ATF coming out the filler tube ? that's a new one on me , have you checked the tranny fluid level when it's HOT , truck idling on a *perfectly* flat and level place ? .

Off hand I'd say you need a new Mechanic .

As much as I love old Chevy trucks , this may not be a good choice for a working /towing vehicle as you're not a Mechanic and any 36 year old truck is going to need fairly constant fiddling to make it a reliable daily driver .

I'd love to have found it a few years ago when I needed a I6 powered automatic short bed .
