These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

7 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

hi, im currently changing the gearbox oil on my 1999 C4, so far it has taken 2.8l and nothing has came out the fill hole yet, Car is sitting level. Should I keep filling or stop? 1999 C4 manual thanks

POST 2Original post

When I changed my gear oil on my C2 I filled on level ground until the oil strated coming out the fill hole. Don't remember the quantity though.

POST 3Original post

I used 2.7l and it was just below the bottom of the hole with the gearbox out of the car and level.

POST 4 / ORIGINAL POSTEROriginal post

Hi guys, Put all 3l in and still no sign of it, All back together and seems fine, smoother shift. I have heard various volumes but im thinking if t was slightly low on the rear it would take more therefore maybe slightly over filled. cheers

POST 5Original post

sounds like too much... are you positive you're using the right fill plug? Check diagram http://www.renntech.org/forums/tutor...-instructions/

POST 6Original post

Nominally 2.7ltrs, maybe if you just rebuilt it. Often starts to overflow the fill hole @~ 2.5ltrs.

POST 7Original post

isn't it like 3.5 liters when you include the dif volume? fill it til it come out.
