Manual is way more fun. Seriously though, nothing beats using the gears to decend a steep hill, but then again, it sucks having to shift in the middle of trying to climb that hill... Gas mileage would be better with manual. More low end power with a stick. Plus it's harder to chirp the tires between first and second with an auto.I am trying to make a decision before I order 2007 Unlimited Wrangler Rubicon. I need to know what is PRO and CON between automatic vs manual transmission.
Thank you for advising if you have answering this question.
nah i quit the water stuff. nah i never saw that issue. petersens 4wheel and offroad is pretty good though. or maybe i should try j rationsThey certainly do suck and they think we suck. Ever see the issue where they talked so badly about jeep internet forums and the people who use them? Now why do you suppose that is?
Anyway, drive your manual through water all you want.
hmmm never knew that thks for the infounk:All the input regarding manual versus automatic transmissions are good.
I would add the following:
Clutch versus torque converter. Clutch is a direct coupling between motor and transmission. This is advantages for downhill work. The direct coupling also gives a little better fuel millage. The down side to the clutch is when a lot of start stop driving is done the clutch will get hot. When hill climbing and feathering is needed the clutch will get hot and can fail under extreme conditions. Think of the cluth as a break pad holding the motor torque to the transmission.
The torque converter is a hydraulic fluid coupling which provides smooth coupling between motor and transmission by means of hydraulic shearing of the fluid. This sheering accounts for the fuel milage loss. A second item is the heat caused by heat sheering. When doing hill climbing and a lot of start stopping the torque converter fluid heats up. If this heat is not removed transmission failure occurs.
Heat in the automatic transmission fluid can be removed using coolers. The heat generated in the clutch is more difficult to remove under continual clutch application. The manual clutch relies on the heat sinking properties of the flywheel and pressure plate for its cooling. This means that if you heat up the clutch and can leave it engadged (foot off the clutch) for a while the heat will be drawn out of the clutch plate.
Now we get to the automatic transmission versus the manual. When looking at the gear tooth contact between the gears on a manual transmission you will notice that on the transfere of power there is only a gear and a half tooth contact between gears. This is a week point for manual transmissions. In Automatic transmissions a planetary gear system is used alowing three sets of gears transfereing torque at all times. This allows for significant tooth contact between gears. This is why drag cars use automatic transmissions.
I prefere automatic for strength and manual for fun.
I respectfully disagree...Because of the clutch packs and the packaging, designers have to go as minimal as possible with the planetary systems.. Hence the teeth of the latter are very fine and need more contact area (3 gears) to transfer the load which the planetary system will provide for. Shock loads in a auto transmission are more easily absorbed whereas in a manual you only have the damper springs in the clutch disk............ When looking at the gear tooth contact between the gears on a manual transmission you will notice that on the transfere of power there is only a gear and a half tooth contact between gears. This is a week point for manual transmissions. ......
Again that might be true for drag racing.. But Jeeps are no drag racers..and I have no issues that you prefer auto transmission but I make exception as to the reason why..I prefere automatic for strength and manual for fun.
Outside the technical jargon just read: Strength wise, your auto is as good as your manual..Hey Antigoon. I dont understand what you meant by it. Could give it in newb language what that mean. I have an auto and so am reading through this thread...
