The

's GX (2014 base mdl) started this issue last summer.
This thread showed me how to clear the codes and got us home from the Finger Lakes, so thank you.
She refuses to drive in manual mode, she's doesn't like the feel and is afraid of over revving the engine...But she will wield a 10mm wrench and clear her own codes so she can get home from work.
I am in the middle of the Sonnax Zip kit install. "Just" have to drop in the check balls and reassemble everything.
There is a discrepancy for one check ball location in the Sonnax instructions in the upper valve body. The gasket plate between the valve bodies doesn't lie though and confirms proper placement.
Just want to say that if anyone else is contemplating this, you need to get a tub of Assemblee Goo, the green not the blue. It's the high tack stuff.

Learned about it from this video :
. absolute life saver, no mention of the this stuff in the FSM.
This video at 19min, shows where one of the keeps lives that falls out and is not obvious where it came from...cost me and hour plus of chaos management.
You will need this to "goo in" 3 keepers that are not under tension from the spool valves and the Spring Ball
that will fall out of the transmission when you pull the valve body. There is no way to install this without the Goo unless the transmission is out of the rig and upside down on a bench. There are also three grommet seals that need to be gooed in place to the trans before valve body reinstallation and three 4 accumulator pistons. 3 of the 4 have o-rings and should stay in place, but I'm not going to trust that. and the 4th is a slip fit and if not gooed in, will not stay. Gravity is working against the assembly.
This is not a job for the faint of heart. I'm a degreed ME and design and manufacture machine-guns for a living...this job has made me question my choices a couple times.
I'll let you know (or rather my wife will let me know) if this gets rid of the codes.

Hands are warmed back up enough, back to the garage....
