#3276 of 3348 Re: 2002 Explorer noises [2002explorer]
Nov 20, 2007 (4:43 pm)
I figured out what this buzz is - Only when cold - It is in the transmission main control unit (vavle body). It is fluid making a vibration in the valve body only when cold. I was taking my 2002 explorer in for the last inspection - prior to the extended warrante expiring. Ford could here the buzz, but they could not figure it out... This was really annoying me, they could hear it, but could not figure it out.
Found a TSB # 01-22-3 that covered it. Dealer ordered parts - Will update once the valve body is changed. See the TSB attached below.
A/T - Buzzing Noise When Torque Converter Engaged
^ NOISE - BUZZING NOISE FROM THE
TRANSMISSION WHEN THE TORQUE CONVERTER
IS ENGAGED - VEHICLES PRODUCED 11/15/2000
THROUGH 11/11/2001 EQUIPPED WITH 4.6L
ENGINE AND 5R55W TRANSMISSION ONLY
^ TRANSMISSION - 5R55W - BUZZING NOISE FROM
THE TRANSMISSION WHEN THE TORQUE
CONVERTER IS ENGAGED - VEHICLES PRODUCED
11/15/2000 THROUGH 11/11/2001 EQUIPPED WITH
4.6L ENGINE ONLY
Some vehicles built prior to 11/11/2001 equipped with 5R55W and 4.6L engine, may exhibit a buzzing noise when the torque converter is engaged and the transmission fluid temperature is between 38-66°C (100-150 °F). This may be caused by a high velocity of fluid flow in the Main Control.
Verity that the condition exists using the procedure listed. If the conditions described are verified, the Main Control will need to be replaced. Refer to the following Service Procedure for details.
NOTE THIS ARTICLE DOES NOT APPLY TO ANY OTHER CONDITIONS OR COMPONENTS THAT MAY CAUSE SIMILAR SYMPTOMS.
1. To verity that the condition exists with the vehicle, first connect a tachometer to the engine if the vehicle is not already equipped.
2. Install an NGS or equivalent and monitor the Transmission Fluid Temperature (TFT).
3. Start the engine and drive the vehicle.
4. When the TFT reaches 38°C (100 °F), maintain a constant speed of about 80 km/h (50 mph) to engage the converter. Tap the brake pedal with the left foot. Engine RPM should increase when the brake pedal has been tapped, and decrease after about five seconds after the pedal is released.
5. Maintaining a constant vehicle speed, allow the torque converter to re-engage.
6. Listen for the Torque Converter Clutch buzzing noise. Is the noise present?
^ If yes, continue with the verification.
^ If no, follow normal diagnosis as listed in the Workshop Manual, the Main Control is not the problem.
7. Continue to bring the transmission to operating temperature above 66°C (150°F). This may be accomplished by driving the vehicle for 15 to 20 minutes.
8. After normal operating temperature is reached, maintain a constant speed of about 80 km/h (50 mph) to engage the converter. Tap the brake pedal with the left foot. Engine RPM should increase when the brake pedal has been tapped, and decrease after about five seconds after the pedal is released.
9. Maintaining a constant vehicle speed, allow the torque converter to re-engage.
10. Listen for the Torque Converter Clutch buzzing noise. Has the noise disappeared?
^ If yes, continue.
^ If no, follow normal diagnosis as listed in the Workshop Manuals, the Main Control is not the problem.
11. If the condition exists, drain the transmission fluid from the pan.
NOTE AN IN-LINE SERVICE FILTER IS NOT REQUIRED TO BE ADDED OR REPLACED FOR THIS ARTICLE.
12. Replace the Main Control 1L2Z-7A100-CA and Fluid Filter 1L2Z-7A098-AC. Follow the steps listed in the Workshop Manual, In-Vehicle Service, Main Control Valve Body, to remove and replace.
13. Verify the condition has been corrected.
14. Clear all DTCs

I noticed the same crack on my 04 Mountaineer, just under the middle liftgate window cracking down to the top of the emblem, down the right side of it. Any knows easy fixes?

My daugher has the same crack in her 2003 mountainer. She took it to the dealer, and they said it is very common on the 03 mountainer with around 38,000 miles. She has 39,000 miles and missed it being covered under the warranty by 3,000 miles. The dealer also stated that the crack will spyder after a while, and Ford should have a recall, but they don't at the present time. They told her to dispute it. If she doesn't get anywhere, maybe she will start a class action suit, because it is definity a defect.

I also just noticed this crack about a month ago, figuring what I did to have it crack like that, but now reading these posts, it definatley must be a defect. My friend was a mechanic for a ford dealer, He said we should call the ford hotline and put in our complaints, that could trigger them to do something about this issue

I'm having the same issue with my 2003 Mountaineer and can't figure it out. I am nervous that since the dome lights and side view mirror lights won't go out, it's going to kill the battery. I think I'm okay with my door switches (haven't had a problem with those yet) but have you had any resolution with this? I noticed you posted over a month ago-- How'd it work out?
#3283 of 3348 2004 explorer lift gate crack
Dec 24, 2007 (9:37 am)
I came out one morning to find a crack on the lift gate on the right side of my ford emblem. I could not figure out what happened. Since then I've seen 4 other Explorers and or Aviators around the same year with cracks some on the right and some on the left of the emblems. I think I will call Fords Hot Line

It hasn't been resolved yet. I believe it may be the GEM (generic electronic module); however, my mechanic said it is easier to diagnose and repair when the module completely fails so they don't have to go through the hassle of ruling everything else out before diagnosing GEM failure, which I guess is the only way. I don't believe it will kill the battery because the lights go out after about 10 minutes - the same length as the accessory delay, which no longer works in mine - probably because of this bad module. I've got the original battery in my 2002 so I don't think it's being affected. I'll keep this updated if I learn anything more. For now, I just deal with it and try to ignore it - although people are CONSTANTLY doing a good deed and telling me my dome lights are on

I know, I have a feeling I am going to be hearing a lot of the same thing from people about the dome light!
What other things does the GEM control so that I can be on the lookout for anything else that may fail in the future? I imagine it would be pretty much all of the electronic functions in the dash, right?
