I am looking to see if anyone has installed the Sonnax CHR145 universal valve body in their 68 or 66 RFE using the original grey connector solenoid pack, if the truck is 2011+?
The CHR145 is the same unit as the CHR146, but sold without the solenoid pack. The 146 includes a white connector solenoid pack used with valve bodies with the 7 check balls. The 145 and 146 are both identical 7 check ball units, but the Sonnax literature states the 145 can be used with any color pack with no additional changes.
Conventional wisdom says that the grey pack cannot be used on a typical 7 ball valve body due to the lack of an OD solenoid, but the white connector can be used in all cases.
Long story short, I had some issues with my 145 SKU a while back on install, resulting in limp mode with a P0871 code for OD pressure fault. I am trying to determine if they’re incorrect in saying any pack can be used or if I just had a defective unit.
