What are the requirements for volvo transmission fluid?
High-Quality Volvo transmission fluid is recommended for use in transmissions made by Aisin AW requiring a fluid approved against Type T-IV, JWS 3309, GM 9986195 and Audi G-052-025-A2. These AW (Aisin-Warner) transmissions are used in some domestic and foreign vehicles, including Audi,Toyota, Saab, Volvo, Volkswagen, and Porsche.

My 1999 S-70AWD auto transmission …orange arrow flashes and the car’s RPM zooms up if I try to go above 45 miles/hr.
Dealer says that the transmission is faulty needs replacement. I had volvo transmission fluid changed at 70K miles (currently at 90K) by a local reputable transmission shop. Dealer says that the fluid used was wrong (normal ATF Dextron III) and caused the failure.
The transmission shop indicates that the original manual indicates Dextron and that is what was used. Dealer says there was a service bulletin (section 4, group 43, number 0029) and the shop shoud l have used synthetic fluid (JWS 3309). Transmission shop say that SB applies only if there is hard lock (which was not there at 70K mils)
I am not sure who is right….I am looking at huge bill. I have gone back forth between the two …none is taking the responsibility.

In this case, your dealer is right and the transmission shop needs to fess up and do what’s right. Starting in 1999, the clutch materials in the Aisin Warner tranny used in the S70’s were changed. For proper operation, they require a special type of volvo transmission fluid with proprietary friction modifiers, which can only be found in Mobil type 3309 fluid or the Volvo transmission fluid made for the car, which will run you $18/quart. Normal Dexron III / Mercon fluid will lead to transmission failure. The special type of fluid is supplied in these cars from the factory and should be the only fluid ever run in them. The dealer is right about the service bulletin also. The transmission shop should’ve used the Type 3309 fluid. They are giving you the run-around and doctoring Volvo’s service bulletin.
