I'm new to the 4L80 swap, what are some options for locking the tcc in a 98 ?
I just bought this project and do not have the option of going over any details with the previous owner.
The 4L80 is out of a 99 Silverado and I know it has been gone through, but that's it. Currently it has a manual valve body and a ratchet shifter. The convertor is a Yank PY 3600 . drives great, but I need to be able to lock the convertor.
Thanks for reading and any light that can be shed on this will be greatly appreciated.

So what is a Ross lock shift box?
What does it look like and where does it normally mount?
( in car ? Under hood? Under car? )
This car is supposed to have one of those on it already.
Any help is greatly appreciated.

 

I would definitely not lock a single disk converter under wot. Our multi disk in the 245mm diameter would be really good for your setup and able to lock up under power.

Thank you Brian,
I am looking to lock the convertor for normal driving.
I believed I have found the Ross lock box " little black box" and have it figured out. Gonna go for a test drive after work. Seem to be missing a switch for the ground side is all that's needed.
