I have a 2012 ram 1500 express, hemi, 2wd. While driving it went into manual mode 4th gear. Park, reverse, neutral work as normal. A quick research shows the solenoid pack as the culprit. I'm having a hard time actually getting one (back ordered for the grey connector) I have 2 questions.

1. Will the white connector (older model same part) work, seeing as how its cheaper and more readily available.
2. While taking everything apart to change if and when the part comes in, I noticed the bottom side of the valve body has a lot of "spider cracks" concentrated around the bolts. Is this normal and is it a need to concern with replacement of that also? It looks like the factory torqued the bolts too tight, but I'm not a rocket doctor so I dont know for sure.
