For manuals, yes, Reverse does not have synchros, so the car has to be stopped before going into R. And even stopped, sometimes the gear teeth might clash.
But for Autos, there are no synchros.... They use planetary gears...

All I know is that when driving an auto you shouldnt be changing the gears while in motion as it can damage the gear box especially if your transmission oil isnt in great shape. Dunno bout explanation of why this happens cause I never bothered asking into details why this and that happens, just asked if its bad or not.
In general you should stop the car before reversing (if that's what we're referring to still atm).
But, i agree, even when stationary you will still get the painful grinding sound in a manual.
For those in a manual - I've noticed the last week or two that when trying to shift into reverse it only goes half in, and normally i shift into first and then back into reverse to get it to go in smoothly - can't explain why - i read somewhere about it that it works - and it does. But.. it seems to be happening, even when it should slide in nicely, it doesn't.
Could it be the recent cold weather lately? or a good service and change of fluids?
The "halfway going into reverse" for manuals happens because the reverse gear is a straight cut gear (with a slightly flat top), so there is a chance that tooth meets tooth and cannot go in. If it is warm, the transmission fluid is less viscous, and there is a chance that the gear will slide in if enough force is used. If cold, then it'll be stuck on the tooth. Just pull back to neutral, and try again (others recommend shifting into another gear so that the teeth shift before trying again).Quote:

im just glad to hear its not just my euro.
I've had that happen, but it rarely happens when shifting into reverse.Quote:

It's very frustrating to have that happen when you are trying to take off in a hurry.
i find it happens when i try to shift into 2nd from neutral rather than first most times. But agreed it is annoying esp when you are in a rush to get out of a jam
thanks for pointing this 'click' sound out, jl88rl. i never noticed it before, but now that youve mentioned it, i cannot help but notice it...
I have the same issue & I actually got the dealer to get a Honda technical person to come & listen to the noise. They have assured me in writting that it is a normal operational noise & will not effect the operation of the gearbox. Apparently it is a gear slidding along a shaft & only occurs when the gearbox is cold & the clearances are tighter.Quote:
