I got a problem with my 2001 explorer sport transmission

[yeahey]

AAMCO says it has problem inside. The transmission has viberation when the RPM drops to 2000, but I didn't reduce gas. Did you guys have similar problems before? How did you solve it? How much cost? Thanks.:exporange

Could you explain the problem with a little more detail? How many miles do you have on your 5R55E 5 speed automatic? Have you maintained a routine fluid, and filter replacement regimen?

 

[yeahey]

yep, actually I went to AAMCO, they give me a free check and said:
1. no computer check error code
2. short delay between 2nd and 3rd gear, and something related to "reverse" something...
3. flare
4. TCC/Lockup: shatters (I don't understand this term)

What I found is:
1. some times when I step on the gas all the way down, the RPM will stay at 2000 for 2-3 seconds, and then go up to 3000. that's a apparent delay.
2. If I am driving at about 65MPH on high way, and I am holding my foot stepping on the gas, not forward, not backward, just hold it there, the RPM will drop from 3000 to 2000, and at 2000, I can feel apparent viberation down there, I guess it comes from the transmission. AAMCO also said so.

Can you help me with this problem? Thank you.

It might be related the TCC solenoid. The solenoid in your transmission is modulated (like the EPC solenoid), so it is considered a high wear part.

 

[yeahey]

Thanks. But I still don't know what to do, I am a new driver. Can you tell me like what kind of job I should get some people to do with the problem? And about how much am I going to spend? AAMCO guys asked for $1295 to "open the transmission and check and clean". I don't know if I should spend this money. Thank you.

What you feel as vibration is likely torque convertor shudder. The first thing I would do is change the fluid - all the fluid- flush it so it is totally replaced with new... make sure they use REAL MERCON V, not Mercon III with an additive.

I am betting your shudder will go away.

Then you need to look into the 2-3 shift flare. There is so much information on here about that I won't repeat myself except to say start in the "stickies" at the top and started reading about 2-3 shift flare there Plenty of links to help you get an understanding all about it.

DO NOT PAY AAMCO $1295. Once your trannie is out that will turn into $2500.

Start with a complete fluid change and make sure it is MERCON V they use to replace the old fluid. Let us know how iit is working after that.

 

[yeahey]

Thank you so much! I'll work on it!
