1999 1500 sub trans
I have a 1999 1500 4x4 suburban. When first put in gear it hits hard, like its in low range. Then you
accelerate and it goes but then starts to slip, revs to 4-5 k then let off and it grabs second hard! This
continues through all the gears. I'm thinking pump?? but I am not sure maybe sol. any help??? thanks
