I have recently had a nightmare taking my car to Mazda.

First of all my AT Light came on and car went in to limp mode so I had it towed to the dealership, they said I needed a new transmission so I had a second hand one put in and picked it up did exactly the same thing took it back they said it was an output shaft speed sensor wasnt that so I took it back and this time it was apparently the TCM Module wasnt that and they didnt believe me so I got a second opinion and was clearly right. so I took it back and paid more to have a reconditioned transmission put in and this seems to have failed on the freeway last week going in to limp mode and idle was all over the place and jerking to a stop..
It is now back at the dealership and they have said they dont know what it is so they have sent it back to the transmission place..
Please tell me someone else has had this issue and if so any idea what it could be?

This is really a long story cut short.

 

Very uncommon. Feel free to ask them to submit a tech case to Mazda HQ. If they refuse, hit up Mazda Australia customer care direct.
