Default NTC 4l80e transbrake throwing a p0758 code
Friday I finally wired up my trans brake on my north Texas converter built 4l80e.. I was told to ground the B wire to activate the trans brake. It works good but now it threw a p0758 code which is the b solenoid ... My question do I need to delete the code out with my hptuners and just carry on with my business or what do I need to do?

It only throws the code when I get up on the trans brake button.. it doesn't go in limp mode or anything, it just throws the code..

Ok so I took it for a test hit in Mexico and when I get up on transbrake and launch it it goes to limp mode and stays in 2nd.. I guess I will just wait till 2moro and call north Texas converter and see what they say

Was your p0758 code reading the 2-3 shift solenoid or just shift solenoid? I did the same to mine earlier by setting the code to no error and it didn't fix it. Shows a 2-3 noid as bad on code but I can manually command it in the VCM controls and hear it clicking. The 1-2 doesn't click though?? Car is still hanging in first gear.

Not trying to steal your thread but wer were having same issues.

Ya, B is the 2-3 solenoid to my understanding.
