Randeez 2012 Budget Yukon Denali Build (stick on hood scoops galore)

I'm confident you can change that yourself

to change that i mostly just need to pull the pump right?

was prob just going to have them swap all the clutches also while its out and apart

Never been in an 80 but I'd imagine so. You can swap the frictions and steels out while you're in there. Just check tolerance and get it on the lower side and you'll be fine. You may have to buy a spring compressor to get some parts out. I'm really not sure

I'll try to read up a bit after we do the 4th celebrations. I'm sure there's a million videos just like the 60

I'm just lightening the mood here....

You HAD a 6L80
You swapped to a built 4L80 and broke it

Maybe it's time to try a 6L90 or an Allison, the old 8.1 had an Allison so maybe you could use one of those, lol

 

[randeez]

they use a different spline output so would need another transfer case. but no either way lol
was also a m300 billet input shaft, i beat on it for a while, whole buncha transbrake launches... i may have to start pulling timing on the shifts again if i want it to last for more than a year it looks like tho

 

[mikeyss]

You have the NP149, right?

 

[randeez]

with a 32 spline input, yea

 

[mikeyss]

I wonder if you have too much traction, the vicious clutch combined with tons of power and the heavy weight of your Denali... It could be a recipe for destruction of any transmission you use. I hope you keep going with this project

Watched a quick tear down video. They took valve body and all that off, prior to pulling the pump. Once the pump is out, the input shaft comes out. Looked pretty straight forward and they used zero specialty tools during that particular tear down. Those are vastly different from a 60. Much heavier duty assemblies.
