• Another BMW question - my E61 (manual) sometimes jumps out of 1st when you go to pull away. Seems to happen a lot more in hot weather (and when Mrs Hammer is driving) - any reason for this inconsistency? Could it be solved by a gearbox oil change?

  • Might be cured by an oil change - could be due to it being low on oil. Or it could be worn synchros. Probably worth treating it to an oil change before resorting to open box surgery.
