Hello, I'm trying to figure out what is going on with my truck. It's a 1995 1500 4wd and it just started acting up last week. I noticed it wasn't shifting into overdrive and it was very slow from a start, almost like it was slipping. I checked the fluid and it's right where it should be when hot. It shifts fine when I first drive the truck cold but once it warms up and I downshift for a light, it's acts up and that's what throwing me off. I have been trying to go through all of the information on this site but there's a ton. I see that if the shift a solenoid fails, I would lose first and fourth. I just want to confirm that I'm on the right track before I just shotgun parts. Any help will be greatly appreciated! Thanks!
