Po757 after a stall converter and how to remove it in hp tuners Removing the test for PO757 with HP TUNERS
This code should always be removed IMO during tuning with any stall over 2800 rpm.
This information provided to me by WHEATLEY a tuner/sponsor on the truck forum.
(Wheatley)“Set the PO757 code to no error reported. To do this, open the tune file. Now click Engine Diagnostics>DTC’s. Now scroll down the DTC list until you find PO757 uncheck the box next to it.
To the right you will see 0-MILL on the first error. Click the pull down arrow and select NO ERROR REPORTED.”(Wheatley)
It’s that simple. I would imagine it’s similar in other tuning software.
Doing this will eliminate limp mode second gear only after a stall a very common issue with stall and IMO should be done anytime your tuning for a stall above 2800 rpm.

I was with the person that tunes my car today to try this on my car because of the problems with the PO722 and PO757 codes. The PO757 code wasn't listed and the PO722 code was already set to report no error but still got the code? Any ideas why it would still throw a code?

Unfortunatley while the code is indeed there its not in the PCM but the TCM on the 05-06 gto which have a unique controller. What I am hearing is that HP TUNERS cannot get in the TCM but I am told EFILIVE can. Someone correct me if I am wrong.
