Reliability concerns with the GETRAG G360 are often connected with towing over long distances as the transmission fluid can reach relatively high temperatures. When this occurs, the effective lubrication properties of the lube oil degrades and the bearings have a tendency to wear rapidly until ultimately failing. On the contrary, there are many GETRAG transmissions in service that have been extremely reliable and rugged; it is therefore unfair to presume that the transmission is inherently flawed. While Dodge calls for 5W-30 engine oil, many owners suggest that switching to a 15W-40 engine oil and overfilling the transmission by 1 extra quart alleviates many of the towing pains the transmission has been known to exhibit.
