Did you put ENGINE oil leak in the transmission? That's probably why the transmission locked up. If you put it in the engine, it had nothing to do with your transmission locking up. In either case, your vehicle needs to be diagnosed by a reputable, qualified transmission shop.

check your rear main seal. Also try changing your trans fluid, trans filter, and your transmission pan seal. I recommend you put lucas transmission oil in it and a quart of the Lucas Stop Slip and leak sealer

The Dodge Dealer is saying the crank seal and cam seal are leaking when they went to change the oil, are these transmission seals or engine seals? do I need to place them or is there a product that will...

Crank seal could either be at the front or rear of the engine (there are two) Cam seal is at the front of the cylinder head. If the leaks are minor, a good product that may help is lucas conditioner and sealer. Larger leaks require an actual seal replacement. No sealer will work immediately. The reason most leak is because over time the seal hardens from heat. It takes a while to soften it up again.
If the leak is from the rear main seal, the transmission needs to be removed to get to it but neither seal is part of the transmission.

Chances are slim that Lucas would solve your problem. Lucas only works in certain very select situations. You need to know where it is leaking from first. They can leak from front seal, rear seal, speedo o ring, and or pan. If it is a minor leak it may work.

Leaking seal cost to fix?

which engine? if it's a 4.0L the seal is in the rear main bearing cap...I have seen people do a replacement without removing crankshaft but have never seen one done this way that worked. If leak is small, try some lucas sealer...It softens the seal and swells it a bit. Also use oil for high mile engines afterwards...that too contains a conditioner.
(cheper to try this than removing engine)
Good luck!!! If engine is not 4.0 check back with me and I'll tell you what I think. I didn't mention cost because engine removal is a lot of $$$

Transmission leaks 5 lts. every 6 mounths.not on ground or rad of motor

It's not leaking, it's burning it. Try adding an oil stabilizer, such as Lucas. Common among high mileage vehicles.
