95 camaro 3.4L is leaking water behind the motor in between the transmission & the oil pan. what can it be?

You need to determine if it is your oil pan, oil sender switch, oil filter, etc. dripping oil onto your exhaust causing the smoke, or if it is coming out of the exhaust itself. If it is dripping onto the exhaust, deal with sealing the affected area. (new oil pan gasket, sender switch, etc.) If coming out of the exhaust, indicated worn piston rings or valve seals.

could leak water pump that what you did.

Need to inspect closer and make sure the exact place the oil is coming from....Most common places that leak are around valve pan cover which is located on top of motor and in alot of cases can run down back of motor onto transmission or bottom or motor. Another place is the oil pan which is located on bottom of motor. If leaking from either of these you would need to replace the gaskets. Two other places that are common for leaks is the front and rear seals in the motor. Try cleaning bottom half of motor off with a degreaser in the area where you see yhe oil dripping and then you should be able to see exactly where it is coming from. If the leak is underneath where the transmission is bolted to the motor this would indicate that the rear seal is bad. To replace it you will have to take transmission out to do this and if this is the case and your truck has a automatic transmission have that seal replaced also. Yhe reason for this is if you have to take transmission out then you may as well change transmission seal also but remember only if the transmission is a automatic.....hope this helps and good luck....Please rate this post...

Sounds like the rear main oil seal on your motor is leaking. In order for it to be replaced, the transmission has to be removed. Not an easy task for the backyard mechanic.

It's usually the rear main oil seal that's located immediately behind the oil pan on an engine. They do eventually leak and need replacing. Have it checked out.

the flat pan behind the motor that has sortof a triangle shape is the transmission pan

there are frost plugs on the engine block behind the bell housing, bu first make sure that the plugs on the heads are not leaking, removal of the trans, is no fun but may be the only solution

Using a chain block or a portable engine hoist , remove motor mounts & raise engine enough to remove oil pan. You may have to remove some rad hoses etc. to give you the necessary clearance. Remove pan carefully & clean & install new gaskets & seals if necessary. Place wooden blocks at motor mounts for safety sake. Good luck!

it could be leaking somewere else , get your cooling system pressure tested at a shop

If I rember correctly, there are two freeze plugs in the back of the block, behind the flywheel. They generally dont go bad often because they are pretty much protected. As that angelo guy said, more likely a hose or rear of intake gasket, but you have to look, from here I can't see it!!!
