I have a 2015 Hyundai Santa Fe sport automatic transmission. It won’t shift right until I switch the sifter to manual and it seams to shift fine. When in automatic it won’t shift passed 3rd at it takes a long time to get to 3rd. HELP Please

 

Got my problem figured out. The second catalytic converter was plugged so I couldn’t get any exhaust out of the back of the tailpipe and it fixed my problem. The transmission shifts with no problem.

 

Please get back to us here because what you have determined is the result not the cause.

There us a reason this happened and if you do not correct it , it will repeat and continue.
