I did a search on code p0753 and its the 1-2 shift solenoid valve performance. i'm also throwing a p0300 multiple engine missfire code. Im guessing that the engine missfire code is because of my 3600 stall. I'm heading to the dyno tomorrow to get a tune and that code was gonna get fixed, but now i'm not too sure what to do about the p0753. I got the codes deleted and it ran fine for a day. I pulled it out of the garage today and it was running like **** again. Do you think it's someting that can be fixed by a tune, since it drove fine after a day or is it the solenoid itself and i should cancel this dyno appt.? is it an easy fix?? Thanks!!

 

I can say that the PO300 is probably from the converter like you said. You probably just need a CASE relearn to clear that right up. Happend to me when I did my converter.

 

Have your tuner remove the test for code po753 and -P0756 AND PO757 the code is likely a false code caused by the stall

 

ok, great thanks! I have had the stall for over a year though. Does it sound right to finally start throwing it now? I really hope your right though. btw, i have had the lock and unlock problem with the stall since the install, too. Thanks for the input!

 

The lock unlock will be from the missfire code
