Default atf in the engine compartment

Hi everyone, i'm new the the K5 blazer, but i'm fairly experienced in engine work.

I purchased an 89 blazer with the 350 and a rebuilt 700r4 transmission. i was driving it the other day in 90 degree weather for about an hour and shortly after i stopped to hook up to a small trailer i was having a real hard time engaging reverse. then i noticed some smoke from the hood and a trail of fluid. turns out a bunch of atf shot through the engine compartment. I've done some reading but would like some opinions. I had to drive it a cpl hundred feet in order to get out of the way of a trucking business asap and it didnt sound too healthy. am i screwed, or should i be ok if i find the cooling hose leak and replace it?

Ok,sorry to sound stupid but i am when it comes to full size blazers. if you look above your transfer case you might see a sensor with some rubber vacuum lines. when the sensor fails the fluid gets sucked into the lines at the engine compartment and sometimes ac. it may have got sucked up and you might had a vacuum leak and it blew all over in the engine compartment.

If you do have that sensor, i cant find a part number,but take it off and bring it with you to the auto store.

k5s dont have any kinda vacuum lines going to the transfercase like a s10 or other newer trucks would. everything is engaged manually or auto hubs up front i guess if that counts. most likely its a transmission cooler line as thats really the only reason trans fluid would be up under the engine as it runs from the trans to the radiator.

i would also think maybe its power steering related as a lot of people put trans fluid in there but if you are having reverse issues, yeah probably a transmission line

for that short of distance, probably not. cars get towed in all the time with blown trans lines or no fluid and a repair and refil of fluid fixed the issue if the truck drove for a while slipping or you let idle for a excessive amount of time then maybe
