W56 B Trans Rebuild detailed w/ pics
Ok, I will do my best to show this rebuild in great detail so other members can benefit. I could of used something like this when I redid the last 2. There are two helpful ones on here but neither is totally complete. Thanks Photo Bucket. I will also show the tools I used to get this done. I am following the FSM step by step for the most part. I am sure there are other ways to get this done but this way has worked for me. Please feel free to comment or ask any questions. The 2 bearing separators are OTC 1122, and 1123. The big bearing puller is a posi-lock TJ-1. The one puller I do not have is my small 3 jaw posi-lock, its at work. The snap ring pliers are from The Snap On truck at work. I am not a brand snob but these are heavy duty and make the rebuild easier. Some of the snap rings in the trans are pretty beefy and my regular pliers didn't quite cut it. These are the only real specialty tools I used. Plus the one I had to make

Remove the bolts from the transfer case adapter to transmission. I use a stiff putty knife and a small pry bar to get the t/c adapter moving

Now this is where you are getting to remove the transmission case. Using a rubber mallet tap the corners of the case. once you get it moving I hold down on the output shaft and work the case off

Now the you have the cases off i clamp it a vise as the FSM suggests but i don't put bolts thru the bottom, I clamp it in between 2 pieces of 3/4" plywood

Now that I have it this far torn down I think I know why it was popping out of gear, the main bearing is toast there is a ton of movement it in. I didn't see any metal when draining oil. this trans only has 120,000 original miles.

This is the way the FSM shows removing these small snap rings. notice the magnet on the bottom, it helps not to lose the ring when you pop it off
