How did your swap go? Drive shafts work fine? Are you using tapshift?

Yes and no. It requires a 58x motor and ecm to work.

Front and rear drives shafts fit perfect. Blues controller worked flawless and was easy to install. Great guy to deal with.
This convertor and Trans really woke up the truck and spools the turbo so much quicker.

X2 on how great TBMotorsports is to deal with.

Glad everything went together good! Are you using tapshift?

I am not using tap, but true blues controller has a wire for it.

Ahhhh alright. I was curious as to how you set yours up if you did have it.

Would you want to use it? I'm pretty sure I have figured out how to make it work using that single wire in True Blue's harness (or if you just run a si for wire to the trans if Doug your own harness) and the factory sift lever with the +/- buttons. You would have to flash the Vette tune into the trans, but that's no big deal if you're doing the swap because you most likely are going to be tuning it anyways.

I'm doing my swap next Friday and will be able to confirm this when its done. I'm pretty excited about all of it. Lol.

The TBMS harness has a wire for the tapshift straight to the trans. I need to ask them which controllers/switches work with it.

The only factory shifter compatible with the TBMS harness without modification are the corvette paddle shifters. Which obviously won't work in our truck without a lot of modification. The factory truck shifter with the +/- buttons will work but you have to do some modifying to accomplish it. Not anything hard or complex, but it will probably be tedious.
The shifter is like $50, and the resistors needed can be had for probably under a dollar if your local electronics store has them. If not take to the internet like I did and probably have to buy 100 of each one(also like I did) for $5ish bucks per 100pack. So an extra $15 on top of your $50 for the shifter and then a little time and patience and you're good to go. In theory anyways. Like I said, I'll confirm this once I get it done. Lol.

Once it's confirmed and working then I don't see the cost of making a factory replacement chip that will just drop in being too high! I'll talk to TBMS about it and see what he thinks. I have no idea how to produce anything. Just tinker with it. Lol.
