Changing Fluid, How much do I need?
The following threads may help you somewhat:
Royal Purple? Is it really worth it???
Where to put ATF in on a T56????
Is this ok for my t-56?
What fluid do you guys use in your T56?
Changing Trans and rearend oil?
I put the above thread in bold since it has a few links in it in regards to T-56 fluid - you might want to give a good read through the Blocker Ring thread, since you have a 98 T-56.
Good Luck!

Chuck
