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.
