My S10 is leaking fluid from the base of the autotrans filler downspout.
1. I cannot find a manual, any help on that?
2. How is the downspout removed?
3. I tried to unscrew with pliers an crushed spout.
Any help on this hopefully easy problem would be appreciated.

thats not a downspout its a vent pipe. if it is leaking from there its either overfilled, coolant in the fluid, the case is porous,or the drain back holes are plugged.
