I own 2006 Range rover L322. Long time she had transmission issue but I'm still driving. Problem is harsh shifting.
Tried many things like fluid change, solenoids change, torque converter change, SONNAX kit for mechatronic, sleeves and bridge etc...
Problem still exists. Recently I bought iCarsoft LRII and tried to diagnose my tranny. And found something interesting... Please see below 2 pictures.
This is what my diagnostic software reads.
and this is source from SONNAX.
If compare above 2 pictures my solenoid 2 or EDS2 behaves exactly in opposite way as it supposed to be. And also solenoid 4 behaves something different than SONNAX document.
So my question. Is this normal or my transmission software needs to be reflashed.
Thank you forward for your time.
