Simply changing here and there does not solve the root of the problem. the problem is not all mechanics knows how to fix BMW problem since it incorporates various control unit here and there - these will justify how your component should work properly or not...FYI - any BMW cars with automatic transmission built from 1996 onwards is using lifetime ATF (automatic transmission fluid) - meaning no need to change the oil forever. You just need to keep the ATF level sufficient. If there any leaks in the gearbox, then it are necessary to renew the ATF up to specified level after leaks have been rectified. Only Ah Beng's workshops say you need to change the ATF as part of routine maintenance just like Toyota, Nissan and Proton cars. Once the ATF has been replaced using aftermarket ATF which does not correspond to BMW lifetime ATF specification - existing gearbox is a gone case!I believe yours is THM-R1 gearbox. There is one repair solution regarding adjusting the brake band if the jerking becomes an issue. This is a just temporary solution, meaning after adjusting the brake band the jerking cannot be resolved - new gearbox for sure... too bad jadinyee...</blockquote>
