Hello
As you guys all know , Ford's 6R60 is a licensed ZF 6HP26 copy with minor changes.
So most of the parts and solution are the same.
In my case , no any TCM KAM reset and adaptations relearn wont fix the 6r60 2to1 gear annoying bump.
Talking about ZF gearboxes , the solution to the bump is to replace the whole valve body seal kit ,includes bulk sleeve and transmission pump adapter and rubber bushings (every 100000 miles approx)
According to ZF repair manuals ,this seals cause pressure (mechatronic to gearbox pump seal )drop and as a result cause valve body solenoids harsh behavior.
KAM reset and adaptation helps to align the valve body pressure to the drop for a while until the seals fails finally.
So ive decided to do the job .all the valve seals for the 6R60 are similar to the ZF (includes the rubber bushings).
1. Take the valve body off the gearbox (thick head only T27 and T30 torx holds the mechatronic to the gearbox,do not touch the rest of the screws.)
2. Be careful with the mechatronic weight and put it aside when seals replaced.do not touch the electrical connectors.
Take the adapter and the sleeve bushings apart and replace.see the old and the new seals below .new fresh sleeve bushing should protrude approx 5 mm .ford dont sell this tubes , so ZF tubes are purchased,they are all similar to ford tubes.old tubes was crushed and kinda hardened relative to new flex tubes.be careful not to scratch the housing when taking the old tubes apart.
**The old rectangular seals shape are similar altough the old one looks shorter in the photo.
Torque to specs. 7 qt of mercon will be needed.
