No experience but you sir are living the dream. Saw your rig on I-81 in Virginia going south for Expo East (crap trip for you if I remember correctly). Bad ass stance and well put together rig.

I have some experience with these and have seen one in action but not on an 80.

At all?? Then why do they claim they have it, or is it for pre 95
What it will work on is an A440 which is the earliest trans that came in the 91-92 80 series. I have seen one installed at the shop I work at onto an H55 and then mated to a split case and it was going into a 74 series. Another one that I have some experience with is the on in my dad's 60 but again an H55 and a split case. Im pretty sure Torfab has mated one in a 62 to an 80 case but I forget which trans, definitely not the a343.

The other thing to note about the black box is that for street applications you need to increase the fluid capacity by a few quarts by adding a reservoir, pump, and a cooler other wise you will melt the internals and damage the box. They don't list that information anywhere on their site and that information was gathered after calling them directly

Ding Ding Ding! This is what my buddy found out from them after burning one up.

I will say they are strong. In my dad's 60 he drove 1000 miles from SF to Denver and then 1000 miles back on his black box for my wedding. He and Georg also discovered the fluid capacity problem after that.

Here is a link to Tors Facebook post. 6l80e black box and the 80 case


Other thing to note on an 80 is the gas tank has to be modified or moved

Wow! That should definitely be disclosed up front and on the website!

I have given serious thought to using one as adapter for LS+6L80 swap. If it’s not suitable for prolonged highway use, that makes it a nonstarter.

It literally requires extensive modifications to the floor and other parts of the vehicle in order to work and it’s pretty expensive to boot. But you’re concerned about adding small pieces like that?

It is suited to highway driving but it needs extra capacity to make it run cooler. As it is there is only about 1/2 quart of gear oil and there really needs about 3-4 quarts to keep it cool. Like I said in an earlier post my dad's black box made it over 2000 highway miles in just a few days on the 1/2 quart and it didn't grenade, it got hot but didn't fail. With the extra fluid capacity added there shouldn't be a problem. Add a reservoir, pump, and a finned cooler and the highway problem is solved.
