$995 in and out on a 4X4 plus hard parts like gears, bearings and electronics. Clutches, seals, and bands included.
Allstate Transmissions in Phoenix.

I pulled the tranny myself and brought it to the shop was quoted 800-$1000 for a full rebuild

Cost $1000 because my od drum was fried, bought a billet piston converter from Transtar for $275 us core, transgo hd2 reprogramming kit for $120 installed by tranny shop, new Hayden fluid cooler and new lines for about $100 and I also decided on new converter to flex plate bolts from arp for $22

they replaced my tranny for 2700.00 and that was with a rebuilt unit. Knowing what I know now, I should have just limped it into the USA and had it done there.

Good thread im there also. Starting to slip when shifted into gear when cold

I just did a Th400 for my nephew, which shares many parts and design with the 4Le80. Master kit was $200 and did not need any hard parts or converter.

 

[6.2 turbo]

I just got mine back together,did the internal dual feed,and added one more clutch and steel to the directs.

They're of similar origins...but with no disrespect intended, implying a TH400 and 4L80E are alike is kind of misleading. Just like a TH350 and the 700R4/4L60/4L60E series have their similarities, the OD transmissions are far more complex and expensive to build. Most shops can knock out a TH350 or TH400 build for a couple hundred bucks, but once you get into the OD transmissions, you're usually hovering around a minimum of a grand, regardless of whether it's the light duty 4L60 family or the heavy duty 4L80E.

Care to elaborate on some of that ? What's this about extra steels and clutches?

 

[6.2 turbo]

Stock is 5 clutches in the direct drum,and forward drum. They can hold 6 by removing the wave plate,and using different thickness steels. I have only 5 now with the turbo 400 direct drum. Some people machine the pistons,and top plate for more clutches also.
