Prepare your body...

Before closing up the transmission, we must first assemble the main hydraulics. A few changes are being made to this valve body, and if you’ve ever wondered just what exactly a “shift kit” consists of, you’re about to find out.

No gaskets, apparently. I thought that was a little strange, but I kinda like not having to scrape gasket material from all those worm-tracks.

We’ll resume assembly of the valve body in the next post. 41TE Assembly, Pt. VIII

LOL

This is, without a doubt, the scariest part of the whole job. WAY too many parts to remember where they all go. I took lots of pictures, but laying everything out in order and not disturbing them until I was ready to reassemble works great, too.

Those check balls add a whole ’nother level to this. Most of the transmission can be carefully taken apart and put back together just the way you found it. But if you unbolt the valve body and flip it over, those check balls can fall out before you get a chance to see which holes they came out of.

I’m afraid to ask how the shift kit works.. ...seems more complicated then my short throw shifter.

TBH, I didn’t take the time to understand each hydraulic circuit. These mods were all done on faith that they would make it shift... “better”. Whatever that means.

I think the springs might be for dampening the shifts. Sometimes you take them out, sometimes you replace them with different ones (identified by color). I believe this firms up the shifts.

Enlarging some of the feed holes allows accumulators to fill up with fluid faster. This was particularly noticeable on my Thunderbird’s 4R70W, where a hole for the reverse servo was drilled a little bigger, which nearly eliminated the one-second delay between shifting into Reverse and feeling it engage.
