Genuine Hyundai 42621 39200 Transmission Assembly Review

The 2012 2.0L engine transmission has an input and output speed sensor. They are located on opposite sides of the transmission under the air filter housing. To access it, remove the case, disconnect the two wire harnesses from the computer, but leave the computer attached to the case. For better access to the front sensor, remove the battery and the battery compartment. After replacing both speed sensors for 3 weeks of driving there were no problems.
