wow, you revived a post from 2006 !
If you already have the transmission removed, you do not need remove the pump from the case to replace the seal. even if you do suspect there is some debris that fell in there, I doubt you will find it. a hammer and long thin screw driver should do the trick getting the old seal out, you might be able to get a seal removal tool in there.
Also, be aware if you choose to remove the front pump, you will need to replace the front pump gasket, the large o-ring that goes around the bump body and the washers that go on the bolts that hold the front pump. It is also recommended you use the 2 alignment pins when re-installing the pump to the case. you can do it with out the pins, but it makes things more difficult. (been there, got several T-shirts...
)
If you choose to remove the pump, there are 2 threaded holes in the front pump, which are used in conjunction with threaded adapters and slide hammer(s)
once you get the seal changed and ready to install the front pump;
**Make sure you replace the front pump gasket and o-ring before you re-install the pump **
Lubricate the rubber o-ring with vaseline or transmission assembly lube
tighten the bolts in a criss-cross manner and torque to 18-23 Ftlbs

It must be the thrust washer, I'll look for a better picture of one and let you know.
When putting it in drive (especially cold) you did not have to put your foot on the brake. It still felt like neutral but would go when you gave it the gas. It did not seem to slip other than cold start. It up shifted well. I'm wondering if The wrong part was installed? Or could it be something from further in that broke?
EDIT: Could it have been protection for the Needle bearing that someone forgot to remove?
Thanks for your help.
