very good information...
you make it look easy. If I had all this info I wouldn't have gone with a 6 speed and 2wd when my 60E broke, honestly. Your lucky finding a cherry 4WD 80E for a grand. LS1truck 60E to 80E has some great info but yours is more detailed and organized, especially for the 4WD.

I'm done with the easier parts. Now the work comes. I'm a little bit worried about swapping the input shaft in the transfer case. Reminds me I need to get some good snap ring pliers.That little bugger was a pain. Grind a little. Grind a little more.... hmmm thats to much grinding on that end. Lets grind the other end. Hope its right.

I'd highly doubt you'd need it...but I have to admit, I'd probably put a little mini cross brace on each side, little 90*'s. I know that flat metal is strong turned sideways, but man it just looks like a weak spot you know. Killer man...looking killer!

Was viewing your thread here and saw a couple things you might want to look at again. The hole drilled here looks small. If I remember correctly it should be a 3/16 hole. It looked small in the picture just thought I would point it out for you.

Here is your picture of the accumulator pistons when you took it apart. Notice where the yellow spring is. The longer of the two springs in a factory set up always on the accumulator piston not using the pin. I believe this is the 3rd accumulator.

Here is how you reinstalled it with the supplied 3rd accumulator spring from transgo. Notice where the yellow spring is. I do not think it is supposed to be used in this location and also is the wrong spring. I think you should double check this step.

Vince thanks so much!
Good catch.
I've looked at it again with the rest of my pictures and the trango instructions. I think the hole is the right size but you are right the 4th accum spring is wrong. I have to tear into it again to do the pump mod for the PI converter so I'll fix this.
I'm sure I'll look at it 2 or 3 more times but I think this is right tonight.

Not a problem. After 19 years of staring at this stuff I have learned a thing or two. Take a look at the hole I pointed out. I believe the directions call for a 3/16-.196 hole. It looks like you used a .120-1/8 bit. I normally start with one of the small bits supplied and work my way up to the largest one. Makes it a little easier to drill that hole on an angle and also helps you stay off the valve body gasket surface. Nice pic's by the way.

I will check the hole of course. If that one is wrong so is the other one. I used the bits they provided but didn't measure them. Did start with a smaller bit then stepped up. Also punched it. It was hard to do that hole and stay off the VB seal surface.
