BMW E3. 6 3 Series Shift Bushings Replacement 1.Every BMW I have owned has always shifted pretty well providing that the shift bushings are not worn out.Very often on older BMWs, the shifting ability deteriorates as the years go by.While many people blame their transmissions and prepare for a full rebuild, their worries may be needless.In many cases, the shift bushings have simply worn out and need to be replaced.Worn bushings can result in sloppy shifting, misplaced shifts, and grinding when engaging gears.Most people are amazed at the improvement that occurs when they replace their bushings.A mere 4. 5 spent on new bushings is a heck of a lot cheaper than a 1.The first step is to jack up the car and gain access to the under carriage Figure 1.The main shift linkage components are located above the driveshaft.BMW Technical Articles Welcome to our BMW technical article directory.Weve gathered a vast collection of useful articles to help.About this Wiki.
