I have a 89 chevy 4X4 truck with a 350 & a 700R4 trans. I recently lost overdrive and drive after driving for approx. 1 hr. I let the truck sit for an hour and the trans opperated fine with the fluid cold. do i need to rebuild/replace the trans or can i just change the fluid and filter. The truck has 113,000 miles on it. ---

Sounds like limp mode. I’m no tranny expert, but losing drive and overdrive at any point for any amount of time isn’t usually something that a fluid/filter change will correct. Is it doing this every time the fluid gets hot enough? ---

It only did it the one time then i pulled the pan and the fluid smelled burnt and was dis-colored (orange-ish not red) ---

Yikes. Burnt-smelling fluid means it’s overheating badly and is probably sustaining damage. I’d get it to a local transmission shop and see what they can do for you. Try to find an independent rather than a chain store.
