Ok, so I received the fax describing the new TSB #11-8-21. I will try to translate the important points. It is actually the TSB that will replace the 11-5-6 that many of us had performed. It addresses the Edge, MKX, Flex 2009 and the Edge, Flex, MKS, MKT, MKX and Taurus 2010-2011 produced before April 15th 2011.
Those ones which experience an hesitating or slow acceleration from 0 to 5 mph followed by a harsh bump or feel like slippery from a stop followed by a harsh bump.
The intervention only affects the gear box MERCON LV.
A new «calibration» is available and there is a modification in the hydraulic block of the gear box to correct the situation. The mod consists in removing one hole in the intermediate plate of the hydraulic block and remove a «holding ball» in the same area where the hole was removed...
If the previous steps are not done properly, new symptoms like difficulty to put on reverse and sudden acceleration when shifting from 2nd to 3rd gear...
1 ) Reprogram the PCM with newer version of calibration 73.04 not included in the DVD VCM 2011.5, but available on
www.motorcraft.com
2 ) Place the hydraulic block of the gear box according to chapter 307-01.
3 ) Replace intermediate plate of the hydraulic block. The X identifies the hole that needs to be removed (missing image)
4 ) Remove the «holding ball» identified by the X (missing image), leaving 6 holding balls...
5 ) Replace the block
Under warranty 11081A = 3.1 hours
Code for the dealer :
Base reference 7A100
Observation code : 42
There you go, hopefully the new calibration from 11-5-6 to this new 11-8-21 will be correcting the issue that I and others may still have, even after 11-5-6 was performed...
Cheers!
Steve
P.S. Hopefully my translation was helpful... not obvious to translate mechanical terms, especially when I don't even know what they mean in French lol!
