Anyone deal with transmission code p0741?

[North Idaho 5.oh]

Driving down the road and noticed my O/D light flashing…. Looked it up and came up with p0741. Something to do with the TCC solenoid? I know this is a loaded question somewhat… the engine and trans are low mile from a 2000 explorer (302/4R70W)
My question is …. Who has experienced this and what did you do to remedy the situation? Fingers crossed I don’t have to drop the transmission and replace the converter

Is the TCC solenoid accessible without pulling the transmission? Might be as simple as replacing that solenoid. I have no idea honestly, not a transmission guru by any means...I just know when they work great, when they don't, its expensive.

The TCC solenoid is accessible just by removing the pan, and that’s where I’m going to start. Then obviously going to do new filter, gasket, fluid. Going to also use some trans doc Lube guard. Just not exactly wanting to drop the trans to do a converter right now since I have all these other projects going on. If the TCC solenoid doesn’t fix it then I’ll just nurse it along till winter and fix it for the snow season.

Torque Converter Clutch Circuit Performance or Stuck off

I would test it first, OHM meter

The Code comes up when engine RPMs don't match trans input shaft RPMs after computer activates then TCC solenoid
TCC locks crank and input shaft together via the torque converter for direct drive and best MPG

Torque Converters also have a "stall speed", an RPM where they lock crank and input shaft together
Google: testing stall speed
Easy to test

All the solenoids operate valves inside the valve body, valves are rods with o-rings and seals that when moved channel ATF under pressure to passages in the valve body to operate clutches and bands and, of course, lock the torque converter
Valves are spring loaded, when a solenoid is activated it pushes against the spring that was holding the rod/valve "closed", solenoid causes it to move against spring pressure to "open" it
But open and closed is not what happens per se, its more like ATF flow thru valve body changes pathways

So TCC Solenoid could be fine, rod is not moving or seals are leaking or wire to solenoid is intermittent
Or it could be the TCC solenoid, lol

Generally 20-60 ohms is OK

Ya we are doing the TCC solenoid here soon. We are also going to take it for a drive while it’s hooked up to a scanner and see exactly when and if which gear is slipping. Right now I have a ton of projects going on so this one hits the back burner lol
