Transmission Shifting Issues

You need to drive the truck and get back to us.

If the gas pedal is being operated with considerable enthusiasm and gusto, the transmission will not shift when expected. If the gas pedal is on the floor, the transmission will hold the gear for as long as it can tolerate it.

I don't mean to suggest that your son pushes the pedals too hard, but if he does press them too hard, then the result can easily be that the transmission holds the gear longer than you might like.

If there is a fault, the OBD II Scan Tool should be able to pull it for you. Odds favor this would trip the Check Engine light, but maybe not. You can use the scan tool for free from Autozone stores. Depending ou where you live, either they will pull the codes for you, or they will give you the scan tool and you pull the codes yourself. It's very easy to pull and reset the codes.

You will find the data port along the bottom edge of the dash board. Plug the scan tool in and set the ignition to ON but not START. The codes will be displayed on the scan tool. Make a list of the codes that are present, then reset the codes.

Drive the truck and see for yourself what the conditions are that make the transmission hold the gear for too long. Then, pull codes again and see if there are any that are on your list from earlier.

If the transmission holds a gear to 4k on the tach, then you have to determine if it is related to a specific gear change or all of them.

I think the O/D light would be flashing.

That too. Or, maybe instead ...

I'm not sure. I'll have to check, but I think there can be transmission issues that appear as an OBD II trouble code and others that appear as a flashing O/D light. Either way, it makes sense to me at this juncture to pull codes, jot them down then reset them. Then if the problem manifests itself again, pull codes to see if there are any repeats that also deal with the symptom set.
