Washer does everything but spin, it is leaking oil

My whirlpool washer does everything but spin, it just started this within the last couple of days. Took the case off and notice a small amount of oil on the floor. How do I tell if this is transmission oil, gear case oil, or clutch oil. What do I need to replace? Is this worth repairing?

I am not getting your model number to come up, but if this is a standard direct drive Whirlpool then your problem is your transmission has failed and you can look at the cost of a new one and assess your skills for replacing it. It is not a difficult job, so your call.
