Let's see if you mopar gear heads know what you claim you know!:booty:

Automatic Transmissions:

1.) What is the most common way to drive the hydraulic pump on an automatic transmission?

2.) What does a simple planetary gear consist of?

3.) In the neutral operation of an automatic transmission, what drives the input shaft?

4.) What type of gear has teeth at an angle to the gear's axis or rotation?

5.) What is meant by gear ratio?

6.) What type of gear ratio is direct drive?

7.) What is the function of the boost valve? (Hint: Hydraulic system).

3...2...1...go!:D

P.S. From my Air Force CDCs (study guide thingy). No worries, those are questions I already did, lol. More to come as I go along. I'll wait and bit and show the answers.:banana2:

I have no clue on any of them but I haven't had an auto in about 8 years. That's my excuse :jester:

I'll take a swing at it...

1 - No Idea...
2 - carrier, planetary gears, sun gear
3 - nothing? (guess)
4 - helical?
5 - input vs output rev/min
6 - 1:1
7 - No idea...

1 - The input shaft drives the pump...it's splined.

2 - Sun and planetaries.

3 - The converter drives the input shaft.

4 - Helical cut gears.

5 - The differentiation of speed from input to output.

6 - 1:1

7 - Boost valve?

What he said^^
7. The boost valve regulates the line pressure which in turn provides the clamping force on the clutches and bands.....bigger boost valve =higher line pressure=fimer, later shifts......
