I know this is pretty vague sounding, but there is like this burning smell after I stop and park my blazer.. almost smells like burning rubber, may even be oil.. my oil coolant lines leak.. which I am getting fixed this week.. would that have anything to do with it?

 

May be tranny fluid leaking onto your exhaust pipe. Check the pipe that goes from the header under the engine .

 

check the vavle cover gaskets for an oil leak too. they can leak onto the exhaust.

 

What color is the tranny fluid? There was a fluid leaking like under the engine right near my passenger front tire.. it appears to be clear and it doesn't have a smell.. I was told it was my ac just sweating, like a fridge per say.

 

The tranny fluid is red. and yeah thats just the AC sweating. its normal.
