Hummer 4l80e and 1995 k3500

[Cmstillwell67]

Hey everyone I am needing some help with transmission info! I purchased a 1995 k3500 Silverado that is missing the transmission and transfer case. I've been watching Craigslist for a 4l80e and found one with a transfer case (np242) for 75 bucks! He said it came out of a hummer that had a 6.5 diesel with 3k miles on it. Picked it up this morning and the label on it said 5kyp and it did not have a bolt hole at the 12 o'clock position so I assumed it was from a 1995. After I got home I realized the cooler lines are far apart and that happened in 1997 correct? So the only think I can figure is that it's a 2005? There is no neutral safety switch but I can mount one. From what I can tell all 4l80e's in hummers are the same. And the plug on it looks like the one on my truck. Can anyone help me out on anything I should watch for when I try to install this?

. This is the only difference in the plug for this transmission and the plug on my truck, the 2 wires at the bottom of the pic and they are labeld t and u

You have 97+ cooler lines and no 12 o'clock bolt hole. So unless the Hummer was special, this trans can't be any newer than 99.

Wouldn't that indicate it's an 05? I'm so confused with this thing lol

Going out on a limb here but it may be possible the military Humvee parts were made to a specific standard and not allowed to change over the years, to ease serviceability in the field and cut down on replacement parts inventory. Again, really stretching here as I have no direct knowledge, just a guess.

That is what I'm thinking also. I need to find the brackets to mount my shifter cable and I'm not sure what linkage I need for the transfer case. But I was really wanting to know about the wiring. I don't know what the 2 extra wires are for or if I need them

Also I don't have a clue what torque converter I should get. My k3500 has the 5.7
