Technical Diagnostic codes P0710 and P1742 on 500 dualogic.. please help

[welshlad46]

As per headline, my wifes car has been randomly going into N usually when approaching a junction or a roundabout in 4th or 5th gear. This has nearly caused vehicles to go into the back of her and she is now scared to use the car (dont blame her).

I took it to work today and got the garage to plug there diagnostics machine in with the following codes

P0710 - Temperature (from CAN)
- Intermittent

P1742 - Gear selection sensor
- Intermittent

im trying to chase up the garage I purchased the car from as I had issues when I got it where on cold mornings it wouldn't go into gear (reverse if I recall) so they changed the oil at there garage and still it played up so they informed me that it had to go to a Fiat dealership for a new gearbox. Now I purchased the car in early 2019 but it had 74k on it then with the "new gearbox" and my wife now only has 81k on it so surely it would not of gone already?

Any help is most appreciated

There's a parallel post in the dualogic issues thread, and that's where this question properly belongs.
