Question about my instrument panel lights/hard shift around 20mph

[ford*family]

(6 Cylinders K 4.0L Flex Fuel SOHC)
*abs *wrench *brake * check engine *4x4 (flashes off/on)
Was told my throttle sensor was bad (reasoning of lights returning on after clear coding, and possible hard shifting), so had a friend change the throttle sensor but still hard shifting , and lights still on.. He stated to me that when he goes in to check the coding he gets locked out of my system he's baffled by it and I'm honestly running out $$ on "maybe" answers..
Does anyone have ideas or have had the same issues that was resolved..
Thanks..

Check your battery voltage with a multi meter. Pos probe on battery lug, neg probe on battery neg terminal. Make sure alternator is putting out 13.9-14.07 volts.

Do the gauges flash at any specific time? Or just randomly. Radio cut out as well?

Thanks for replying everything you mentioned was checked and working as should..
The gauges mentioned are constantly on,, besides the 4x4 this is the only one that flashes..
