Wondering if changing tranny temp sensor is easy or does it require dropping pan? Or, is there a way to disconnect so my overdrive will continue working. This is a 99 with over 200k and the light comes on almost immediately after starting. It's full of fluid and even after driving a few miles fluid is only warm to the touch on dipstick. Only gave $800 for pickup so not wanting to spend much on it. Any advice is appreciated.

 

sensor is in the governor sensor or solenoid
