Hi,
I just bought a 1987 K5 blazer with 4 speed overdrive transmission and 5.7l engine. I noticed today that it looks like when i stop it leaks a few drops of transmission Fluid. I have started the troubleshooting (just wiped off the area to check tomorrow morning), but was wondering if any one else might have some ideas.

This is what i have found out so far:
Not more than a couple drops (creates a mark on the pavement about 2" diameter, but not pooling)
Consistent in that every time i drive it and stop it drips
It is from the front of the engine compartment, below the radiator (it has a new radiator) from some silver tubing that looks like it could be a tranny cooler.

So far not a big deal, i was going to get a transmission service (drain and replace gaskets) done this weekend along with a LOF, but i figured i would put up a post and get some other thoughts.

I can post pics if any one would like to see them

Thanks

 

Sounds like you may have either a loose line into the stock cooler in the radiator or a cracked line. The lines are pretty easy to replace on a fullsize.

 

Thanks, that is what i figured. I am going to spend the weekend getting to know the underneath of it. don't even need jacks!
