I have no problems with my e53 transmission so I never bothered with getting it for the e53. I found some pics of XHP on a e53 with the gear display enabled- top is Drive; centre is in Neutral, bottom is in Sports mode.

But to answer your second question. After servicing my 6hp26 with aftermarket seals, Valvoline Multi-Vehicle Synthetic ATF, and resetting trans adaptations, the 2-1 slam was gone immediately. And it was a severe slam, like getting hit from behind @ 10mph.

I contacted xhp flashtool to see what their product can offer. They said their software is built on the latest bmw software so if a bmw software update was to cure my issue then xhp should also do the same. The price was around $320Au for the license and 3 maps. I would probably only use the stage 1 map if I got it. I've been trying to find a good review of xhp with a diesel to see what it's like. |

Maybe that wasn’t necessary if XHP are suggesting it updates it anyway. I tried stage 1 for five minutes of driving and seemed no different to stock, so I then flashed stage 2 and to me it was still pretty mild . I’m on stage 3 now and in sports mode it shifts much faster but not harsh . In normal mode even with stage 3 I don’t think anyone would really notice. In sports mode with stage 3 as you slow it rev matches, which I think is dumb for a diesel. There’s no way to disable that except by either just using stage 1 or 2 or just drive in normal mode . There’s other options available to customize any of the stages - lock out or enable 6th gear in sports mode; Valet mode, drag race mode, and change when it upshifts and downshifts through the gears, rpm limit , and a few other options.

Although ista-P is simple to navigate, it’s very limited in options. No choice which version you update to, and various modules all tied together. Also I used an ICOM to connect it to my e70 . Also must have big amp power supply. WinKPF is what you need for e53, but I haven’t used it to update my e53. Maybe because my e53 is an august 2006 build , it already had a later update version.

I took the leap of faith this morning and ran the software update for my transmission. After researching how to use WinFKP a bit more and understanding how it selects the software numbers after I select my gearbox I gave it a try and it worked. I charged up my battery overnight with the small ctek charger and left it connected. My battery is only a couple of months old and from my research the update takes 20-25 mins so I crossed my fingers and it held out. It is a tense 25 mins while its happening.
Did it solved the 2-1 harsh downshift? Almost, it does drive very nice now and i'm glad it is running to latest software for that model gearbox. It does seem to shift from 2-1 a little before it comes to a stop which makes it less pronounced. If I roll really slowly to a stop I can reproduce the 2-1 bump so hasn't cured it 100% but its less present. Having the fluid and seals changed has definitely made it much better to drive. It must have low on oil because it always used to have a strange shift from 1-2 when turning when cold, almost like it would fall out of gear for a second. This would only happen when cold and went away once it was up to temp. Since having the fluid and seals changed this has not happened again. |

Have you tried it and if so what were the results like? I keep reading conflicting views on resetting them so it's hard to know what the go is. |
