Exclamation Engine and gearbox noise

Wonder if anyone can help please

Bought the car in November in which it is a 2005 Roadster with 73000 miles on the clock .

While I'm driving I get a sound from the engine and gear box which sounds like you have not engaged the gear correctly even though it driving OK . This happens while driving around in 1st , 2nd and 3rd gear and seems to be a grinding noise .

Also on a few occasions while at traffic lights the gear will jump out of first gear or even while driving out of second . When this occurs I get a load bang which scars the crap out of me and my passenger .

This has been in with the garage twice in which they can't find any issues with it at all .

While stationery the car also makes a knocking noise .

Would any one have any idea .

Default Re: Engine and gearbox noise

1st hear pop out is a common occurence on the nsg370, mine scared the crap out of me when it 1st did it, 120k miles ago.

It is learning how to pay attention and driving this trans.
If you pay attention closely you can feel a double click going into 1st gear, if it doesn't, it is not all the way in.

If in question if it is all the way in, while stopped, shift to 2nd then back to 1st or 3rd, 2nd then 1st.

When coming to a stop, before car is all the way stopped slide into 1st.

Several other things can do or watch out for.

I have 178k miles on mine and original clutch, and mine 1st happened to me around 60k mikes.

I change the trans oil with royal purple every 50k miles
