Step 1: Drain all fluid plug all holes and pressure wash with engine gunk so you don't get the parts dirty.
Step 2: While the transmission is drying clean your work area and lay some shop towels or something down so you have a good place to set down the parts as you pull them.
Step 3: Remove the governor using a flat head screw driver and hammer on the lip of the cover just like you would remove front hub bearing covers

Step 4: Remove the snap ring holding the 2-4 servo using a small flat head screw driver and hammer in one of the slots and then get a pair of channel lock pliers and carefully wiggle the servo till you can see the O-ring then use a small dentist pick or something small with a good point so you can pull the o-ring up then wiggle the servo till it comes out.

Step 5: Remove trans pan and filter then remove the wires from the solenoids on the valve body and put it off to the side.
Step 6: Remove shifter selector that's inside the transmission
Step 7: Loosen all the bolts that hold down the valve body till you can pull them up a little from there holes.
Step 8: make sure the transmission is completely flat with valve body facing up so that when you remove the valve body you don't lose any check balls.
Step 9: Remove separator plate from the transmission and take pics of where all the check balls are sitting so you have a reference on where to install them when you go to put it back together.

Thanks for reading all this mess as soon as i get the parts here ill show the rebuild stay tuned
But yes, they're good. I'll be duplicating those. I also have some good ones that are broke down in sections. Like the Planets, then the drums, then the pump, then the vavle body. They are just bigger and a bit more detail than most. Now these are good detail though. I'd love to have posters of those. I do hope soon to be building transmission like a sumbish, getting me a deal with a shipper, make a jig for crates, and I'm thinking seriously about doing nothing but Th350, Th400 and 700r4 Transmissions. I"d love to do 4L60-E's too, but being they are computer controlled, a computer issue can make me look bad or someone trash a trans then expect me to warranty it. I have ideas, but someday. I'll have to do something to supplement my disability.
