Advise needed: 2017 trans issues , bad lead-frame?

[dkincaid32]

2017/170k miles

Just started having transmission issues and wonder if any/all of this can be the lead-frame and am seeking the wisdom of the group.

- Had intermittent no-start that got worse after a month and would finally start after moving shifter around
- Keeps throwing P706/707 codes
- Reverse CLUNKS when going to gear
- Transmission at first would not downshift on the highway (60pmh @5000rpm) in any mode (D/M/2/1)
- Transmission then would not upshift like it just stays in 6th now and you gotta kind of spool the engine up to get going
- Tow/Haul just came on and wont go off
- And finally... none of the position lights (RNDM21) on the bottom center display illuminate when selected

Perhaps unrelatedly; the stupid "Cross-Traffic 'see manual' and 'wrench'" appeared just about the same time

On my 2015 limited I had to replace lead frame. Code was p0722 output shaft speed sensor circuit no signal. Had the wrench display in the dash, vehicle went into limp mode. I could pull over switch off engine then restart it would be ok for awhile. Then next time I stopped at a store got in to take off same thing again. Changed lead frame now ok. $1100 out of pocket. Around 83,000 miles when it happened. No help from Ford. Took 3 months or longer to get it fixed . Dealer said over 17,000 lead frames were on backorder. Finally went with aftermarket lead frame with same warranty as Ford. Would have taken 6-9 months to get part from Ford. Tried to get Ford to issue a recall but no success.

Our 2013 King Ranch 180+ went into limp mode and wrench display pulled over restart and would run for a little while and started downshifting and upshifting. Took to transmission shop pulled no codes with scanner he suggested to service transmission and added additive .Everything so far so good at 188,000+ so far
