when driving in D (never noticed it in sport more OR when I shift gear), BUT when holding the speed 35-50 km/hr, like around school zones, my tranny seems to be missing. its fine one second then i feel a power loss and it seems like its searching while in that speed.The RPMS are not jumping around at all. SO I'm kinda thinking software or something electrical. If I am accelerating through that speed i never ever feel those symptoms. the last week I've been kicked out of my home for an upcoming house reno and while I'm driving in from Bearspaw, I find the same symptoms are sometimes occuring now when I've cruising at 80km/hr. So I'm thinking of getting a fluid change and ask the guys to remove the pan and take pics of the valve body and solenoid colors and the tag plate so I can order up a rebuilt vb from RevMax Converters for the following reasons:
This is what makes a RevMax ZF 6HP valve body superior to the rest:
Billet anodized solenoid regulator valve
Upgraded solenoids featuring aluminum ball seats that replace the factory plastic seats

PLUS I figure I've got 200k kms on him now and he costs me very little money (will be doing vcg soon and perhaps other preventative maint in engine bay soon) but its still cheaper than buying a newer X5 (and I'm only thinking of a 2012 ////M X5 or newer) if I had to go that route. May as well make the leap a JUMP if I'm going that far.
a few thousand in maintenance at Witeks and he'll be good for another 10 years I think
