"fewer controla?" Yea, it's hooked to a computer which depends on, like you said, inputs from at least 5 different sensors. The older trannies (w/vac. modulators, and the later ones, w/TV cables/linkages) were simple, and generally easier to service. The "kickdown" lever you're referring to was nothing but a valve connected by linkage to a valve in the valve body (later, that job was also handled by the TV cable/linkage, ) Not to mention, it was a hell of a lot easier to figure out what was wrong with those older trannies. -LMB |

An auto has the advantage here, obviously. No, it doesn't. That's what your parking brake is for. Or, you just don't have the dexterity (either because you're a klutz or haven't practiced enough).

Anyone with a manual that lets a car roll back -at all- needs to get either training or an auto. Harry K |

Anyone > with a manual that lets a car roll back -at all- needs to get either > training or an auto. > Note that given a 6% grade or steeper, some 4-cylinder AUTO transmissions (e.g,. Toyota Corolla, Nissan Sentra.) will even roll back a bit until throttle is applied. In other words, just letting off the brake pedal starts a rollback, until throttle is actually applied. The only difference is that in an auto transmission, one can hold the brake with the left foot while applying moderate throttle, then release the brake when the vehicle starts to roll forward. Furthermore, there is a third method of not rolling back even in a manual transmission that if often frowned upon, but it can be done. That, of course, is holding the vehicle stationary on the incline by maintaining the clutch in a "halfway" position while applying very light throttle. Do it too often, though, and I understand that the clutch can eventually burn out. |
