We have a 2004 Volvo XC90 with about 88000 miles on it. It has been regularly maintained by the Volvo dealer from which it was purchased. Recently a “Transmission Problem” message appeared and the transmission has started to slip and fail to shift when it should. We took it back to the dealer and they quoted $9000 for a rebuilt transmission and a required replacement of the transmission cooling system.
I don’t have that kind of money so I took the car to a local mechanic instead. He is quoting $3000 for a rebuilt transmission, but also recommends replacing the cooling system for an additional $2000. The mechanic could not really explain why the cooling system needed to be replaced.
I can understand the need to replace the transmission, but why is it necessary for the cooling system to be replaced? The transmission fluid looks clean and there’s no smell or discoloration as evidence that it has overheated. Can’t the existing cooling system be flushed and left as is?
