Depending on the severity of the leak the oil level dropping in the engine
in a manual there will be engine oil leaking from the bottom of the bell housing, (there is usually a hole drilled there for specifically this reason)
In an auto (depending on variety of trnasmission and torque converter fitted) there will be contamination of the converter oil or the transmission oil, or again engine oil leaking from the bottom of the bell/torque converter housinigAnswerI had this problem with a 1985 Ford Bronco. I bought the truck with the problem which just got worse and worse. you can tell because you will see an slight oil leak under the vehicle toward the back of the engine. On my Bronco it was in the back of the engine but before the transmission.From all highway driving, under the truck I had oil on the bottom of the transmission, on the muffler, on the front of the rear axle, the rear stabilizer bar bushings were inflamed with the saturation of oil which caused them to split and last but not least, the oil would cover the rear tailgate and window of the truck. This was caused by the draft from the air as the truck was driven on the highway.I had to wash the back quite often, nevertheless, constantly add oil. It got so bad I was adding the oil from my family's oil changes just to get to work and back home.I still sold it because of the plow on the front end.
rear main seal
You will have to replace the rear main seal. This will require that the transmission be removed.
Water can not leak from the rear main seal, only oil. Most likely there is a leaking freeze plug near the rear main seal dripping water onto it.
Rear main seal.
Overheating can damage any seal.
They don't make anything Liquid in a can that will FIX a rear main seal leak. Time to replace the seal and be done with it.
Depends on where the leak is falling from it could be the rear main seal leak, transmission back part connected to the transfer case, or a front main seal leak, the transmission part connected to the engine block also a possiblity is the shifter gear box if you have a standard, which also be in the front near the front main seal.
No a rear main seal is the rear seal on the crank shaft of the engine. That portion of the engine is wear the crank shaft connects to the clutch and pressure plate (manual transmission) or where it connects to the torque convertor automatic transmission.
There are some oil additives you can get, that might stop the leak. But if the leak has developed, the only way to fix it is to replace the seal.
Well the rear main seal is at the rear of the engine and would leak engine oil if it was leaking,but if the rear main seal is the leak? it usually requires the removal of the transmisson. But if you know that it is transmission fluid then I would check the transmission cooler lines, transmission cooler, and transmission pan gasket for leaks.
Yes, this is when it would leak.
Rear engine crankshaft main seal or front transmission seal. More than likely rear main.
A leak happens
Check your tail pipe you may be burning it in that case you need a valve job not a rear main seal, if it was coming from your rear main there would be oil along bottom of motor and could mean your PVC valve was clogged

Sure. Get a second opinion or get someone who is good with cars to check it for you.

It depends on the seriousness of the leak. Basically, if you car is not in top condition/repair you should not drive it.
If it's on the back, possible rear main seal leak. Is there oil leaking onto the driveway? Another possiblity is valve cover leak. Its best to check your valve cover closely for leaks and fix them (if present) first prior to replacing the rear main seal.
