Verbatim from NHTSA complaints, newest first
“Transmission fluid cooler integrated in the radiator that allowed engine coolant to mix with and contaminate the automatic transmission fluid causing damage to the transmission. Radiator had to be replaced along with flushing out of the trans fluid at a service station costing a few thousand of dollars. Months later the check engine light went on and found out that the transmission is slipping caused by the fluid contamination.”
