I've been through several wheel bearings on my 00 Ranger; they are a known issue with these model years. The best source for me has been a Florida-based outfit called Auto Parts Direct To You. http://www.apdty.com Here is a link to the 2002 Ford Explorer wheel bearing selector based on your Explorer's specs.

Note that Ford was inconsistent with the type of assemblies they put into these model year vehicles; I found that out the hard way by ordering online. You might want to give these guys a call and be sure you're getting the right bearing for your vehicle. I've found them to be extremely knowledgeable and helpful, and the big plus is the lifetime warranty they provide on wheel bearings... a huge bennie for Ford truck owners!

torq converter

The transmission service is performed by lifting the vehicle in order to get access to the transmission pan. Remove all the bolts that hold the pan in place and the fluid will come out when the pan is being lowerd. From there the filter is accesible and should be changed by simply pulling it downward. The new one is installed by pushing it firmly in place where the old one once was. Clean the pan of the transmission completely including the magnet. place new gasket around the pan and reinstall all the pan bolts. be carefull not to over tighten the pan bolts as it can damage the new gasket the you have put on. next, lower the vehicle and add fluid through the dipstick tube located in the engine compartment. It's best to add 4 quarts then start the vehicle and check the level. If more is needed, add accordingly.

There is none. To change the fluid you need to remove the cover - undo one end first to limit the mess - but yes, it's messy. AnswerBest To Have A Good Transmission Shop Do This. Sometimes You Can Miss Alighn The Filter On Some Tranmissions And They Will Go Out. About Changing The Fluid, Even If You Could It Wouldn`t Do The Job Without a New Filter. Good Luck AnswerThere is an excellent write-up on this procedure relating to a Taurus - the steps are the same.

NOTE: dropping the pan alone will NOT change ALL the fluids - specifically the fluid that is in the torque converter. That would require a shop to perform a full fluid change with their specialized equipment. Answerdrop the pan, replace filter, clean pan replace gasket torq bolts to spec. refill to warm line on stick

Install new filter and pan gasket and gently tighten bolts. Caution, if overtightened it will leak!!! Remember how tight they were when you removed them or get a spec & torque them. Refill the trany through the filler tube, DON'T overfill it or it may not shift properly. To check the fluid level the vehicle needs to be running in park and on a level surface. If you do the above you will only change aprox 40% of the fluid. The torque converter, cooler & lines hold the rest and the fluid won't drain out of them.
I suggest you take it to a shop that has a trany FLUSHING machine and will exchange 100% of the fluid and do the filter & gasket at the same time. Add a bottle of seal conditioner when done. With the price of a new trany this should be done every 80,000 kilometers (50-60,000 miles) or check your owners manual for service intervals. Not a lot of shops have this machine so be selective. Might cost up to $200-250.00 for this service to get it done properly but a proper trany rebuild can be $1500-3000.00 or more in some cases on some vehicles.
Flushing the fluid?

But the system should be flushed. Just dropping the pan and draining the oil and changing the filter on your transmission leaves all the used fluid still in torque converter. Have the system evacuated and totally replacing ALL the fluid is a much better approach. It will cost you more but if you plan on keeping the Ford, it's a worthwhile investment.

I would take it back friend. They are many people that work on these, replace the seals, put it back in. Maybe get another person to look at it and see if it is a rebuilt one. Take it back.

Might be best to have a transmission place look at it
The error codes indicates a problem with an electrical problem with the Torque Converter Clutch Circuit

well i have the same explorer that you do and it is my first ford i have the same thing this is after doing the rear end 1200$ trany was 1000$ transfercase was 1100$ and now it is doing the same as yours in my oppin ford exploders are **** i will never buy one again sorry for your problome but ya yours 1000$ to 1500$ fords exploders ****!!!!!

How many miles does it have on it? Also has it had trans work before? These transmissions are know for having lots of valve body issues. IF you are light on the throttle it works fine?

possably a baring inside your gear box, if you know how 2 change a gearbox, good stuff, but first take it to a garage to see if they can pick up on it, before you do any work

Sounds like either the torque convertor or the Modulator valveto me. Steve in the UK

If you are trying to remove the crankshaft you will have to pull the whole engine,Unfortuneately the crank shaft is also connected to the trany through the flex plate which is the piece that tranfers the power from the engine to the torqe converter which is part of the transmission.
