Go-shift 4l80e

 

Got Go-Shift and could any one help me how to lock up tcc on 3gear, 4 is locking as it should.

Speed and rpm is on range but no lock up, shif OD position, does this affect?

Transmission is 4L80E.

Then second question,

4L80E transmission, it has Trans Go:n HD2 shift kit and build to manage 800hp/1000nm

What kind of line pressures are you using or could recommend?

I hear that i will burn up tranny if not using correct preasures.
