A4LD DIARY - PT 2 (W/PIX ALSO)
This is a continuation of a thread on the attempt to build a "near Bulletproof A4LD". Part one can be accessed here:

This is the continuation of that thread - in part 1 we tore the transmission down to it's base parts. In this thread we will evaluate and rebuild each component, and in part 3 we will reassemble the transmission.
We'll start at the back, with the governor assembly.
GOVERNOR
I promised I'd start this new thread of evaluation and component rebuilding with a look at the governor. For those of you with pre-'95 explorers, this can affect the 1-2 shift, and final OD shift point. There is a "wave" washer at the back of the case which apparently has a bad reputation for contaminating this governor valve - but the good news is that you can get to the governor with the transmission in the car. You can remove the transfer case and get to it through the extension housing (there is a pic looking at it through that housing the the first part of this thread), or better yet just remove the extension housing, it's not hard - and you are already going to be replacing a gasket on the one end, what's one more ?
Here is the governor in its parts - nothing holds it together so it easily comes apart. The part are the main body, the valve, the counterweight and spring. FYI a new one is $65.
There is an upgrade of a slightly heavier counterweight, lowering the OD shift point (or maybe putting it back where it ought to be). I plan to add this.
None of these part have been polished - yet. Here's the main body, showing the place the weight rides.. it's aluminum so I'll lightly polish it.
Here's the valve assembly... minor scoring, not bad, but it is steel so I'll buff it up..
And here is the old weight, which I plan to replace
To polish I am using 3M scotchbrite, in the "fine" category
I cut a piece and swirled the valve in it - (it took both hands but I needed one for the picture)... polished up nice... once you are done, clean it good (I use brake cleaner) lube it with either transmission fluid or vaseline (I lubed it with vaseline) and reassemble it to reuse - with the new weight, if you choose to follow my path.
That's all there is to it!
