Default 69 Fluid recommendations

Hello all hope all is going well. A little background about myself. I bought my dream car a year ago as a present to myself for getting my degree. Overall it's in great shape with lots of small details that need to be restored. It's a project with my dad who used to work on motorcycles.

Im planning to do an oil change and fill up the transmission & rear end. What are the fluid recommendations?

The rear end is stock but the transmission is a 5 speed.

​​​​​The engine is a 383 stroker.
if more information is needed I can double check my documents when I'm home.

The differential fluid in a 69 should be changed, you'll need a oil sucker. 85w140 gear oil plus the additive posi lube. My Tremec 5-speed takes ATF. T

If a TKO-600 Tremec, I use the Pennzoil Synchromesh fluid.

Can i use the same pump I used to put in the transmission fluid? I think there was a setting to reverse the flow on it?
