The car (125K miles) developed a huge leak on the transmission oil. My mechanic tells me that the transmission oil is cooled by the radiator water and it looks like the radiator let loose allowing water to mix with oil. (The radiator was replaced 2 years ago with a brand-new SAAB radiator) I am puzzled. IS this true? Did anyone have similar experience?
Yes it is true, it happened to my 1995 2.3NA 900 at approx 35k miles. I was told it is rare on a 900 but a batch of 9000's had bad rads and SAAB replaced the auto boxes under warranty. Your problem now is to flush the auto box enough times to get rid of all contaminated oil. If the auto oil got into the cooling system as mine did it takes a long time to get it flushed out. I believe the water that gets into the auto box actually boils away when the auto box gets up to temperature, my car was constantly showing the low coolant warning.
