Default P0741 code? Help please!

I have this code listed in my Predator under DTCs not ran. What would be causing this? I had this crap come up when I smoked my trans months ago.
I have not been abusing it lately but did swap to 44lb injectors and my PCM last Saturday.
Any help on this would be great!!
Thanks.
Tim

Code lists as: P0741 (TCC Circuit Performance or Stuck Off)

dtc not ran scc (since code cleared)
shows what dtc tests where not performed during the dtc check
means the pcm has not run a performance test during driving cycle since code was last cleared

not a current code don't worry about it inless it shows in all dtc

Thanks for the reply.
I was starting to worry for no reason I guess.
So what your saying is all the codes in the not ran section of DTCs really don't mean anything until they end up in the other DTC section of the diagnostics?
The PCM must go through an entire cycle of these not ran every time I clear all the DTC codes out?
The only permanent one in there is the crank relearn which I know is there every time I swap PCM out and has to be cleared through the relearn procedure.

yup,
every time you clear the codes you will get a bunch in the not ran because these codes need certain conditions (certain speed, engine temp, throttle position, load, ect.) for the diagnostic test to be run, when the conditions are met and the test is run the code will be removed from the not run section.

the only ones you need to worry about are the ones in all dtc, those codes are there because the conditions where met the diagnostic test was run and the system being tested failed to meet the test perameters.

Default re po0741

hello- craig here- po 0741 will give you a very general "transmission component slipping code"- when run with a snap on or similar scanner- if trans seems to hold fine in all gears then you most likely have a slipping converter clutch- to verify without scanner- drive at steady pace- 50 mph- for about 30 sec. then increase throttle about 25% and watch tach- should hold rock steady- if rpms slip up= converter clutch is slipping- install transgo shift kit- even jr. kit addresses this problem- still slips some- conv clutch shot- better install all new bushings in trans also- as lube circuit is conv return oil and has probably been helping to lower conv clutch apply pressure. I rebuild these units every day - ask me whatever you want - I will be happy to answer any ?'s you guys have. Craig

Its sensing a slip from the loose converter and then going into limp mode,you need to have Nelson turn this code off.
