Transmission shifts good when cold but once it warms up it will shift hard sometimes, after a stop it appears to try and take off in a gear other than first and then will down shift to first.
Had two codes P0766 SSD or SSPCD preformance stuck ( shift solenoid pressure control D) and P2705 Transmission friction element D apply time range or performance.
Question is it worth the time cost to replace shift solenoid D to see if it solves the problem or am I wasting my time and its time for a rebuild.
On that note my dealer says he can sell me a ford reman trans for about 2700.00 then I would have to install it or have it installed, with a 3 year unlimited mileage warrenty.
Local shop is 2400.00 with a 12 month warrenty.
or see about having a sun coast kit installed.
07 F350 CC long bead 180000 miles on it.
Plan on keeping this truck for a lone time.
We have the truck for pulling a 10K lb boat.

Note the scan gauge will not pick up the P2705 my repair shop pulled that on out with their reader.

 

Bumping back to the top. I would look at doing the solenoid first.

 

Do you have the diagrams you need to locate and replace that solenoid?

 

I have it in a trans shop now. they are going to check it Monday.
But from what I have been able to find it is most likely a bad clutch plate slipping causing a time delay and that is causing the shift valve d error.

 

Nothing in the clutch can cause a shift solenoid performance error. That code is set when the PCM commands the shift solenoid to change, but it doesn't change. The PCM can monitor the armature in the solenoid. A slipping clutch can't affect how the armature in the solenoid moves. A sticky armature can and will cause a clutch apply time error.

 

So the PCM knows how far and how fast that a solenoid moves when a certain voltage is supplied? That is it has a way to know the actual movement of the solenoid and not just looking for the result that should happen. that being the transmission turning the proper speed and the truck moving the proper speed for the gear selected and the rpms applied.

 

It can and it does.

When the armature moves inside the coil of the solenoid there is an voltage inducted into the coil windings. The PCM is able to detect and read that induced voltage and translate it into a movement. That is how a solenoid performance code is generated. It is the only way that code can be generated.

 

So with everything that has been said. I guess the question is.
Is the shop trying to sell the OP a rebuild that he does not really need?

I haven't seen the truck, so I can't say for sure. From what he's posted here, yes, they are selling a rebuild that isn't needed. The problem with the solenoid will cause the clutch code. A problem with the clutch cannot set the solenoid code.

 

They haven't said that it's needs a rebuild yet they are supposed to check it out Monday
