Looking to do GV overdrive on my 05 GTO, want to ditch the factory TCM. And have one controller control it all, and looking for better 1/4 times.

Is this possible?? do you have a harness available for 4L65E with a separate TCM on LS2's .

thanks again
CT Very Happy

CT,
Sorry for the delay in responding. With our controller you can control the GV unit and the transmission as one. It would require some tuning on your end to match the GV's shift time with the 4l65's shift time.
Our harnesses are for the transmission only. We don't do vehicle specific harnesses. You would be required to locate and connect Power, Ground, Throttle Position, RPM, Brake Light, GV solenoid, and buttons or switches for any of the special modes you would like to use.

thanks and cool avatar.

So you support 4l65e since it is not listed. Just want to make sure cause these have seperate TCM, is the wiring warness different???

tuning is no problem. I plan doing a 6 speed config. read few other post about this, sound like the 6 speed easiest and works the best.

We support the 4L60E & 4L65E & 4L70E which are all in the same family. There is no wiring distinction between the 4L60E and 4L65E. The 4L70E adds a turbine speed sensor and we added this to our harnesses about 2 months ago.

We also support the 4L80E & 4L85E. We sell just one harness for the 4L series which handles the 4L60E/4L65E/4L70E/4L80E/4L85E transmissions.
