It started about 3weeks ago with a very hard shift from 1st to 2nd and then the last couple days its started to idle really high from 1st to 2nd and from there its shifts normal. It does it 50% of the time now. Within the last 2 months I have had a trans fuild and filter flush done at dealership with correct fuild (MV) and had no problems with shifts points. I have replaced the rears with nitto's nt05 (295/45/18). I have read it could be due to the colder weather and dia change with rear tires. Here's the link to a video I took today.
