I checked the transmission and it gave me this code P1771 shifting position, any info about that?

Question

Transmission in my Santa fe is fine but I get a funny vibration (or kicks) after driving long distances then slowing down to almost zero. Or after driving for a long time in traffic jam.

Answer 1

P1771 4WD control , ECM thermal protection

The vehicle that you have is 2WD and at times uses a 4WD for driving condition such as cornering , or accelerating, One of the component that can set this code is worn tire, check the tire, this includes the pressure, if the tire are very worn you can expect this code to set.
