I've noticed recently that more often than not, the gearbox in the Panda will crunch/grind when engaging reverse. It seems to be completely normal going up/down through the rest of the gears, though.

Now, am I right in assuming that there's no synchro on reverse and this is semi-normal, or is it time for a trip to the dealer?
 
If you rush the shift or try to do it with the revs up a bit, it'll crunch. I've found the same in a lot of cars I've owned.

Just shift with the engine at idle and take it easy, you should be fine. If it crunches under those conditions, it's time to see your dealer (if under warranty, a competent mechanic otherwise).
 
Good, that's what I was hoping.

Not sure if the TwinAir is the same, but the 1.2 seems to up the RPM slightly when the clutch is depressed at a standstill, more so when the A/C is on. That'd explain why I've been noticing the crunching more often lately (in the summer months).

you are correct, it's basically a REV's thing, (y)
you want to make sure the gearbox internals have stopped spinning, and get the engine down to idle.., :)

my Punto TA - 6 speed is actually perfect for reverse engagement:worship:

my '07 panda 5 speed FIRE crunches regualarly..:eek:

Could just be a tired clutch master or slave cylinder, a wonky clutch plate would show up from new, but probably to do with waiting a second or two before grabbing reverse.
 
I was bored lol nowt on tv so listening to liverpool losing again on the radio. Had folder on side opened to look and before i knew it id read most of it sad i know lol
 
Historically cars haven't had them fitted but a few do. No idea why unless there's sufficient latent drag in the gearbox to make it necessary. Heavier oil perhaps? Probably just accommodating ham fisted owner's ?
 
Could it be low Transmission fluid / oil? And do you know how to check the Transmission fluid level?
 
I forgot entirely about this thread! My new Panda does it occasionally as well, so I'm not that worried. "They're all like that, sir".

I've noticed it depends on a few factors though...
- How quickly you move the gear level from neutral to reverse
- How long you wait after depressing the clutch before engaging Reverse
- Engine RPM
 
I wonder why the engine RPM matters - but it does. And if the aircon is on the RPM is higher, so turn the air-con off.

I also make sure I alway drive just a cm. in first gear before going to reverse, never from any other gear and into reverse. Don't know if it makes a difference, but I have been told, that first resets the gears.
