Tranny swap question?

[aquapool]

Finally got a new tranny. Never taken one out before. Its a 1990 535ia Prod. date 08/89. Wondering if ya'll could recommend all the parts and gaskets I should get before I start pulling things apart. Or if you know a good link to an old thread. Thanks!
So far I'm ordering:

service filter kit
Redline fluid (Heard this is the best?)
trans. mounts

[632 Regal]

all I can think of is the reverse torx bolts that hold the trans to the engine, other than that its straight forward
