Swapping out the tailshaft - 4L65E I've got a 2005 4L65E out of a Sierra 1500 and I want to use it in a 2WD application. I've trawled Youtube and seen several disassembly videos. I'm fairly sure that I need to remove the valve body so I can unhook the front band before I can get the drums out to reach the retaining cir-clip.
Can anyone confirm this as 100% necessary. And if I do have to remove the valve body, should I replace the paper gasket or hope they separate in one piece?
I have a 2WD tail-shaft and rear housing all ready.
Thanks - over in the UK so I would have to chase up the gasket :-(

Removing the valve body makes it easier to get the band out, but I would say not absolutely necessary. You do have to remove the servo for sure.
You may want to buy a "reseal" kit to be sure you have the servo o-rings, the VB gaskets and the gasket between the pump and the case that you absolutely must replace. There are o-rings on the 6 pump bolts that should be replaced too.
Opening a trans this far is a slippery slope - you are likely to tear the teflon rings on the stator shaft or the input drum. Before you know it, you are doing a complete rebuild.

OK, never simple, all points taken. Spotted this video today which shows it can be done.
at about 1:15. Does not show if the servo has been pulled though....
I have the pump gasket, sump gasket and now I know to be VERY careful.
Thanks :-)

No way around removing the Servo, Then you can lean the Input Drum/Reverse Input Drum away from the Band Anchor, Unhook the Band off the Anchor, Then pull The Input & Reverse Drums out.

Well that went well :-) Only had to release the servo a little (far enough to let the o-ring pop into the c-clip grove) to get the band off its peg, everything else went very well. Just got to swap it into the car and try it out. Only a 4L60E though, not a 4L65E as the www implied it might have been. All nice and clean inside, including the pan. Very little dark matter.....
