Manual Transmission, Reverse Question
#22
Simply use your foot brake to stop the car before shifting into reverse. Unless you are on a very steep hill, a small amount of rolling is ok.
Comment: Absolutely constructive advise!!! This is educational input!!! - rttby

Since it was already in my photobucket, I figured I'd upload this picture just for fun. This is the inside of a GD3 manual transmission. The lone straight toothed gear on the bottom front of the picture is the reverse idler gear. On top of that gear is a little metal "finger" and there is another finger underneath the gear also so it is like a fork.
When shifting in reverse, the fork pushes the whole gear cog down so that it connects with the other straight toothed gear located on the gear shaft on the right (the countershaft) and the shaft on the left (mainshaft or inputshaft). Since these gears are straight toothed, if you are unlucky, the teeth might not line up well so shifting into reverse can occasionally be slightly difficult. Remember that the countershaft is always connected with the wheels (via the final driven gear, located on the bottom right of the pic with a number 8 stamped on it) and will be spinning whenever the wheels are spinning, even in neutral.
***note*** the GK is a six speed so the gear layout will be slightly different but the reverse gear is the same.

This is awesome, thanks for sharing! So why are the other gears angled but not reverse?

The gear type is called "helical" and it offers a more gradual/smooth connection so it produces less noise than straight or saw toothed gears and is common in high speed situations for noise abatement. When lower speeds are envolved a saw tooth gear is used like in the case of this transmission. Apparently some older cars (like certain Lotus') used straight toothed gears even for forward gears so the car would produce the same whine we hear in reverse when going forward! Must have been a noisy ride!

Here's a view from the back. On the left there is the shift fork/collar for 1st and second, in the middle is 3rd and 4th and on the right it is fifth and reverse. You can see a little "finger" on the bottom of the right fork which pushes on the little fork mechanism (lower right) to engage the reverse gear. If you look carefully at the bottom of the mainshaft, you can see a very small straight toothed gear. That's the one that is used in reverse I believe. It is obviously small because you don't want to reverse at high RPMs! At least I don't want to. Maybe it's a mod for someone
You also have a better view of the differential on the complete left. The hole is for one of the axles.

Very happy to be a long time Honda fan.
