| Being in the automotive repair business for 25 years, I look at the cost of repairing a tranny against both fuel economy and the cost of repairing a worn out motor. If you don't use overdrive on the highway at 60mph to 75mph your engine is running a lot higher rpms than it's used to running at. It'll also run hotter and usually use some / or more oil than normal. If you trade your truck every couple of years, it's not much of an issue. If you keep it for any period of time, I'd rather have the immediate fuel savings and pull the tranny if it goes rather than having to pull a motor. Down time is a lot less with a tranny, too. For me anyway, the cost of a rebuild is the same on a tranny or a motor. The tranny is just a lot less work and shorter down time. | |
