Hello,
I am from Poland, and i can make sOme mistakes in words, sorry. :lol:
I bought a Jeep with an automatic transmission error. the predecessor probably replaced everything he could - pressure sensors, control panel, solenoid valves.
The first error P0841 pops up and then P1775. The box was dismantled, no filings, clean oil, filters too. After storing the error, the gearbox works perfectly, until an error appears. Sometimes I will do 300 km and it's ok, and sometimes 5 km, but then I remove the error and it's still going well. I will add that in rainy weather the error pops up much faster.
Three mechanics tried, but failed and apologized for making the hope.

Closely check/inspect all the wiring between the transmission and the TCM (transmission control module). Look for any chaffing or rubbing locations on the wiring harness.
Check all grounds and make sure they are all making good contact and and are tight. Several on ground location behind left front headlight on top of inner fender liner. One near TCM on passenger side. Bad or weak grounds can cause some really strange happenings on electrical systems. :wink:
also, disconnect the connector from the TCM and inspect all the pins on the TCM and look for any that are discolored or look different from the rest.
If you find a discolored pin, lightly sand it with some fine sandpaper and closely inspect the connector socket (female side) for the one with the discolored location.
