we have a 2008 X3 3.0i bought used at 91k and now have 121k on it. Been wanting to change the trans filter and fill for a while and havent had time.
Local indy shop says its not a simple as just drop the pan and change the filter and fill. Seems all will come out. (9.5 qts) about $470 to change out. $120 for filter kit, $150 for 9.5 qts synth fluid and $200 labor. would prob do the transfer case too as I dont think any of the driveline fluids have been changed.
Ive read that it was a GM trans and (i assuemed) like all my other GM trans I just drop the pan, change filter and add few quarts till its full but now I see that there are 2 possible transmissions One ZF GS6X37BZ and One GM GA6L45R how do I tell which one I have and do they each require diff procedure?
