1) Coolant temp, TPS, and/or MAFS
2)Pilot bearing, input shaft bearing, ring gear, or a host of other bearings. Used tranny is cheap, and rebuilds can be messed up easy
3)99 percent chance it's the subframe bushings. The entire rear subframe sits on a few bushings. The front ones tend to go leaving a lot of movement and a metal to metal clunk

On the radiator there is a sensor that tells the Electronic control unit (ECU) when to turn the fan on and off? Or when to adjust? You have to locate. Trottle Position Sensor (TPS) Located on the trottle air intake near the Trottle cables i.e. one for the gas peddle and one for the choke. A little square black b plastic ox 2"x1.5"x 0.5" Replace but don't turn the new unit axil on installing, will damage. Last the Main Air Flow Sensor (MAFS) this is after the air cleaner filter follow the air line 3" dia. until you find the fixed box with black plastic top. Terrible too replace, good luck:?

Regarding the thump in rear end. Check your Body mounts. There is a rubber bushing or shim. mine was rotted out, replaced it with a chunk of hard rubber about 1/2 the size of a hockey puck. The problem went away and it took about 1/2 hour to do.
