It would help just a little to know what you are putting in front of this trans. The GM PCM does a pretty good job of controlling the trans, assuming you are using the LS platform.....
I ran/run an OptiShift (I think it is now US Shift) with a Cable X speedometer conversion on my 4L80E in my '63 truck. You can go a full manual valve body and forego the TCM.Been debating on trans, Was thinking 700r4 for the simplicity of it. But really would like to run a 4l80e. I was wondering what is the easiest to use as far as controllers ( simply shift,comp shift,tci...... looking for real world experenice. Thanks
