In all honesty you have too much truck for a 60e. I wonder if your 2-3 shift noid went out?
Mine went out on the ext cab i lost 2nd and OD changed the 2-3 noid and its fixed, so you might need to change that or the other one.....they're 25 bucks at the parts store, they both have the same part number, and are located at the back of the valve body.
