XC90 T6 – Transmissions Fail

Volvo XC90 model years 2003-2005 with the T6 engine were made with automatic transmissions that fail early and often.

The parts guys at my Volvo dealership told me recently that it’s the XC90 T6′s that are the ones to avoid at all costs. They said it’s a GM designed/partially assembled transmission on these XC90′s that was a pile of junk from the drawing board. They said there aren’t anywhere near the number of transmission problems with the T5′s or the V8 model XC90s.

At 65,000 miles my Volvo XC90 trans is shot. to the tune of $8-9 to repair. Dealer offering to settle at $2,500. Any suggestions?

I’ll just add this here, that the parts guys at my Volvo dealership told me recently that it’s the XC90 T6′s that are the ones to avoid at all costs. They said it’s a GM designed/partially assembled transmission on these XC90′s that was a pile of junk from the drawing board. They said there aren’t anywhere near the number of transmission problems with the T5′s or the V8 model XC90s.

I’d like to know if any of the mods have any insight on this bit of information, as wifey and I are debating buying an XC90 for the space. I’m more in favor of an XC70 only because of the slightly better fuel economy, but that’s another debate altogether…

The 4T65-E transaxle is surprisingly compact given its torque handling capabilities. This is due to how only the torque converter sits aside the engine while the transaxle’s gearsets and valve body are located behind the engine. The limited space available in the S80 and XC90 engine bays meant that not just any transaxle could be bolted up to the T6 engine. …the XC90 has one *very* serious fault that the S80 does not have. That is that the XC90 weighs 1,000 lbs more than an S80. That’s half a ton more weight that the transaxle must contend with. So driving an XC90 is equivalent to driving an S80 with a permanently attached 1,000 lb trailer in tow behind it. No doubt driving an XC90 prudently then would require even more prudence than the lighter S80.

Here’s the XC90 T6 Transmission thread┬áin the Volvo forum for more on that. Please post to that if you’ve had a XC90 T6 transmission failure.
