I have a 99 5.2 D. When the truck sits for awhile or over night the transmission will make a whrrrrrrr noise until it goes into third. it does make the trans slip or shift funny it just makes that noise. just wondering if this is something i should be concerned about now

 

Hello,

I hope alot of people read this because this is common problem in Dodge rear wheel drive tranny's 96'-08'. It is a defect from the factory. The inner seal in the direct drum(which is for 3rd) is to small. While it is new it seals fine, but over time wear from the piston applying and releasing, it wears it down enough for fluid to blowing by it. The noise you hear is the fluid blowing by in between the rubber lip seal and the aluminum piston. It will still apply because of pressure, but just slower causing the slip. Transmission's that this envolves are the 42RE,44RE,46RE,47RE, and the 48RE. On a rebuild the new updated lip seal comes in the kit we buy and gets installed and no more problems. Hope this helps.

 

Hmmmm, I wonder if this may have been my problem with my D not shifting into 4th after warming up. As long as I got onto the highway before the tranny was warm it would shift into 4th (and stay there just fine). After warming up I was locked out of 4th altogether so once I would stop I would no longer have OD.
