I know it is the CDF drum that causes the issues - but is it possible that the valve body AND the CDF drum are the issues? and not always on the same trans?There is no curing the CDF bushing problem short of a major transmission rebuild. No additive is going to reseat the bushing and lock it into place.
I've seen a transmission repair video where the techs modify the drum to add a retainer ring that keeps the CDF bushing in place in the old style transmissions like early rangers have.
What I can't figure out is Ford has been using the 10R80 transmissions since 2017. Do all previous F150's and any other models that use the 10R80 have this same issue?
Answered my own question when searching for transmission info. Found this ambulance chaser who had details on the models.
I much prefer LubeGuard to a lawsuit.
ie my valve body might be gunked up and cleaning it fixes this for me (otherwise why is it a step in the TSB? [EDIT 2: or is that just a step because the engineers don't know what is really going on and needed to put something in the TSB before full rebuild/replacement?]) vs billy down the road who it does nothing and they have to rebuild his tranny. . .
it could also be that the butt dyno thinks it is fixed because the butt dyno "felt" the issue. . .
EDIT: I prefer that ford just admit there is a problem and fix all the trannies without a lot of run around. . . LOL ie I show up at dealer they test drive and the tranny is clunking and hard shifting etc - automatically replaced with a new tranny... I imagine it would be cheaper in the long run to just swap known good transmissions into vehicles instead of spending 5-16 hours diagnosing the issue and still having to replace the transmission...
