dry 904

Sitting for just 2 yrs. shouldn't be a problem for the seals. I rebuilt one for a friend and he didn't get around to using it for 3 yrs. but had no problem with it. Have you looked at it good? Make sure it was sealed up so no dust got in it. As far as being set up for a manual valve body that's no big thing since it has no valve body. The only difference might be it has had the springs removed from the accumulator and a restrictor put in the front clutch port. Since you'll need a valve body for it anyway you can either buy a good manual VB or put in a regular one. It would be wise to install a TransGo shift kit in a stock one if you go stock VB. If you do that you don't have to worry about the restrictor because it's a part of the TransGo kit. As far as the accumulator springs, without them it will just shift harder.

You can also bench test the seals without even dissasembling the trans. by applying low pressure (30 lbs.) air to the ports that activate the servo's and clutch packs. I can't ever seem to get photos to work here so if you want a pix of where to apply the air to test it PM me with your e-mail address and I'll send you a picture.
