6L80 to 10L90 swap? Seeking insight on a 10 speed transmission upgrade

[fozzi58]

Upgrade your the factory torque converter on the 10 speed. You don't even need to change the factory stall speed...just get a better one. Circle D, Yank, TCI, etc.

Been thinking about this myself. But I was also thinking a built 6L80 and a Gear Vendors splitter would set me back about $8k and I'd have a 12 speed and I don't have to replace my Circle D torque converter.

I ordered the 10 speed swap kit from Powertrain Swap Solutions yesterday!! Now working with Powertrain Swap Solutions to find a donor 10 speed and determine which shop will do the swap. EXCITE!

oh wow! Has this been done before? 12 speed is pretty awesome! How do you control that? Is it as simple as a tune? Or does the Gear Vendors splitter have a control module?

so besides the actual 10 speed transmission, the TCM, transmission control module?
what about any tuning for this 10 speed?

Not sure. I still have research to do but I will def post if I move forward.

Yep, tune is needed as part of the swap. Powertrain Swap Solutions and their certified partners include the tune as part of the turnkey swap.

10l90 swap into a l83 w/6l80e?

Negotiation with the East Coast shop fell through. I am now on the schedule for my 10 speed swap at Powertrain Swap Solutions headquarters in Nederland, TX on August 12! Road trip it is!

So obviously the 10 speed TCM is different than the one for 6 speed.
Transmission harness also different.?
So why would you need to tune TCM if it's from +2018 Tahoe?
The engine still a 5.3.

I'm interested in the total cost of this when you get it done.
