unbolt it and carefully tie it UP (prop shaft), and with a hard rear bias.
Id use bunji cords.

Most of these do not have a transmission fluid drain plug if yours is an automatic. My 1995 did not have one and the entire pan had to be removed. Mine was a 4x4 so I had to disconnect the four bolts that holds the front drive shaft up just so I had enough room for the pan to come down. While I was in there, I removed the old transmission filter and there is a magnet in the bottom of the pan that catches metal shavings. Go ahead and clean all that out while your in there. Get you a transmission filter kit and it includes the new pan gasket. You can do this job with fairly basic tools and patience. Just take one corner of the pan loose at a time to allow most of the old transmission fluid to drain. My tracker didnt want to shift into second gear until it warmed up. I ran some Sea Foam brand transmission cleaner through it and then changed fluid and filter after driving a couple of days. Totally fixed my problem.

it may be the sensor if it has one or it may be the unit it self

Go under the vehicle and check the four wheel drive linkage.

Take a look at the transmission oil pan. If you see two drain plugs than you have the trans without the dipstick. One of the plugs is actually the drain plug. The other one is the fill plug. More often than not When you go to remove the fill plug the nut on the inside of the pan breaks free from the pan casing the plug to just turn. The norm is to have to replace the pan anytime a service or fill is needed. If you have the trans with a dipstick than you can add the fluid through the dipstick tub with a small funnel.
