Is there anyway a faulty PCM (powertrain control module) can make a 5R55W transmission fail? Such as the losing high gear and destructing the high gear band? The engine is running fine still and the problem originated when I was cruising down the highway and all of a sudden lost OD and 5th...

About 2 years and 16000 miles ago I had my Ford Dealer install a factory rebuilt transmission in my 2002 Explorer. Last week, while on a road trip I lost overdrive and 5th gear. The dealer in the closest town said they would need to remove the transmission and go from there. I had my elderly...

I recently changed the rear differential fluid and didn’t know I was supposed to use Teflon tape or RTV to seal the threads. Now I have an irritating slow seep that leaves spots on the garage floor. Is the plug thread ¾” NPT? I was thinking to buy a PVC pipe plug so that I can do a quick plug...

I'm planning to change the Transfer Case fluid in my 2002 Explorer 4x4 and want to put in Mobil 1 ATF fluid. It is Mercon rated which is what Ford recommends for this Transfer Case. Has anyone already done this? Any problems? Thanks!

Getting ready to change the fluid in my 02 Exp XLT with LS rear end. I noticed that Mobil 1 already has the friction modifier in it. Does it have enough or should I go ahead and add the XL-3 friction modifier? Also saw that Autozone has CRC friction modifier for LS diffs. Is this an OK...

There is a coolant hose, maybe 1" in diameter, that goes from the bottom of the overflow reservoir to down underneath the the radiator on the same side. From there it connects to a metal tube were it crosses along the bottom of the radiator back into another hose that then connects into the...

In the last week I have noticed that my ’02 Explorer – V6 makes a brief loud rattling noise during a cold start-up. When the engine is warm, it restarts normally. I am wondering if the oil filter has an anti drain back valve, and that it has failed? My other car has an ADV equipped filter...

Kind of an off the wall question, but what the heck. Maybe some of you guys have already given this some thought. In addition to supplies for an oil change, spare coolant and tools, what do you think I need to have on hand to keep my Explorer running in a survival situation for a trip from...

My maintenance manual says the ball joint and swing arm are and integral part and you have to buy the arm and joint together as one piece. But my local AutoZone has the ball joint available with some loaner tools to push the joint out of the arm. Is my manual wrong? I sure hope so because I’d...

I am getting the parts together to change the front and rear pads on my 02 XLT 4x4. The manual says the stainless steel “slippers” should always be changed when new pads are installed. The slippers look to be some kind of a shim that fits on both edges of the pad. Anyway, the pads I bought...

I did a search on this topic but did not get any hits. I need to install new brake pads on my 02 XLT 4x4 w/ heavy duty towing package. The parts list say pads for single cylinder calipers and two cylinder calipers are available. How do I figure out which calipers I have? Thanks!

My 2002 Explorer has a squeak when I push the brake pedal. This is not a metal to metal squeak, but metal to rubber one. I have already lubricated the actuator shaft that pushes into the master cylinder, ahead of the external rubber baffle, with silicone lube. You can see the rubber baffle that...

I changed the fluid on my 5R55W transmission this weekend with some surprising results. First of all, when I drained the pan, I got only 3 to 3.5 quarts out of it. I had read were it should take 6 or so to do the job. So, I put 6 quarts in through the fill plug on the side of the...

I have a 02 Explorer XLT and a simple question, I hope. What does the switch do that activates when you open and close the hood? The switch is located on the left side of the engine compartment, right above the passenger side front wheel. Thanks - Brad
