If I understood right, they just made the switch to the BorgWarner solenoid after some testing. My new trans has the BW in it, and I just received it Wednesday.
The new valve body comes complete with solenoids. The governor pressure solenoid and governor pressure sensor are new factory Dodge parts.
I'm gonna email him these pics and see if he can verify if it is a stock solenoid and see what he suggests..........looking to upgrade to either the heavy duty Borg Warner or do the Gm Conversion
Craig from GB said this about my truck's valve body:
"If it was 2 years ago it would be the stock gov solenoid. We started using the BW about 9 months ago."
You are correct. I've been talking to Craig the last little bit working out an overdrive (or lack of) issue. During the conversion I asked if he used OEM or Borg. He said they have switched to Borg Warner instead of the OEM Solenoid.
