I will be using all new channel plate gaskets, separator plate and gaskets, and OD clutch kit.

The Transgo kit also includes different 4th accumulator springs and I use the larger of the two supplied and use it with the stock springs-where they tell you to discard them.
So, in total, you have 3 springs, not 2 in the 4th accum?

Something I've noticed with the higher end shift kits...they have you put shims on top and bottom of the pistons (1-2, 2-3). Why is that?

See if I got this straight here....

-Good idea to replace pump shaft.
-drill oil feeds
-also sounds like TransGo kit is the way to go

I'd give anything to tighten up the clutches. Man! I just can't.

What about the valve body? There are so many different shift correction kit styles and materials. Anything I should replace there besides the boost valve? Hell, the car might see 8000 miles per year at the most. I've been putting about 11,000 on my DD, so 8000 is rather high still. As it sits now and not replacing anything, it should do fine for another 5 years or so. But, man, a lot of work went into just getting the side cover off. I'd hate to have to do it again that soon! haha!

Even though the 4th accum is groovy, you can still see the machining, would it be a good idea to scotch bright it anyway? I'm about to purchase this stuff. I'm getting anxious to driver her again and finish tuning.

I'm going to PM you a question too.
