Hello Scotty, I have a '10 Hyundai Avante imported from Korea which is basically the same as an Elantra but with a 1.6 L engine and I have a hard shift or bump mostly when shifting up to the 3rd and 4th gears (automatic transmission) with no error codes at all. I checked the A/T fluid and it's bright red and filled to the full mark. What could be the problem and how could it be fixed?
I will , thanks alot Scotty
those have horrid transmissions, but have a pro tranny guy road test it with his scanner hooked up and pray it's bad shift solenoids and not a tranny needing rebuilding
