What are the main differences between manual and auto gear transmission if theres 1,2 and overdrive in auto?

Question

apart from a 5th or higher gear in manual transmission, can u not control the change of gears in an auto car in the same way as a manual car and achieve the same performance?

Answer 1

In a manual transmission you have complete control of all gears in the transmission by manually shifting through them. But with an automatic transmission, depending on the vehicle most of the time you are only limited to overdrive, drive, 2, and 1st. Which is the same as a manual but you don't have to operate the clutch manually. For example my 96 jeep has the above transmission gear selections and of course neutral, reverse, and park, but I can manually put the vehicle in 1st, 2nd, 3rd (drive), and then in overdrive for complete automatic operation, but the new jeeps have park, reverse, neutral, and drive. and that's it unless you get the autostick option for which then you can manually shift between gears. But for the most part older vehicles have the same options gear selection wise. Performance depends on how you drive the vehicle and how you take care of it.

Answer 2

If I understand your question: How can you manually shift an automatic transmission if all gears are not represented on the transmission selector? In the instance you present, assuming your transmission has four speeds (1,2,3,overdrive), it would not be likely you could hold third gear to red line or down shift into third gear. This is not true of all automatic transmissions. DaimlerChrysler had "Auto stick" and Audi has "Tiptronic" which allows selection of automatic or manual shifting up or down of gears.

Joe- Haynes and Chiltons are the worst manuals you will get your palms on. For Chevrolet you truly need to get into touch with Helm guides. I used to artwork as a Mechanic then moved into the climate branch at a close by Chevrolet Dealership. Helm guides is the employer that GM makes use of for all of their production unit save manuals that the Dealership's use. they are through a few distance the main complete, and contain each and everything your are going to ought to to appreciate approximately your C85S physique Truck. The manuals are 12 months particular and could conceal the "S" form, (4x2) and the "T" form (4x4) for that 12 months. be confident to specify what handbook you will desire. there will be a physique restore, electric powered, music Up, Transmission/very final stress, (Rear end), Suspension/guidance, and Engine and gasoline administration/Emission Controls. they could have them available on CD now too. only notice, they're going to be somewhat on the costly edge, as compaired to the Kragen Crap. yet those contain complete troubleshooting guides for each section. those manuals no longer in basic terms handbook you interior the process the truthfully restore technique, yet in addition they inform you precisely the place the gadgets on those autos are, and the simplest thank you to get them replaced. the only different set of manuals i could evaluate after the Helm guides set are those which are available in from Motor Age. The Motor Manuals are additionally most of the very ultimate ones. yet for GM, try Helm guides first. good success!
