Hi all hope everyone had a great new year!!! I have an annoying issue with my e38 735i She starts and runs perfect bit of a tap some times (think lifter) But the problem I need help with is the gear changing When driving along 90% of the time she is smooth and perfect but now and then when I floor it or when crawling at low speed and put foot down she seems to drop down and all I can describe it as is hesitate and then when she hits the gear she wants its a hard jolt and loud bang/clonk!! She don't do it all the time but when she does it sounds worrieing just hoping its not something expensive!! Anyone else experienced this???? She just don't seem to know what gear she wants some times and don't feel like a smooth bmw should do Any advice or help be great The car is a Bmw e38 735i v8 1999 (T) Thanks in advance Sam
