8 or 10 speed automatic transmission

[TheRedditt2]

I have a 2001 Yukon Denali and I was looking to upgrade from the standard 4 speed to an 8 or 10 speed. Does anyone know if either will fit?

That would be the BOMB!
The big issue is having the computer to run it, the 2001 won't.

I would love that though
Gen2 Tahoe/Yukon with 6.2 LT1 and 10 speed trans.....I'd buy that in a heartbeat.
I wish GM would make a Connect and Cruise package in that combo that plugged in.

They make an LT1 combo with 8L90E combo that comes with stand-alone computers and mechanically should bolt right in.
but its a 2wd trans which could be converted but would also have host BCM issues......
Maybe some day......

GM makes an LS3 C&C 4wd package but it comes with a 4L70.....and not what you're looking for.

My 2019 Sub with 6.2/10Spd with 500hp gets 27/30mpg on the highway going 80mph......
I 've love that thing but I'm not going to spend $80K+ for a Tahoe with the same.

I asked my grandfather who’s been a mechanic for 45 years, he said that you’re right. But he also mentioned that you could do it if you replaced the transfer case, I’m not sure to what else you could change it to. Does anyone on here know,? Y’all seem to be a very knowledgeable community.
