Is there a vacume line to the Transmission on an 02' Toyota Corlla? If so where is it located on the Transmission and on the Engine?

plugs, coils check also add some fuel injector cleaner to your tank

a vacum modulator does not prevent a car from shifting into gear. Usually when a car fails to move, internal parts of the transmission break and sometimes shatter prevent the clutch pack from functioning. The purpose of a vacum modulator is to allow the transmission to shift smoothly from one gear to the next, but now on allot of cars these days transmissions are solely controlled by the computer. If you transmission does have a vacum modulator then your will find a steel vacum line from the engine going to your transmission with short pieces of hose connecting the lines together.

it may be a bad transmission modulator valve located on the side of your transmission,vacum operated. a sudden downshift or forward shift when unexpected is sign of a bad modulator valve or a vacum leak to the transmission.best to shop around for a garage w/references when it comes to transmission work though. check all the vacum lines to your transmision,you need to look on the underneath side of your truck on the side of transmission for a loose or disconnected vacum line on the side of the transmission. when you feel the vacum line,follow it to the top of engine,the vacum line is about 3/8th line,and may be disconnected or losing air. to make this short,when you drive the car,start out in low gear and shift the transmission,manually from 1st to 2nd to 3rd does it do right with no slipping? if it does this right and shifts great manually,the modulator valve on the side of the transmissions bad,or a bad vacum leak in-between.thank you for choosing fixya.com

check for a bad vacum to the modulator valve on your transmission,or a bad vacum to the modulator valve on the transmission. the modulator valve to the trans. works off of vacum from the engine,look for loose or disconnected vacum lines around the carb. or the air induction system. look for cracked vacum lines that seem to be sucking air when engine running at idle speed. in park. the modulator valve [usually] located on the drivers side,of the transmission,is the main cause of shifting failure. if the valve itself is bad, it will need replacement. thank you for choosing fixya.com!

suggest you check for a vacum line off that goes to the transmission modulator valve, which controls the shifting in transmission.or may possibly just be a bad modulator valve on the side of the transmission. 1st check for a vacum line off, with engine running do you hear a whistling or air sucking sound on top or rear of motor? if so, follow that sound to a hose or small black hose thats off.if you are driving the car and start off in low drive and can manually shift to upper gears with no problems,your problem is either a vacum line off, or it's a bad modulator valve on the transmission. hope this helps!!!

there should be two tags either on the core support under the hood right around the radiator cap one will be the emmisions standards which will have the smog component locations and vacum lines diagramed and the other usually has the belt installation diagram one or both of these will say what size the motor is usually in really small print depending on the maker.
almost all automatic transmission shift by the use of vacum. if you have a broken ,loose ,or disconnected vacum line that is bleeding off vacum when it shouldnt be. then when you ingauge the vacum cylider on the transmission and have the brake pedal depressed the vacum is being depleted to the point that proper air fuel ratios are not being attained and the car dies. vacum is a very necassary part of the volumetric efficency of your motor and is required in order for the motor to run. check the vacum lines for splitting cracking and being disconnected. exspecially around the regular service points oil filler cap trans dip stick ect. this is where you'll usually find one to be damaged or dislodged.

speedo not working could be they put the new transmission in and did not connect or the gear is missing or the wrong type .

sounds like vacume assit module is bad or not connected in the back of the transmission is a brass colored bell shaped part with a vacume line attached right above the tansmission pan follow the vacume line could have slipped between the engine and transmission and is kinked or wasnt connected at all wich could be the case if your speedo isnt connected abs light could be because you have a vacume leak because the vacume assit module isnt connected.

Yhe starter is in the front side of the engine. To remove it u have to remove the radiator first (you will need 10mm socket). the you will se the starte almost at the bottom (you will need 14mm deep socket and also a small extention is going to be uncofortable but is easy) by the way the stater is attached by to bolts onr you will see easy the otherone is in the other directtion hidden away just keep in mind is a 14mm.

The TPS is inside the throttle body. A picture depicting the throttle body is below:
