Truck: 03 FX4, 4.0L with an auto tranny. ~97,000 miles.
So I'm having all sorts of issues with my truck, and I think it's all pointing toward the transmission.
It started with me noticing what I thought was a hiccup/stumble. It felt as though the truck was kicked in the back end. It ranged from mild to pretty bad, with an audible 'clunk'. This seemed to only happen when the outdoor temps were below 20F.
I do intend to do a filter and fluid change, and hoping that it tames this and my next problem:
Tonight on my way home, I was stopped at a light and felt as though the truck was trying to surge. When I got home (a couple miles away), I played around with it in the driveway a bit. When I shifted from drive or reverse to neutral or park, the idle would drop to 400-500 rpm, and it seemed as though the truck was about to stall out. If I hit the gas, it'd drop back to an idle around 700.
I pulled the IAC and cleaned that tonight, as well as changing the engine oil. After I finished that, I played around with the shifting a bit. This is what I found when I shifted:
1 or 2 --> N/P, no change.
D or R --> N/P, idle dropped.
It almost seems as though the transmission is hanging up and not fully disengaging. Does this sound at all plausible? I know that without changing the fluid and filter, it's hard to pinpoint anything, but is there anything else I should try looking for?
