I have a 2000 elantra with transmission issues. Ive read one post similar to my issue with slight differences. My sister was driving the car when she felt like the car was hitting an ice patch, she said the car went to first gear right now! its since been brought to my house and put on a computer. codes are p1709 kick down servo, p0734 a/t 4th gear ratio, p0732 2nd gear ratio and p0722 output spd sensor ckt . the car will go into first and very intermittently go into 2nd and 3rd, reverse is totally dead! anyone have any ideas? any help will be appreciated.
