Hi there, thanks for your reply. Hopefully I drained and refilled the box correctly following the advice I found on this site as well as guidence from a friend of mine who is a senior technician for Citroen. He got me the fluid from a local VW garage so I hope it is ok. One thing I am still not sure of is where the level plug is for this gearbox so I can't be sure the fluid level is correct. There is a 24mm drain plug bolt and a plug in cap for filling. I seem to remember the code for the box is someting like jc j07 or something like that. Any ideas? Thanks again
