I have this 2016 Forester 2.5 automatic and this morning when I started it cold the AT temp light, ABS light, and traction control light all came on. It wouldnt shift out of park unless I use the manual override button under the shifter and I had to do the same to get it back into park. It's got 95k miles on her and since I just bought it I dont know if the transmission fluid or filter has ever been changed.. The fluid is full, but its black and smells burnt. It drives and shifts fine once it's in gear. Just wondering if a transmission flush and filter replacement might fix this or if its a more serious issue.
