jonesrp 63 Report post Posted February 15, 2014 I`ve googled this and it seems to be possible with just a quick wiring change. At the moment I push forward to change up and push back to change down. I think this may have been reversed as standard in later model e39`s. Quote Share this post Link to post Share on other sites
yng_750 247 Report post Posted February 16, 2014 wrong section to post this but i believe it has two small touch switchs that the lever pushes. either swap switches or swap wiring to reverse the system Quote Share this post Link to post Share on other sites
jonesrp 63 Report post Posted February 16, 2014 That`s apparently the answer. Cheers.. Quote Share this post Link to post Share on other sites

rowans17 19 Report post Posted February 17, 2014 I've done this. Just pulled all the trim off and traced the wires back from the steptronic switches. Then just cut them and swapped them around. worked perfectly and quick easy job. 1 Quote Share this post Link to post Share on other sites

vtgts300kw 90 Report post Posted February 19, 2014 I don't understand why some manufacturers insist on getting this wrong. it's just infuriating. Because not everyone thinks like #racecar. It's probably more natural for "normal" people to think the other way around. Quote Share this post Link to post Share on other sites
Mr2low 57 Report post Posted February 21, 2014 Still need to swap the + and - around otherwise it's just silly Quote Share this post Link to post Share on other sites
jonesrp 63 Report post Posted February 21, 2014 I agree that it`s a matter of choice but this topic appears on other Bmw forums. It just seems to feel unnatural to me in factory setup. So I`ll give it a go, I`m not worried about the + and - , a later owner could change it back if they wanted to. Quote Share this post Link to post Share on other sites
_ethrty-Andy_ 2132 Report post Posted February 21, 2014 what are we saying the correct way is? up/forward to change down, down/back to change up? Quote Share this post Link to post Share on other sites
yng_750 247 Report post Posted February 22, 2014 Acceleration pulls you hand back so pulling shifts up. Deceleration pushes you forward so down shift go forward. Thats the theory in race cars where they are a very firm shift anyway Sent from my GT-I8160L using Tapatalk 2 Quote Share this post Link to post Share on other sites
jonesrp 63 Report post Posted February 22, 2014 That`s it in a nutshell Jason. I was reluctant however to describe acceleration as throwing the 528 driver back in the seat. . Quote Share this post Link to post Share on other sites
RustyItalian 11 Report post Posted February 23, 2014 The easiest place to swap the two wires on an E39 is at the transmission computer in the engine bay. Doing it at the gearstick is far too fiddly with too much bloodletting. You simply take the lid off the ECU stowage, pull out the trans ecu and remove the bosch connector. Identify the two wires per the wiring diagram, release the connector and swap them. Completely reversible. Quote Share this post Link to post Share on other sites

I had thought about doing this but now I am used to it the 'wrong' way so it doesn't bother me much anymore. Quote Share this post Link to post Share on other sites
