The A5HF1 solenoid pack fails from heat in V6 Santa Fe and Sorento applications. This is the primary repair on this platform.
Symptoms: DTC codes across P0750 range, limp mode, harsh shifts, MIL on
TCC failure in V6 applications from high torque and neglected fluid. Sorento V6 towing accelerates TCC wear.
Symptoms: Highway shudder, DTC P0740, fuel economy drop
AWD Santa Fe and Sorento applications accelerate clutch pack wear from combined AWD and V6 torque.
Symptoms: Slip under acceleration, DTC P0732–P0737, RPM flare in multiple gears
A5HF1 rebuild replaces solenoid pack, all clutch packs (upgraded frictions for V6), torque converter, and all seals. SP-IV ATF used.
SP-IV ATF every 30,000 miles. Sorento owners who tow should add an auxiliary cooler and reduce intervals to 25,000 miles. AWD models should also service the transfer case separately.
Hyundai Santa Fe 2001–2012, Kia Sorento 3.5L 2003–2010, and various other Hyundai/Kia V6 crossover applications.
Solenoid pack failure causing limp mode — very common on V6 Santa Fe and Sorento.
A full rebuild ranges $1,600–$2,100 at Chicago Transmission.
