2004 Sonata bucks violently trying to shift into 2nd gear
I have a 2004 automatic 2.7 v6 Hyundai Sonata LX. While sitting in the
driveway, My car idles fine and I have no problem reving the engine up to high
rpms in either park or neutral. I also have no problem shifting to any of the
gears, nor do I have a problem backing out in reverse. Driving slow in first
gear also works fine, but when I accelerate fast enough to shift into 2nd gear,
the car bucks so violently that I feel like I’m going to be thrown through the
windshield. The car never makes it into 2nd gear. I replaced both input and
output speed sensors, as well as the throttle position sensor, but that did not
help whatsoever. Any ideas? Does this sound like a bad transmission
solenoid?
