I think this has been spoken about before , does anyone know the actuall cause of this problem and is there a fix? My dealer said they are going to try and change the oil .

Yes mate,

Oil change won't help a bit, the dealer is giving you the run around.

The problem is the brass they made the 5th gear synch ring out of is too soft and the crunching will only get worse.

I got it in the Silverhawk and had a new gearbox fitted at 8000km.

Fixed the problem OK and the replacement gearbox was better than the original.

If you go faster the crunch gets worse, mine would be OK below 100kph but the faster you went the crunching got worse.

See your dealer and demand a replacement gearbox. They have to get onto the manufacturer and they send a gearbox out and the dealer sends the old box back to them.

Hope this helps.

I don't seem to have a crunching problem with 5th gear.

Come to think of it, I don't seem to have a 5th gear

How to I enable fifth, this would be quite handy on the freeway... :banghead:

What if I solder a small animal to the ecu, will that help???

Thanks for the info , that's exactly what mine does . I have 9k on mine now and it started doing it a few weeks ago.

Oi folks,

First gearbox started crunching into top at 12000km (initially above 120kph, then progressively worse 'til every change was bad). Second gearbox lasted about 600km (it was a shocker - poor selector "feel", tight in all gears and crunched from the second day. Got about 9000km on the third box and all seems well, 'cept now my brakes are shuddering!!!!!!!

Ah well, all warranty stuff.

Ciao

Is this happening when you just shift from 4th into 5th normally???? bugger

if I go from any other gear 2nd or 3rd to 5th it usually grinds.

30,000klms on mine now

Works for me!!! :banghead:

Thanks I never thought of that .

Mine only does it when shifting up into 5th and more so when speed is over 100km.

Oi,

Bloke at the dealer said that Borg-Warner had mentioned that short-shifting (2nd to 5th or 3rd to 5th) had created some problems, and that it was not a good practice with these boxes - maybe because of the softer brass synchro ring??

The "common fault" develops initially with crunching on high-speed 4th to 5th changes, and then progresses to every use of 5th.

Once you notice a few dicky changes. you gonna get a free gearbox! I got three with mine so far! Now that's a bargain.
