    How to Tap Up/Tap Down (TUTD) (Tapshift) with 6-speed/NO BCM/NOT Corvette Tune

    6 Speed Auto TUTD without BCM and without Corvette tune.
    This is a Microsoft Word document with very easy and clear instructions for you to enable the Tap-up/Tap-down (TUTD) function on a 6L80e or 6L90e trans, without a BCM and without using a "Corvette tune". You'll definitely have to buy parts and know how to solder, but it ain't rocket surgery. I ain't guaranteeing it works for you but it should if you pay attention and do as you're told...lol Seriously; give it a look and let me know.

    So i have had my TUTD working for a couple years ago, i was a partial contributor to this post, but after deciding id like a cleaner switch than my home brew option, and wanting cruise control that my oem gm stalk would control. i found OEcontrols tap'n'cruise BMC. super easy to install and very nice guys to work with, unit works perfect with GM oem TUTD shifter. wires to my 89k5 crurise control stalk for perfect control, its got stuff for ac control if you didnt already add it to your harness, and they added a high idle input for my for my OBA setup. if you are thinking of going cruise control, this is a cleaner solution than other aftermarket offerings. and not much more money.
