Before to go with any software-upgrade, check again fluid level (its tricky so do it serval times to confirm it is right) and condition (should be cherry red now not brown, clear not cloudy, and it should smell like fresh ATF not burnt) ?? Also make sure that you got the right oil very important as you know.
Then, go to a Volvo dealer to have checked and cleared error codes, check this out. A jerky transmission shifting also can be due to a bad spark-plug. Finally if you still experience those symptoms, a 2-3 gear slippage could also be due to a bad Torque Lock-up solenoide in your Valve-body. Personally I do not recommend aditifs which certainly will modify your ATF characteristics and can give prejudical issues to your tranny.
