Won't Engage in Drive When Hot
Haven't posted in quite a while. I hope everyone is doing well.
I'm having a tranny issue. At first it was just an intermittant thing but now its happening all the time, so I want to take care of it. When going from Park or Reverse into Drive, the truck won't engage in gear. And for some reason it only happens when the truck is warm. If I let it sit for a few hours or overnight, it will engage fine in the morning. At first, If I just dropped it down into 1st, it would engage and then I could move it back to Drive, but now, even that doesn't work.
Took the truck to Ford and the tech said he found a sticking valve in the valve body, so they put a new valve body on and the problem is still happening. They also checked a TR sensor? (I don't know much about transmissions) and they said it seemed fine. They also said that there were no shavings in the fluid and that there were no signs of any serious problems with the transmission itself.
So, the problem is still happening and the dealership manager says the ONLY other thing it could be is the piston. Once the truck engages, it runs and shifts just fine.
I just wanted to run this by the forum before I give the go-ahead to tear it down and replace the piston. Does this sound consistent? or are there any other ideas out there?
Thanks in advance.
