what's causing this?
So here's what's going on in the morning and at night (or just colder outside temps) it feels like I have no first gear. The truck will either sound like im getting on and off the gas and will finally catch or the truck won't move at all unless I floor it. Did I lose 1st gear, or could it be my tourqe converter? The trans was rebuilt about 12,000 miles ago. It doesn't overheat and the fluid looks good so I don't know what's going on with it. Thanks
