99 C43 transmission leak

Hi everybody!

New member here, ready to join the AMG family! Lived for years in Stuttgart, committing twice a day by the Unterturkheim MB headquarters. Now living in a middle of nowhere..well sort of, at least nowhere near a good MB shop.

I need a bit of advise. I am looking at a 99 C43 with 91k. The car looks good except for a transmission leak. The owner has replaced the transmission in 2008. He showed me paper work for the purchase of a gearbox-$1800 and installation-$400. The paper work doesn't state at what milage was the work done, or that it was a C43 gearbox. Owner also claims he can't recall what the milage was when the work was done. The current transmission is leaking a little but the fluid looks clean. Where I live there is no shop that can really tell me if the new transmission is genuine C43 part, or diagnose, fix the current problem.
I test drove the car and it seems to be shifting fine. I don't really know how it is suppose to be shifting, as I've only driven stick shift all my life...

Not having a shop nearby that can tell me what the problem is with the current transmission and if it is oem part, what would you guys advise me to do:

Purchase the car, or move on?


Thanks for your help!

Stamped on the gearbox just above the pan is the gearbox number. it's a long number but if you can let us know the first 6 digits (7226??) we can tell what the gearbox was designed to fit. Most people fit a E55 or CLK55 gearbox in the case of failure as they are a direct swap.

As for the leak its usually just the pan gasket or the electrical plug seals, both are simple and cheap fixes.

most leaks comes from a bad pilot bushing.
my tranny once leaked from a worn pilot bushing that's the only leak I ever had.
