Check Auto gearbox

[Gabe]

Clio Mk4 RS Cup (200) - 2014, 105k Miles

2 days ago I received check auto gearbox and Car was stuck in 2,4,6 and reverse. The message was there for 10 minutes. I turned off the car and switch it back up and message was gone. I went to mechanic and he ran Diagnostics and it said transmission control module - Clutch motor 1 signal (Implausible signal) i Figured since its Clutch 1 that's why the car was stuck in 2,4,6 and reverse. Any idea why this might happened or how to fix this. There was also a lot of other short circuits to earth errors.

First port of call on these is to replace the battery if its over a few years old, with a decent AGM item.

Issues you have listed could be a multitude of things. Id get the codes cleared and the shift drum and clutch actuation reset and see what comes back

I had shift issues and tried lots of things, checked and replaced loads, ended up being the TCU though

Thanks I'll try replacing the battery and will see if message pops up after that

I checked the battery now its 12.5V when car is turned off and 13.8 when engine is running so I suppose the battery is not faulty?

It has active charging and drops off when not needed. Voltage doesnt necessarily prove the battery is good either. Still worth getting a proper check on it.

As above change it out for a good quality AGM
