Code 24 is a vehicle speed signal sensor fault, the sensor most likely does not provide a useable signal until about 25 MPH, when the computer doesn't see any signal after that speed it turns on the light. Make sense?

Here is how I do it. Hope this helps.

AT Fluid Level Check (No Dipstick)

Fill through Check/Fill plug on the bottom to the rear of the transmission oil pan until fluid flows over from hole. Install plug and with engine running, shift transmission through all gears. With transmission in PARK and engine running, remove Check/Fill plug and add fluid as needed until it flows over from hole. Transmission oil temperature must be 86° to 130° F (30° to 55° C)

SOURCE: leak from transmission hose

I'm assuming your talking trans fluid is leaking out a vacuum hose. If this is the case the modulator it plugs into is leaking. Replace the modulator. if this is not what your talking about then more info is needed.

Where do install vacum lines install at on 2000 isuzu rodeo 5 speed transmision


which engine 2.2L or 3.2L?
4wd or 2wd?
2000 Rodeo, no job stated?, was trans removed?, engine pulled?
what?
what makes you think the A/t trans uses vacuum? if true.
what lines to what? all vacuum lines to every thing, that it?

what country,? our USA cars , all have EPA vacuum maps under the hood, open engine hood, look up, see that sticker
and yes, some times it skips vacuum lines to brake booster or trans. its only for smog that sticker, so...
but is helplful
what you never said is what engine you have , as that greatly
effects vacuum routing, on all cars. made on earth.

im on line and there is no vacuum map.drawings
it only shows jobs, pulling lines by step, (marking them first)
no words on vacuum for tranny at all. (no vac. modulator now)
booster
EVAP
all VSV valves
PCV
FPR (fuel pump reg)
Throttle body
Electronic Vacuum Sensing Valve (EVSV)

please state number of lines disconnected,
and if both ends disconnected (a horror)
if confused, show photos. of dangling lines

open the FSM book and see each step, for connecting lines
say the booster hose (huge) it says, connect the booster
hose to the large nipple on the Plenum, (its the only one that fits)
Etc. see hose where does it go, it goes to an object.
the object has a name, like VSV for evap so that hose is called
out in the FSM

factory service manual or alldata.com log in and read, it is there.

The light come on for the 4wd on my 93 dodge Dakota le but will not shirt in


Check the two vacuum hoses on the right
front side, of the front axle housing

You can use a hand held vacuum gauge, to check
the vacuum modulator & see if it will lock the front axle

Have to have the front end up in air & supported &
turn wheel/tire by hand, as you apply vacuum

Keep in mind with 4 wheel drive,only the right rear &
left front are driven wheels,not all 4

If the front axle locks in, with you pulling a vacuum & you have no
vacuum at the front hoses,then go to the transfer shifter & next to
it,is the vacuum switch

MISSING HOSE ON TOP OF TRANS ? WHERE IT CONNECTS?


If it's the hose to the vacuum modulator on the trans, then the other end should be connected to manifold vacuum. Look for an open port on either the throttle body or carb (whichever you have)... Hope this helps...;-)

1994 chev s10 . the air condition vents in the mid dash does not work properly. the air is ok but comes out of the heat vent at bottom. after a while, it will start puting out some air in the mid vents but...


check underneath you hood, on the driver's side, there is a little ball lookin thing. there should be a long skinny hose that connects to it. if it is rotted out or has a leak, your vents will not change over because they are vacuum powered. the vents switch by using the vacuum coming from that long skinny hose. check the entire hose because it splits off into many other things and runs from the little ball thing under the hood on the drivers side and runs along the firewall toward the passenger side. mine is starting to rot and i need to change it as well. any kind of little vacuum leak from that hose will either make your vents move slowly or not at all. im not a gm technician, but i did replace the head on my 2.2l 94 s10 with a Chevy tech. he noticed that those particular hoses on my truck were dry rotted and told me what they were and what it did. like i said, the hose will start at the ball looking thing under the driver's side of the hood, run down behind the plastic piece thats on top of the brake booster and run along the firewall towards the passenger side. you can just get new hose from autozone or carquest and cut it to your lengths, as long as its the same size width wise (or thickness). good luck. its really not a big deal, and its a good place to start and see if it helps.
