To address the oil in the rad. The oil cooler o'rings must have went bad on the 1st one, 2nd one, on the rebuild must have cut the ring when putting the ends on, you must grease the ends and o'rings when installing the ends back on. To get the oil out of the radiator, you can flush it with a cup of Dawn dish water soap and water, fill it up and run it for 15 -20 minutes then drain and flush with clear water, drain the block also, one drain is on the drivers side rear, the other on pass side behind starter. Refill with FleetGard from TSC, NAPA or IH dealer, it has the SCA in it, get 4 gallons of concentrate and 4 gallons of distilled water.
On the tranny, running HOT, prolly lost the seal on the shaft to the TC, they melt and loose all the fluid, replace with the VITON seal, if you didn't run it to far the tranny should be OK, drop the pan and look for a bunch of clutch facing in the oil or sludge like in the pan, if none or just a little it should be OK. Pic shows what seal I'm saying about, the green seal at the end, the shaft that goes into the TC.
