I recently acquired a 1996 ram with Auto trans. The trans doesn't seem to be slipping but shifting from 2nd to 3rd is about 1000 rpm's high andjerky. The rest of the gears seem to be fine. Also, I don't think it does it if I turn the over-drive off. Does it need adjusting, fluid & filter change, or a new tranny?

Secondly, I changed the factory stereo with an aftermarket CD. The rear speakers aren't working right. I am getting some sound from them but it is quiet. I have to turn it up real loud to hear the rear. The front speakers work fine. I have no idea about this.
