1998 Oldsmobile Regency Cooling fans not running

My olds has developed an overheating problem. I have determined that the radiator cooling fans aren't coming on. Since the larger of the 2 will come on if I wire it directly, I think it must be a fuse or more likely, a relay. I think it is located in the relay center under the hood but not sure which is the correct relay. Not seeing any markings. Can you tell me which is the fan relay?
I also have recently developed a hard shifting condition. It seems to slam into the next gear abruptly causing a big jolt. It seems to be shifting at approximately the right time, just very harsh. I checked the fluid level and it seems like it may be too high. Could it be as simple as draining some fluid out? Unlikely. Please let me know what you can. THX
