Dear expert,

my 2004 year volvo car need to do transmission fluid replacement, could you help to recommend which brand now is best replacement? the old spec i was using now is discontinued. can i use this one? thanks.

Valvoline Multi-Vehicle (ATF) Full Synthetic Automatic Transmission Fluid 1 GA

 

which make/model Volvo do you have? Generally, the recommended fluid is listed in the owners manual which you can then google for compatible specs. You can also research based on the transmission model (also listed in the owners manual). What was the old spec you were using? If you have a five speed automatic, most likely you will require a fluid that meets the JWS 3309 spec but there's not enough info here to say that's it with certainty.
