check the linkage and possible a bad tranny mount..read up on how it works Everyone should have a manual for their vehicle, and the library should have a professional shop manual available, for FREE, in the reference section(make copies of the correct sections) read up and fix it like a PRO! :) good luck-Dave
A transmission that shifts through gears after moving lever to "d" without driver doing anything no clutch pedal
An automatic transmission is a type of car transmission that shifts gears on its own. Therefore, cars with automatic transmissions will not have a clutch pedal and will have a selector lever as opposed to a shift knob.
The year, make and model info would help.
put petrol in it
Lubricate all linkage parts and check for bent, misaligned or worn parts
The shift cable for a 1998 Ford Expedition allows the transmission to be shifted throughout the available gears. It is linked directly from the shift lever to the side of the transmission.
Usually either Park (P) or Neutral (N). Pretty much any car will only crank in those gears, and even if the car could crank in other gears it would probably damage or destroy the transmission
lever at crank, connected by chain to lever at rear wheel
I am unsure what you mean by your question.There is either an analog hydraulic computer inside the transmission called a valve body that makes the decisions or a Electronic computer that directs the transmissionORYour teacher could be looking for "The manual Valve" or "Shift valve" or "Range Valve" But at the end of the day the driver moving the lever shifts the gears.
When the transmission lever is in 'Park' it activates a small rod (known as a "pawl") that slips between the teeth of the transmission gears and locks the transmission at a standstill. It is possible that through age (or mis-use and abuse) the pawl may have been bent or broken (e.g.- someone tried toput the vehicle into 'park' while it was still moving). If you're lucky, perhaps the rods running from the shift lever to the transmission have gotten out of adjustment (or bent) and the lever is unable to activate the pawls action.
a salad spinner uses gears to speed up turning motion. Gears are based on the lever principle. So in essence, yes it is a leaver.
have someone change gears, while not running, and make sure the linkage from the gear lever, whether automatic or not, is moving the linkage for the transmission itself. if the linkage is moving on the trasmission, then its probably in the tranny. also make sure the drive shaft is working (runs from the transmission to the rear differential).
gears, lever, wheel and axle
The first and cheapest thing that comes to mind: is the shift cable still intact? There is a cable between the gear selector in the cab and the gear lever on the transmission. Crawl under the car, put someone inside to work the gears when you tell them to, find the gear lever, and have your friend move the gear selector. If the gear lever on the transmission does not move, the cable is broken.
The transmission linkage connects the shifting the lever in the passenger compartment to the shifting lever on the transmission. You will find the shifting linkage on the side of the transmission.
check for leakage from trans master cylinder to slave cylinder at bellhousing. other things. ?? worn synchronizer gears / worn clutch
There is a Left Hand Lever on the handlebars whick you can pull. That pulls on the clutch which allows you to change gears by kicking up a small lever a little bit forward on the left foot peg. To start off, you hold down the clutch lever, kick up the foot peg lever to 1st gear, slowly give it a little gas by twisted the throttle just a little bit, and then slowsly let go of the clutch hand lever. While riding, when you need to change gears, just hold down the hand lever, kick up to the next gear, and then you can let go of the hand lever. Hope this helps.
on the turn signal lever. it rotates forward to be activated
If it still has a reverse, just in the wrong place, then the linkage or cable from the shift lever to the transmission has streched or fallen out of alignment.

I change the gears in my mower with the gear shift lever located on the right rear fender.
