Tunerpro transmission parameters

Post by Sachem »

In the transmission parameter section, it allows you to set a 4L80E trans to manual shift via pin 71 and pin 31, but doesn't give any other Information. Does anyone know how to do that or know where I can find out how? I want to be able to go from automatic shifting to full manual with downshift capabilities. I want to keep my OE pcm. Not looking to buy an aftermarket controller, spent too much time modifying my harness.
Thanks
Tom

Great information . It's good for full manual all the time. I want to be able to switch between manual and automatic through pin 31 or with a shifter that provides regular and sport shift (manual) modes. I appreciate the reply.
