shifting properly in automatic and will only behave when you prod it via the manual-shift mode. A scan at a workshop might give a few clues in this regard.
