Hi my name is***** will be glad to help. This sounds like more than one problem you are having. Check the turbo intake piping for leaks and CAC and inspect the turbo for problems. As far as the transmission locking up, when does this happen? at a stop, idle, taking off in low gears, etc? Let me know. We can follow up as needed.

There is no leaks coming from the turbo. After removing foot from gas pedal, there is a suction noise (sometimes). Whenever that problem occurs, the shifting locks in gear. Then we need to shift to neutral, then rev, then put in drive. At times, if you hit the brakes too fast this problem can occur. This only occurs in higher gears. Both up shift and downshift don't work. Today I tested the truck, it didn't occur today, it occurs at random moments. It feels as if it's reaching for air and I'm not sure why because there are no leaks.
