Hey, thanks. I see you guys know what you talking about. The way I understand is that
1) Code cleared - no change.
2) Remove the pan and replace fluid with synth. up to the previous level?? (No dipstick)
3) Look for the pressure solenoid "inside the tranny" and replace it.
4) If no better - replace transmission.
Or before doing it maybe give dealer a try???
If I've got it right - please let me know. And if you have ANY questions on VOLVO F series trucks - I'm your man
