Hmm i'm actually having the same problems man but mine is pulling like 4 other codes. Well from what i've seen if solenoid b was stuck open it woulldng give you second either am I correct on that? If it is sol b problem you can get one from napa for $17 and it only cost a fluid change, it's really easy to change one.

Have you been tuned for the stall. Thats A common code set with a high stall converter but its a false code because the pcm is confused by the converter slip

Idk if it's been tuned for it or not. I'm assuming yes because it has been dyno tuned. I just bought the car so I'm not sure. How do I remove it from limp mode, and what causes it to go into limp mode??

Mine just went too! It's been freezing here! My tranny was rebuilt 16k and they're not charging me to repair it. I have a stall converter but it never gave this code before, and I dyno-tuned it with the stock converter. They can diagnose it easily at a tranny shop, and just drop the pan to get to it. The tranny shop and my tuner said there wouldn't be a problem with the stall, but...?

Extreme temps, (hot or cold), will usually find weak parts in a trans, such as your B solenoid. Personally, I would buy a GM solenoid as they are about as inexpensive and much better quaility.

Ok replaced the ecm and no change got anything else I can check, i'm exhausted. Solenoids seem good, wirings from trans to ecm seems good, wiring from trans to fuse block seems good, ecm is good. So what else is there in this system that can cause this I can check?

If you can clear the code or turn off and restart the car and the trans shifts normal I would say its just the PCM being confused by the stall. IMO with any stall above 2600 the code PO757 should be disabled in tuning as this is a common issue

Your A Solenoid is good? If it was bad you would have no 1rst or 4th. The ECM should be fine. Does your scanner have a manual control to individually check the solenoids? You can also used a DVOM and check for high resistance on the A solenoid circuit.

Existing codes would do that. Glad it's fixed.
