my friend has a dakota 2wd with the 42RE transmission. He used to be a tech at the local chrysler dealership and did most of the transmission work for them. he just rebuilt the transmission because of a shifting problem but it didn't fix the problem. The truck has 2nd gear and 4th gear but no 1st or 3rd. He said something about it being the gov pressure sensor and solenoid. Are there any other things that could cause this? I'm thinking about grabbing a powertrain control module at the JY tomorrow too. Any other ideas?
