Regretfully, I let a buddy borrow my '85 Blazer to go camping. He comes back and something is very wrong with my transmission. I have no third gear or overdrive. It slips really bad when trying to go into third. When it shifts from first to second, it shifts really hard. I checked the fluid level and it is actually too full. Is my transmission toast ? Is it even worth rebuilding ? Any idea of how much a rebuild would cost ? This is such a bummer because everything was going great. Thanks for any help or advice.
