P0841 transmission problems

[Pochek1]

Ok guys ive got a 07.5 3550 with 325500k and a 68rfe. A week ago i got the p0750 code for the shift solenoid. I did all the resistance testing and volt testing and determined it was the solenoid pack. So i changed the solenoid pack, fluid, and filters. That code never came back but a low voltage code came up after that.... i checked all the wires from the pcm to the tipm. Thought it was a relay in the tipm ao i by passed the tipm relay with my own relay... low voltage code went away but now i had a high voltage code !!! Soooo i put everything back to factory like it was before i by passed the solenoid.. no more high voltage code ... drove it for a day the i get a p0841 code !!!! Thought maybe the filter came loose so i dropped the pan again. My stupid mistake ..i left the old filter neck seal in. So i think i got it now by putting 1 good seal in .... drove it a 15 miles ... its back It doesnt come on after its cleared at any certain time. R N D it doesnt matter. It just randomly comes on. Sometimes i have to clear it with my mini maxx tuner other times i can just put it in park shut the truck off. Turn it back on and its fine .. i dont know what to do ... P.C.M. ??? Wireing? Im lost

Did you install an OEM solenoid or something else?

It was a remanufactured one

I was asking because all started with that "new" solenoid.
So in my opinion he is the problem here.

If you still have the old one, put that back in and see if it turns back the 0750 code then.
It would tell you if the new one is the problem ornot.

I shouldve said remanufactured solenoid pack. I am picking another one up tomorrow
