The other day I was stuck in 4th gear, could not up shift or down shift out of 4th. I had to stop put it park turn off truck, then restart it and I had all my gears again. What would cause this to happen, what do I need to do to prevent this from happening.
I have read it might be a solenoid or maybe a valve body needing to be replaced.
Well the valvebody would need replaced because there is only one valve in it.Its electronicly controlled by the solenoid block which what might cause the issue.Have you had it scanned for codes?
