i have a 88 chevy silverado with no forward or reverse gears.
88 chevy silverado, 350 and hydromatic tranny...prolly a 400??? anyway, i went over railroad tracks yesterday and lost forward and reverse. I changed filter and fluid today thinking maybe filter fell down and still when you put it in d,r,1,or 2, it does nothing. Engine doesnt even sound like it has a load. You can rev it up and will sometimes feel like it is engaging but not enough to drive. I was able to limp home in what felt like 2nd gear.
