No Hold Back
I'm new to this forum and I could use a little help.I have a 2001 f250 diesel 7.3 4x4 with banks trubo.To shift in to four wheel drive I turn a switch on the dash. I just bought this truck and don't know a lot about it. When going down hill there is no hold back if I take it out of OD my tack falls off to 700 rpm if I pull it down to second the tack stays at 700 rpm and the truck is freewheeling. I think that there should be a little hold back. Also there is a whinning noise that starts at about 30 mph and gets louder as speed picks up.
Thanks for any you can give me
Tolong
