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

 

Bump.

 

Just got off phone with north Texas converter... Need to set the code to no error reported and should be good to go..

 

Hey man, is that the code that throws the transmission into limp mode? I'm having issues with mine and it's throwing same code.

 

Yea it's one of the codes that will make it go in limp mode..

 

You just set it not to throw error in HPT?

 

Yea.. if it's not raining this eveing I will test it out on mine

 

in for updates

 

Ok so I put the p0758 code to no error reported and went and made a hit... Everything worked perfectly..

 

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.

 

This is what my code showed up as
P0758- Shift Solenoid B Circuit Electrical

 

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