    Need input before I change my transmission fluid.

    Yeah, I've seen images of the plug. I'll keep an eye out for it. Thanks for the info.

    Need input before I change my transmission fluid.

    I know there is plenty of discussions on this topic but I need a few questions answered first. My '99 5.4 Expy has roughly 156k miles. Half of which were driven by the previous owner and half by me. I have never changed the fluid and I have to assume that the previous owner did not either...

    What did you do to the expy today

    Today I changed my PCV valve assembly and the heater hose that I broke in the process (the damn plastic quick detach part broke off at the firewall when I lightly bumped it). Later this week, I plan to clean my MAF sensor perhaps give Gotts Mod a shot. I still am looking for the easiest way to...

    So I got the new PCV valve and hose assembly from the dealer. Only set me back $35. Unfortunately, when I was reaching around the intake to pull off the rubber boot, I bumped my heater hose and broke the plastic connection. It must have been very weak or brittle. So now I have another hose...

    I took a brief look at the PCV valve and the line that runs to the intake manifold. I found a small hole in the line just after the PCV valve. I wasn't able to get a view of much else. The line is pretty torqued and creased so I wouldn't be surprised if there were more leaks throughout. Is this...

    Hey guys, My CEL came on several days ago so I took it to PepBoys to have them pull the codes. I got following codes: P0171, P0174, P0156. I know that P0156 code means O2 sensor malfunction (Bank 2, Sensor 2). I read, however, that I should address the other codes before replacing the...

    Grinding and and clunk when coming to a stop.

    I'll look into the calipers and bearings, but to answer you question FordandPolaris, it doesnt seem to be coming from either side. It feels like its coming from roughly dead center of the vehicle. I imagine this is why my neighbor said it may be tranny related and my other friend said i may...

    Grinding and and clunk when coming to a stop.

    Yeah, for the most part. I rotated my tires about a month ago. The rotors and pads looked fine then. Then, about a week ago I started feeling the grinding and clunk. Obviously, I thought it was caused from something I did when rotating the tires. I checked the rotors again and there isn't any...

    Grinding and and clunk when coming to a stop.

    Recently I have been feeling grinding/friction and a clunk just before coming to a stop in my '99 5.4L 4x4 Expy. My neighbor said it may be transmission related and might be time to change the transmission fluid. Another friend vaguely mentioned greasing a joint..? Do any of these symptoms...
