The only place it could go, is in the Engine Coolant as the trans cooler is built in to the Radiator unless yuo have an external trans cooler in front of the radiator, or where ever you mounted it.
Engine oil that is too thin means its probably time to change it, and check for proper PCV function.

The only other way it can make it into the engine is if the diaphram in the modulator has a hole in it. If it does engine vacuum will suck up tranny fluid into the intake and the engine will burn it. This may also come with odd shifting or white smoke out the exhaust.

Ref. 1991 B2200 truck.
Kyrasis6, hit the nail right on the head. On my 1991 pickup I had to replace a modulator valve, not a big deal, the old one screws out, and think it has a color coded dot on it to match with the new, but not sure, it's been a while. But sometimes if it is just erratic shifting, without tranny fluid loss, it's just the rubber hose on the modulator value has become loose and spongy due to heat, and isn't sealing. So a piece of hose for a couple of dollars will fix it. Had to replace several of the hoses. I carry an extra one in the truck. Take the old hose in, not sure what size it is. 1/4 ID or a mm size smaller. And Yes, if the Diaphragm goes in the Modulator value, your truck will be leaving a heavy trail of white smoke as it sucks the tranny fluid up into the carb and burns it in the engine. A very tell tale sign of a bad modulator valve.

Transmission issues
I have a1991 b2200 with the discontinued trans. I understand all of 80 hp but I lose power going up hill. Just had trans rebuilt. New pump, o/d clutches and reverse, seems to shift great and smooth but doesn't kickdown when I get into the accelerator harder, it has a carb. Any advice?
