Mitsi FTO g/box faults

A friend is having issues with the box in his FTO and getting varying results, he has now had it read and these codes came up:

54 ELC Relay open. What is this?

22 Input speed sensor

23 Output speed sensor

We assume the output is showing a fault due to the input being faulty, is this correct?

41 1st gear not sycromesh.

One place has said replace the input sensor for about £70 + labour and will be fine.

Another place said box is goosed and needs replacement £600 + Labour.

The car is worth maybe £1k so you can see the problem.

Any help/suggestions/ideas

Thanks

FTO tip gear boxes can be a bit twitchy, and getting them repaired can be a bit of a black art- an expensive one at that.

First of all check that the passenger footwell is totally dry. The Gearbox ecu is located directly below the heater matrix. Heater matrix leaks, drips on TCU, shorts it out, you get all sorts of wierd and wonderful gearbox behaviour. The TCU itself is pretty tough and even if leaked on it will normally be okay if it is dried out carefully.

If the footwell is dry, then go for input and output speed sensors. They are about £50 each from Camskill. Depending on the exact model there is a small variation in the price. Takes an hour max to change the pair.

If that doesnt work, then normally it is a 'gearbox cooked' job. Never found anyone decent to recon them for less than £1800. New they are about £5k.

2nd hand can be got for between £300 and 450. If its a 5 spd, expect to pay more (Ie more like £550-600 since they are rare). Swap is about £250.

By the look of your location you are in the North West. Best bet would probably be colin at CMS in birmingham.

Cheers,

Ben.
