| Well, gus, at least we said the same thing! | |
| My 93 firebird doesn't properly shift into fourth gear. One mechanic said to disconnect my battery so that the computer could reset itself, another says to look into having it replaced. Can these trannys be repaired or am I looking at replacement? Thanks. | |
| Well, is it a standard or automatic? (I'm guessing automatic). Is the fourth gear an overdrive setting, one that can be controlled by a switch? | |

My tranny died! Went to back up and no Reverse. Just sits there and makes a whirring noise...(like your tires are spinning when you are stuck in the snow) Mazda 323 '89 automatic overdrive 1.6l. I called local mechanics and much to my dismay I was quoted an average of $1900 to replace it. Parts and labor. The car has 124000 miles, needs a timing belt replaced and a valve cover gasket. (again!!! =( ) All of this work is way outside of my price range. Any suggestions on what to do? Should I just have it towed to a local junk yard or what? |

| Either that, lapis, or get a good used tranny to put in, but I wouldn't spend more than $500 parts and labor....better to put the money toward a new(used) car for $2,500 or so, if you need basic wheels that won't break down. | |

Hey guys, here's one I've wondered about for years. Overdrive - What is meant by "electric" overdrive? What are the other kinds? Is this one of those cases where the wrong term was adopted and then became the standard term? It seems to me that any ratio greater than 1:1 (that is, any time you're gearing "up"), is an overdrive gear. By this definition, a lot of cars' top gear is an overdrive. What is the difference between a 5-speed trans (with greater than 1:1 top gear) and a 4-speed with overdrive? |

I am confuse too, I guess overdrive is sth can keep the gear shifting at high rpm to avoid damage to engine and tranny, when the car is over loaded. Is that right? |
|
| The firebird is an automatic. I don't know how the overdrive is controlled. I'm assuming it's electric or computer driven since a mechanic told me to disconnect the battery to let my car "reset itself." | |

Originally, and technically still, i guess, overdrive was a separate (planetary)gearset of sorts, so you could have an overdrive gear not only in top gear but also some of the lower gears. My old MGB was electrically operated, but I could get 1st, 2nd, 3rd, 3rd overdrive, 4th and 4th overdrive...so it could be used like a 6-speed transmission. Now, most 5th gears on a 5-speed is an "overdrive" gear. I haven't had the automatic overdrives apart so i don't know much about how they work, but I don't think it's a oomplete additional gearset...I'd need to hit the books and look at some diagrams. Maybe someone can save me the trouble? |

| On Volvos, I know that the 5-speed transmission, where you actually shift into 5th gear, rather than press a button to activate the overdrive, is a single transmission, without a planetary add-on. I'm not saying this is true of all 5-speed transmissions, but on a Volvo it is. | |
