Leaking A833

there isn't a seal between the bell housing and gear box are you sure it isn't the engine rear main that is leaking and just exiting there? or the front trans input shaft bearing, that's not hard, just remove the trans and four bolts holding the carrier on then change the seal
Hi, no its not the rear main, its definitely gearbox oil, i know there's no seal between bellhousing and gearbox but pretty sure its the front bearing seal.
Is it just a case of removing the 4 bolts for the carrier and replacing the seal?
