What did you do to your NBS GMT800 Tahoe/Yukon Today?

[ArcticYukon]

Dang ok I ordered this product called rage from superior products yesterday. I am gonna try this stuff out and if it doesn't work then I will give this a go.

Oh and the black bolts should be here tomorrow but I am having no luck on the black washers at all. I went by Home Depot and they didn't and now I may have to just paint the washers myself I guess.
2004 Z71 Suburban Green I have a few upgrades done.

Found these if they'll help....

What’s done the trans? I need to start saving or find a core to build. I want to do hood rat stuff without a bunch of neutrals

The trans is a Performabuilt level 3 “ invincible” built for 900 HP that I somehow managed to grenade. They just rebuilt it under warranty.

I want to build the 4l60. I think it can handle a n/a 6.0 if the right parts are installed. Not sure if a 80e swap will be cheaper

Imo a 60e will last but it depends how you drive and how much you beat on it

Maybe you're pushing 901

A well built Transmission doesn't usually fail on it's own. Something outside the guts could have killed it.

It got too hot often.
Running low pressure.
Failed pump?
Torque Converter fail?

Issues as these, could have been a problem, and you may have not noticed in time.

If you drive aggressively or tow a lot, ALWAYS SMELL THE FLUID !!!!

Since I put the 3500 stall in, my trans temps are up 20 degrees. I have the factory tiny cooler outside the radiator. I don’t really beat on my truck but when I want it to go I want it to go. Lol.

Never got hot once. New trans, built for 900 hp, pressure was good. New 3 disc billet converter rated for 1200 HP, just opened up and checked by FTI. No issue there. May have been the pump, Im trying to find out from Performabuilt what exactly they replaced other that “it grenaded”. Whatever it was, it was pretty violent and happened under full converter lockup at WOT in an AWD launch with a blown and crammed 6.0 that I’ve never dyno’d. Damn trans locked up enough to kill the engine even after I shifted to neutral. It sure was fun though. Oh, and I drive REAL aggressively.

I used to live in Marin County ( across - North of Golden Gate Bridge)....

I used to see guys in trucks drive through "rain water"... not remembering it was flooded salt water.

Real smart.
