Hi All,
FYI. http://en.wikipedia.org/wiki/Volvo_XC90
"Many owners of the T6 variant reported very early transmission failures, many before 60,000 miles (97,000 km).⎘]⎙]⎚] Some owners reportedly went through two transmissions in that time.⎛] The GM-sourced 4T65EV/GT transmissions usually show symptoms of failure by suddenly slipping while in gear. There was no recall for this issue, but the faults are widely known and documented. Various causes have been given, ranging from engine coolant entering the transmission fluid to problems arising from Volvo's modification of the original GM valve body⎜] unit inside the transmission, but none has been substantiated. Non-GM-sourced transmissions have not suffered unusual failures of this type.[citation needed]
Many owners of early V8 models in 2005 and some in 2006 have reported problems with the counterbalance shaft. A crevice in the engine block where one of the sealed bearings is located collects water if the engine has been in a wet environment such as washing the engine bay. If the engine is not allowed to heat up and evaporate the water out of the crevice, the bearing will fail prematurely. This issue was addressed and fixed by Volvo by drilling a drain hole in the crevice."
