M45 tranny snatching , hesitating etc. What was done to the 04 model ?

Postby yidal8 » Wed May 12, 2004 5:03 am

All this has been discussed before , but :I had the tranny TSB done to my 03 M45 , but no improvement . The tranny TCU does not like to talk to the engine ECU . Still some hesitation , and violent downshifting , extremely hard downshifting some times , other times it is O.K. etc . Someone said earlier that the 04's have this problem fixed . My service Mgr. says absolutely no change to the drivetrain between 03 and 04 models . Is it possible that Infiniti snuck in some kind of a software fix ?

I would unplug the battery overnight and see fi that fixes it.

I tried this already . It may have improved this slightly , but only for 1 day maybe . I drive pretty agressive , no Granny the Tranny for me . ( 15-16MPG combined 50-50% Hwy / City )

That's lame... Adaptive trannys suck.. My friend has one in his XJR.. anytime his dad drives it, it adapts to his slow *** grandpa driving.. then when he gets it back he has to floor it all the time just to make it learn not to drive like grandpa..

I dunno why they all have to do this..

If you floor it it shold downshift to the optimal gear/rpm point asap..

If people dont want massive power, dont buy a v8... stop trying to take big engines with adaptive slow trannys...

Have you tried driving with the VDC turned off? I have made this a reflexive habit - whenever I start up my M45, I turn off the VDC and it behaves a lot better!
