Re: rear transmission leak
It sounds like you have a tail shaft seal gone in the transmission it's not a difficult fix if you are handy. Remove the drive shaft and remove the tail stock seal(there are install and removal tools but a hammer and a screwdriver will remove it nicely)then replace with new seal (if you don't have the install tool a 5" long piece of 2x4 and a hammer works BE GENTLE!!!!)and reinstall drive shaft..........these seals are available at your local auto parts store and are usually no more tan $10.00 hope this helps!.........good luck!

one of two reasons: 1- the part of the shaft which comes in contact with the lip of the seal has a groove in it 2- there is a brass bushing behind the seal in the tail of the trans which is meant to hold the shaft steady; if it is worn, then the shaft is moving out of range of the seals' ability to remain in contact with it.
Open the hood to access the battery on the driver's side of the truck. Disconnect the battery with a socket wrench.
2Raise the front of the Explorer with a jack. Place the jack stands under the front crossmember and lower the truck on to the jack stands. This will provide plenty of room to work.
Disconnect the electrical connectors at the side of the transmission by hand. Ensure all the connectors are disconnected.
4Unbolt the crossmember directly under the tail shaft with a socket wrench. Unbolt the tailshaft from the crossmember to free it from the bottom of the truck. There will be a series of bolts to unscrew to free the crossmember.
5Unscrew the hanger bolts holding the drive shaft in place with a socket wrench. Pull the drive shaft out of the back of the transmission. Let the drive shaft rest on the ground.
6Unbolt the starter at the front of the engine with a socket wrench. Unbolt the wiring from the starter with the ratchet. There will be two wiring harnesses to remove.
7Unscrew the transmission cooler fluid lines with a line wrench. Ensure both lines are disconnected.
8Place the jack under the tailshaft of the transmission. Strap the back of the transmission to the jack. This will help prevent the transmission from falling to the ground.
9Unscrew the nine bolts holding the transmission to the engine. They will be centered around the back of the transmission's bell housing.
10Raise the transmission up with the jack and pull it away from the engine. Slide the transmission out from under the truck. Some assistance may be required because the transmission is heavy
you will still need add the proper type fluid to proper fill level, get under the truck, clean up transmission so you can visually monitor where the leak is coming from. Chock the wheels, emergency brake set, start and idle vehicle check for leaks. If trans is leaking it will probably be a front seal (oil will drip from small hole in the bottom of bell housing), pan gasket, loose cooling line to radiator, or rear tail shaft leak ( where drive shaft enters the trans.) Don't forget to check the lines for pin holes and the radiator for leaks.
Yes it's a bad seal and most likely the side bearing to the trans axle is bad too. Once the bearing has play, it vibrates and causes the oil to leak though the seal.
Note: if one side went bad the other side is soon to follow since they have the same amount of miles on them. Might as well change both side.
Good luck and hope this helps. Keep an eye on the transmission fluid level, don't want to burn out the transmission.
is it front wheel or rear? if front you have to take down the motor and trans together by unbolting the 4-6 very large bolts and drop the entire front assembly. if rear drive disconnect the drive shaft and unbolt the crossmember get a trans jack or one with wheels that work and unbolt trans from motor. remember to SPIN the torque con when reinstalling.
