Truck wont go...transmission or something else?
Here's the issue,
-Truck runs to about 2500 rpms before it'll shift under 1/2(normal) throttle
-At 65mph on the highway, with just enough throttle to maintain speed(mostly on cruise), the truck is turning about 2300 rpms and it running at 4 psi of boost.
-When i shut off cruise/let off the throttle the truck decelerates quickly from 65 to 50ish. Usually under 5 seconds give or take. Feels almost like the brakes are on?
-No brake smell at all, nor is one wheel really hot after driving 25 minutes to work. Had brand new warn hubs installed less than a week ago because the hubs wouldn't turn from auto to lock. I thought the hubs may have been the issue but turns out they weren't. Bearings were in good shape too. I didn't change anything on the rear axle, yet. Could this be something with the trans? PCM maybe? Anyone else ever experienced this problem? Front rotors are warped but I plan on changing those out too. I dont see warped rotors causing that much drag tho. Whatever it is, it's killing the mpg too... HELP! Thanks guys
Could be I'm a total idiot and there's nothing wrong, but the truck never did this before and it seems like the engine/trans are working much harder than they need to be/should be.
Enough with the stacks already...
