Need a little help.

Installed the Revmax valve body on my 2018 RAM and was very careful with the solenoid pack.

I installed and made sure the slide was all the way back toward the plug of the valve body. Slipped right in.

When I went to check to make sure it was working truck says vehicle is not in park.

I tried going to drive and back.

No trouble codes.

Need a few trouble shooting ideas if anyone has experienced that.

The truck only has 28000 so I wouldn’t think the solenoid pack is bad.

It’s gotta be something simple I’m missing.
