Ah, well, it is under warranty, and luckily for me, i had an oil change with them a couple weeks ago. They are supposed to do a check of all belts/hoses/fluids on an oil change service, and they did document that they did do that.
And when i went back, they said i needed to do this service, and so i decided to let them do it, I paid about 100$ cdn for them to do this, and i have it documented that they did this as well. They didnt do it for free as it is supposed to be regular maintenance.
Tried some highway driving yesterday, it was slipping and shifting poorly at high speeds.
The problem still occurs, so i will bring it back to them to have a look at it. The technician drove it and they did not find a problem so i will drive it and show them the problem...
