Some vehicles can't be towed on their wheels but your vehicle should be fine to tow? Below are the towing instructions for Chevy/GMC trucks.
Chevrolet and GMC Pick-ups can be towed on all four wheels (flat towed) at speeds of less than 35 mph (56 kph), for distances less than 50 miles (80 kph), providing that the axle, driveline and engine/transmission are normally operable. The transmission should be in Neutral, the engine off, the steering unlocked, and the parking brake released.
The rear wheels must be raised off the ground or the driveshaft disconnected when the transmission if not operating properly, or when speeds of over 35 mph (56 kph) will be used or when towing more than 50 miles. (80 kph).
Do not attach chains to the bumpers or bracketing. All attachments must be made to the structural members. Safety chains should be used. It should also be remembered that power steering and brake assists will not be working with the engine off.
Remember that the power steering and power brakes will not have their power assist with the engine off. The only safe way to tow is with a tow bar. The steering column must be unlocked and the parking brake released. Attachments should be made to the frame and to the bumper or its brackets. Safety chains are also required.
If your having issues again then it really sounds more like an internal problem and the new fluid/filter just delayed the issue some. I would suggest having the tranny diagnosed at a reputable repair shop to save it. There are a lot of internal components that can cause it to slip and there is no way to pinpoint the exact component without a diagnostic test run on it, sorry.
