How to replace a transmission speed sensor

What year? Auto or manual trans? Input speed output speed or vehicle speed? With a 10mm socket and ratchet, Loosen the intake hose clamp at throttle body, remove 2 air filter housing bolts disconnect the maf sensor and release the wire loom from air filter housing. Remove entire unit from engine, now your trans is exposed. VSS is near the CV shaft area towards the backside of engine. The other 2 are iss -belhousing /torque convertor area Ie engine side of trans and the end case of the trans for oss. IE the fender well- body side of the trans. Both are very similar looking and all use 10mm bolts IIRC. Let me know if you need any more specifics, I prolly have a factory service manual for your car.
