    I did my own and only needed picks to get the snap rings out. Pump puller would be nice but not necessary. There are two holes in the pump that are threaded and you can stick some long bolts in those two holes with something on them like a slide hammer and the pump comes right out. Just have a really clean place to do it.

    Yep. You can unbolt it, turn the bellhousing towards the ground, and drop it on something, like your lawn. The pump will just dump out.

    I did a TH400 and Th350, only thing I would have liked to have had was the 1st/reverse clutch tool. Could have made one I guess, but for one or two times, I just took it to an auto trans shop and paid a technician $5 to do it for me.

    Guess I could have done the spring compressing with C clamps, but instead I used a shop press. Actually worked good, although had to get creative on how to mount stuff. /forums/images/graemlins/smile.gif

    I thought the 400 was easier than the 350, then again the 400 is what I "learned on". Amazingly enough, I saw one of the transmission rebuild videos (for a 200-4R) and after using the manuals for the other ones, the video was the hands down winner.

    Thanks /forums/images/graemlins/thumb.gif I thought as much. I remember a few years ago a friend of mine rebuilding them and I seem to remember him fighting a lot with some of those snap rings

    Yeah I did a TH350. So far so good. Still running fine 4.5 years later.

    I took a Harmonic ballancer puller, peice of 2 inch wide flat stock, 3 3/8 x 1.5 inche bolts with nuts and made it function as a compressor for the clutches. It even did the #1.
