Some quick transmission questions...

[ridelikehell]

Hey all,
I've got a little workbook I've got to fill out for college and I'm stuck on a few of the questions I'm hoping someone can help me out!...
The teardown was based on a Saginaw 4 speed, but I think these questions are general enough that they should apply to any transmission...

1. What part of the synchronizer assembly directly actuates the blocker ring?

2. If the front seal is leaking and the transmission is installed, what powertrain component can be affected, and what symptom would it show?

3. What component prevents the shifting of two gears at the same time?

4. What are two possible reasons for a repetitive rear transmission oil seal leak?

5. What are 5 locations where transmission fluid may leak out?

6. If the second speed gear in the COUNTER shaft is damagaed, how can it be repaired?

7. What are two reasons why thrust washers are used in the countershaft, as opposed to having it press fit in the housing?

8. Why are the synchros splined to the mainshaft, and the speed gears are not?

Thanks so much everyone!
