hybrid 1043 Report post Posted August 21, 2007 Take it into BMW and get it on the update computer ... It could just require a software update to the GCU. There are many reasons for this happening, fluid levels, fluid pressure issues or engagement piston issues. Just going through all this sh*t myself with the gearbox shop and BMW with the e46. Fun times.... Quote Share this post Link to post Share on other sites

Jaredsc 0 Report post Posted August 22, 2007 Yeah, mine does it too, I find if you apply the right pressure to the accelerator, it wont do it. Mine does another weird thing - when I am going along a straight, it is in about, idk, whatever gear and when coming to go down a hill, it feels like there is a heavy force holding the car back like it forgets to change down to first or something, anyones do this also? It is a Jatco auto as well. Quote Share this post Link to post Share on other sites
