Man, I don't have too mant tips to pass on to ya. Like you said, there are only a few that I have read here and they are so spread out through different threads. I really need to research a great deal more on here and dig all that stuff our and add it to my site. I guess the most important one would be to make sure you not only replace all your gaskets, but install them correctly. If you put the solenoid block gaskets on wrong, well... it wont work very well.

Either way, I can point you to a location that has decent rebuilt valve bodies at a good price. Check it out
here.
Keep me updated on your progress and I will add your stuff to my site, with your permission of course. I would really like to add BT's stuff as well, just haven't gotten around to it.
