It shifts fine barks tires still, but about 70 mph cruising or at WOT it bucks ands slips i think, its not the fuel pump because i can put it in first and run 5k or so with no stumble, i checked the fluid and its nice pink color still. But just at cruising in O/D I have an Auto 97Z, it will slip , Im calling a gm dealer tomrrow and talking to a mechanic but I want an Idea first, and please no rebuild lol im to damn poor , bur everything below 70 is just fine!

 

Called a shop they said it doesnt sound like it needs rebuilt he wouldnt say what it sounds like but he said for 60 he could scan it and test drive it and see what he thinks, he said parts for a rebuild would be about 500 and 650 for labor that sounds awfully high anyhow but what do you think it could be! Also he said at 75K miles your no where in need of a rebuild and got on to say about the computer controls it and other stuff which i already knew!
