Is there any difference between a 2.0l gearbox and an 1800 ? My twin-cab has a noisy gearbox/diff and I was given an 1800 one (well, he said that's what it was). I was going to send it off to get it checked out before installing it, and I thought I'd better see if they're the same. Are there any i.d. numbers ? Do they have the same ratios ?

Nitram,
The GB's are different. 1.8L has a lower ratio and different starter (different flywheel diameter).
The mounting is the same though.
To do a swap you will need to keep the flywheel/clutch etc with the GB.
From memory the 1.8L box has 4 ribs and the 2.0L has 5 ribs (across the GB under the output shafts.

1600/1700 has 3-ribs and is a 002 box

1800 has 5 ribs also 002

2000 has 6 ribs and is a 091.

091 has different bellhousing and starter. You can use the 002 by putting the 091 bellhousing and starter on it.

The gearing is also different

Thansk for the correction Wes.

This is a 6-rib (I use this with my V6)

It will have an 091 part number. With 205/75R15's it will do 3100rpm at 100kph.

This is a 5-rib (I did use this with my 1915)

It will have an 002 part number. With 205/75R15's it will do close to 3300rpm at 100kph.

This is a 3-rib

It will also have an 002 part number. With 205/75R15's it will do close to 3400rpm at 100kph.

Does the 2lt and 1.8lt gearbox use the same aftermarket kit to fit it into a beetle ?

Wes, hidden amongst your vast wealth of vw knowledge, do you happen to have g'box and diff ratios for a '90 2.1 wbx? I don't think the o'seas models were different to oz but am not positive.
thanx

2lt and 1.8lt use the same adaptor kits to fit into the cars.

Tony, no I am not 100% sure on the ratios. I only really know what i have read about the ratios.

Try Leon from Leons Motors in Salisbury. He knows his gearboxes. Same goes for Lawerance from German Autos.

thanks Wes:thumb
