I have a 1997 Ford f150 4 wheel drive 4.6 l engine I change the intake gasket and now all of a sudden I got no drive won't start with the key I got reversed four-wheel drive works and takes reverse but no drive no lower gears nothing and it just all of a sudden done that I retraced all the wires nothing fluids fine so I don't know what the issue could possibly be could it be the little box that mounts the electrical box .... Any help would greatly be appreciated thanks again
My '99 Explorer 4x4 4.0 V-6 got the opposite problem a few months ago. Trans, overdrive, and 4 wheel drive continued as before but reverse gear was same as neutral - except on level ground it would creep a couple of feet backward sometimes. I just got used to only parking facing uphill, so I could let it roll backwards in neutral when I left.
After a month or so of that, I was slowing down for a right turn, when at the moment when it usually shifted to low (10mph), I heard a sound like a wheel bearing grinding, so I put it into neutral, and coasted to a stop at the right shoulder. I looked underneath at the U-joints, etc - saw nothing wrong, so I started it back up and put it into drive. Nothing happened. But when I put it into "2" (second gear?), it did fine.
At this point, I had 3 neutrals: "R", "N", and "D". Then I tried "L". Nothing happened (the car didn't move). That is 4 neutrals, a "Park" (P), and a "Go" (2). A few days later, I discovered that "D" (drive) works fine if I shift from "2" to "D" only after I am going 20 mph or more. It even goes into OD on the freeway. But if I go under 15 or so mph, it shifts into neutral. That's fine if I am stopping, but I have to shift to "2" again when the light turns green.
Does anyone have any idea what I should check or replace, and whether this problem will get worse? The Explorer has 225,000 miles, and is on its second motor. Long before losing my reverse gear, I noticed that it freewheels (coasts) downhill in "L" but not in second. Does that mean it has a bad carrier one way clutch or a loose reverse band? I understand that there are 4 solenoids in or on the transmission. Should I have the fluid and filter replaced, and look for a bad solenoid? Could it be the torque converter?
