transmission rebuild questions

[blueranger]

I am going ot rebuild my transmission DIY..
1983 300sd. I have been studying the manual and
I have a few questions...

1. what would you use to hold the ball bearing valves and other
small parts in place...? (vaseline)

2. What would you use to hold paper gaskets in place?

3. What would you replace? (i plan on replacing bands and clutches)

4. The manual calls for rebuilding the b1 and b2... but I think I should just
replace these... what do you think...

5. I guess I should also replace the modulator... should i replace anything else.?

6. If I replace the clutches, and the bands and the b1/b2 should I worry about the break band measurements... since its all new?

7. The manual says reuse the torque converter... what do you think...

8. How would you clean the exterior and then interior.... how would you clean the valve body....
