whats a governor??
i know engines pretty good but when it comes to transmissions i'm lost. my question what is a governor, whats it for. somebody told me once that taking the governor out helps performance is this true?

To save a lot of typing, it (along with the modulator/kick-down/TV cable) tells the trans when to shift up/down. Leaving it out won't allow it to shift, in fact it won't work at all. I believe they were talking about removing the "accumalator" spring, this will make it shift "hard" at all speeds (very annoying for a daily driver). Maybe someone (KULTULZ especially) can provide you with a link to learn a lot more about this subject. The Internet is sooo cool! :)

Governors are very simple devices on Auto transmissions. As BestMech says, it is just one of several inputs the trans needs to do it's job properly. Remove it and the trans can't do anything 'cause it has no information.

They are located on the tail shaft and consist of a couple of spring loaded weights that are connected to a slide valve in the fluid control circuit. It is a 'speedometer' for the trans, i.e. the slide valve is all the way in when the car is not in motion but as the car takes off and gais speed, the weights are thrown out by centrifugal force, overcome the spring tension, and move the slide valve proportional to the speed of the car. Thus the transmission has the information it needs to change the shift points and severity for optimal shifts. People who know their stuff play with the size of the weights and spring tension to get the shifts they want, just like you do with the centrifugal weights and springs in an ignition distributor. The typical hobbiest or racer needn't worry about the governor except be sure the springs aren't broken and the slide valve works freely.

Is that what I have heard some drag racers take out to make it a manual transmission with no clutch? 10-18-2002 02:45 PM

Don't know.

To turn it into a full manual, The governer is no longer needed, as is not the kickdown linkage, modulator, etc, but a special valvebody is needed. What this person is talking about rremoveing is a governer on the engine, a speed limiter, these are confined to small engines and tractors, etc, doesnt apply to cars. Newer computer controlled cars have an electronic governer that retards timing and/or shuts off fuel to kkep you under a certain speed, this is 90 and up model years... No matter how you look at it this guy doesnt make sense...

are you saying i don't make sense or the guy that told me this don't make any sense.

JdOwNj 10-19-2002 04:30 PM

The guy that told you this didnt make sense.... im not seeing any way that what he said could apply to cars...
