Q: How to remove and install the Transmission Assembly on a 2011 Kia Sorento?
A: To remove the transmission, first disconnect the cable from the negative terminal of the battery, then drain the fluid from the transmission. Next, remove the entire air filter assembly along with the air duct, followed by the splash shield mounting bolts and shield. Disconnect the wiring harnesses from various sensors including the oxygen sensors, speedometer sensor, Transmission Range sensor, solenoid connector, speed sensor, transfer case shift motor (if equipped), and the oil temperature sensor. Disconnect the transmission fluid cooler hoses and seal their ends to prevent leakage and contamination. For 2009 and earlier 4WD models, remove the front driveshaft and the rear driveshaft. Disconnect the shift control cable and remove the starter. Then, remove the upper transmission mounting bolts and the inspection plate, followed by the torque converter-to-driveplate fasteners, ensuring to rotate the engine for access to all bolts while marking the position of the torque converter on the driveplate. Remove the front section of the exhaust system and place a transmission jack or floor jack with an appropriate saddle under the transmission, using safety chains for stability. Remove the remaining transmission-to-engine bolts, ensuring all connections are disconnected, then remove the crossmember bolts and move the transmission to the rear to disengage it from the engine block dowel pins, making sure the torque converter is detached from the driveplate. Lower the transmission with the jack, using locking pliers on the bellhousing case to prevent the torque converter from falling out, and finally pull the transmission out from beneath the vehicle, setting it aside safely. For installation, reverse the removal steps while ensuring that the drive tangs of the torque converter engage with the recesses in the automatic transmission fluid pump inner gear, confirming engagement by turning the torque converter while pushing it towards the transmission. Align the match marks on the torque converter and driveplate, install all driveplate-to-torque converter nuts before tightening any, and ensure to tighten the fasteners and mounting bolts to the specified torque. Fill the transmission with the correct type and amount of automatic transmission fluid, and adjust the shift cable and Transmission Range sensor upon completion.
