I've never really had that big of a problem with getting spewed by tranny fluid!
My secret is a combination of a 40" pan and a 2'x2' drain pan.
First you loosen up all the pan bolts with the 40 underneath. Then remove both sides of bolts leaving just 1 in the front and three in the back.
The you cable tie up the 2x2 drain pan underneath so there is enough room to get your hand in from the back to get the front bolt and then you pull it.
Then let drain and remove the remainder of the bolts.
Then wait 1-2 hours and then come back to the project.

Glad you got it done now it's my turn!

It wasn't so much a "spew" of fluid... more of just a consistent dripping mess. I did the loosened bolts... drain a while... loosen more... drain more... and finally the 'tilted' pan with bolts on one side. Working from underneath there's just no way to prevent the fluid from running down your tools... to your arm(s)... etc. 99% made it in the drain pan... but that last 1% seems to spread itself around to tools, clothes, and anything else that's touched during the process. It's just one of those jobs where you just have to resolve to yourself that it's going to get messy... kinda like good BBQ.

Also, I failed to mention that Troyer's price is $300 + a $100 core (that isn't charged unless you fail to return the stock valve body within 30days). Because I've used Troyer in the past (eFans, underdrive pulleys) I was already sold and confident of both their product(s) and customer service.

88, I'm going to add your "technique" to the "how to" thread. It may keep at least a teaspoon full of fluid off your arm!

I know with past tranny work. That trying to do them on the floor isn't always the best.
I've learned that renting a two post hoist and a stall at a local shop keeps me a little cleaner along with my tools. My garage floor doesn't get as messy either. They are a PIA.
Why the mfgrs never put in a drain plug is beyond my comprehension. That drain plug would make it so much easier.

what are the key benefits of these kits..? can these kits be used in addition to the gryphon programmer? or are they intended to be used in place of?

I wonder what a tranny shop would charge for labour to install this .. any guesses? i would never attempt this myself

Bill and I have discussed this here:http://forum.gopowerhungry.com/calib...y-upgrade.html

What a tranny shop would charge to do this would all depend on:

If they are hourly>>1-2hours.
If they have a jobber rate.
How much they charge for the fluid. You should use new stuff.
