There are at least 5 places on the Automatic transmission that can over time, and mileage develope fluid leaks. Front converter seal at the front of the transmission,pan gasket in the center,dipstick tube o ring at the center on one side ,speed sensor o ring,and the tail shaft seal at the rear,of the transmission.
Place a flat piece or huge card board,under the engine and transmission,after driving you will see where the fluid,red in color is dripping. Its easier to spot exactly where the leak is comming if you can look under the car,while it is running, The easiest leak is the pan gasket,the dipstick tube, and the speed sensor,then the rear housing tail shaft bushing and seal.
If the front seal(converter seal) is leaking the transmission will need removed,and the seal,and maybe even the front pump bushing Replaced,it would be a good idea to replace the bushing esp if it has high mileage,80,000 or 100,000 miles of use.Change the fluid and the filter,while repareing the leak or leaks.Is a good idea.

You will have to remove the transmission.that would include removing drive shaft ,possibly exhaust.

That is going to be a front main seal on the transmission if you're sure it's transmission fluid or a rear main seal of the engine if it's engine oil. I put that in here just in case you weren't positive it's transmission fluid. Either way the transmission will have to come out to replace either of those seals.

Check your transmission line's, also look under your car if leaking between engine and transmission more then likely it's going to be your front transmission pump seal, transmission will have to come out to replace front seal.Don't let it run low on transmission fluid or you will have to replace or overhaul your transmission, not cheap.

the front shaft seal is bad on the transmission,pull out the transmission and replace the front seal which is about$8.00 for the seal

A leaking rear main seal will not cause your transmission to leak.

The transmission has its own seal and should not leak because of the engine rear main seal.

Due to the labor involved in replacing the rear main seal on the engine, it is best if you replace the front transmission seal at the same time if possible.

Installation varies on different vehicles but the principles are the same.

That is alot of work. It would **** to have a mechanic paid to do this but unless you are pretty good with a wrench and have a hoist and such then it wouldnt be worth your time. Normally what is required for something like this is supporting the vehicle on jack stands and removing both front tires. Once front tires are removed you would then have to remove the axles which includes the brakes/rotors and what not. Once the axles where removed you would unbolt the transmission and remove it. Now the problem is if the engine is supported by a mount that bolts to the transmission you are going to have to support the motor with a hoist or jack until the transmission is installed. All in all it isnt really alot of work if you know what you are getting yourself into and have all the stuff you are going to need ie jacks/hoists/plenty of tools and a good weekend. Also remember all the small stuff that might need to be unbolted to clear the transmission
