Hey guys I just started getting a small leak under the transmission somewhere and under the cats from around that area what can it be? I check my oil but it seems fine and the leak looks like oil dark. Its a very small leak too like a few drops every time I pull in the garage.

i'm just fixing some leaks myself. if you can be more specific as to where its coming from then i'm sure we could help more. in my case it was dripping down the rear of the oil pan and front of transmission, the source was the rear main seal and the upper oil pan gasket. the cause was most likely a biuld up in crankcase pressure due to blocked PCV valves (about $3 a piece) so if you dont know the last time they were replaced or cleaned then you might try the easy cheap way to fix the problem before digging in and droppin the transmission and all that.
