Went to lunch, stopped at an intersection, waiting on traffic. Traffic clears and I start to accelerate, but no go. Check shifter, truck is in D, give it the gas again, and it catches and takes off. Did it a couple more times. Haven't had this happen before. Gonna check fluid when I get home. What are thoughts? Electrical, valve, solenoid? This is new to me.

 

Hopefully is just low fluid level. Other alternative is not good.
