From a stop my transmission wont shift up. Changed fluid and filter, no change

Not sure if this applies to you, but the transmission is probably electronically controlled. Check the electrical connections or there may be sensors in the transmission itself that are going bad. Restarting is probably resetting the signals in the computer allowing it to operate for a short time. Understand, this is a guess on my part as I'm not familiar with the make and model you have.

my charger is doing the same thing did you ever figure out the problem?
