Does anyone know of an upgrade to this trans for an LSD? Or would replacing the 2WD diff with an AWD diff be an improvement? Parts pics of the diffs show them as nearly identical so I'm not sure if it's a possibility or not.
Looking to stop the TCS from triggering during power-on cornering. Disabling the TCS is not a good option as the inside tire then spins uncontrollably. This car would corner drastically better with the improved grip of LSD.
AW55-50SN Differential

The LSD that I know of that fits this application is out of production. I've driven one and the cornering wasn't any better at speed than a good set of tires and TRACS. The tracs system is faster/smoother than an LSD so an enhanced set or track day set of tires worked best for me - especially in high speed corner entry.
At very slow speeds or in the snow LSD was nice. I'll see if I still have a link to the old diff.

Here is a quote on how someone did it.
. There are to my knowledge two manual gearboxes for the FWD cars, the M56 (available in H and L versions) and the M59. Some people have gotten the M66 from the S60R to work in these cars, but I will focus on the 850's offerings. The M56 has an open differential, but is supposedly stronger than the M59. The M59 however, was used in Europe in the R's, and came with a high power-handling clutch and a limited slip differential. The M56H and L differ only by gear ratios, both being very strong transmissions. When using the Volvo manual transmissions, the R clutch kit should be capable of handling most builds regardless of driving style, until you start approaching the 350-400 whp level. In my car with 19T turbo, stock injectors and intercooler, and Upsolute tuning, I ran 13.31 at 107.4 mph, this with the M56H transmission and R clutch.
