well the low cost way to go first would be to try and change the trans fluids. If the problems still remains the it may be an internal problem

I have that exact same truck and transmission and My Transmission did the exact same thing about a year ago and there was some kind of snap ring inside the transmission that broke. I originally thought it had to be an electirical problem because the truck shifted fine until OD or if i turned OD off. The 4r70w is a light transmission and i would suggest you have a shift kit put in and they make a heavier kit to beef it up.. Sorry its probably not the new you were looking for.

your overdrive clutch hub has gone out/worn out.
It can be replaced or you could have the whole transmission re-built or replaced with a low mileage one from the salvage yard , etc at a lower cost..(which is what I did)
This is common on these trannys.

sorry to say this trans has to be removed and rebuilt seems like od clutches burnt out-do you tow heavy trailer with truck as you have to tow with od off(push button on shifter)

Overdrive is electrically controlled by the pcm. When it's cold you need to check to see if the pcm is grounding the overdrive solenoid. If it is the solenoid might be bad or if the pcm is not grounding it then you need to check items that would cause the pcm to lock out overdrive. Coolant temp, TPS, Vehicle speed sensor, ECT. You will have to have it scanned to do this.
