1994 k2500 4x4 wont shift in to 3 and overdrive


This year of GM Transmission doesn't have a vacuum modulator, it is all electronically controlled. And yes a shift solenoid can cause this but that should turn the check engine light on and set a fault code.

Solinoid etc


There are many solenoids in your car, what solenoid are you looking for?

Running normal then just stopped, cranks Ok ,Battery good


My 83 camry died one day on my way to school. I noticed that while I was driving my lights started diming then the engine just shut down. Found out that my alternator was dead. In your case have your alternator tested, your battery charged and check to make sure you have the belt that turnes the alternator and note if there are more than 3 cracks in the ribs of the belt per inch, I would replace the belt while you have the alternator out.

Where is the EVAP purge valve at on a 2004 subaru forester


The purge valve solinoid is on top of the engine to the left of the alternator. It has an electrical connector and two smallish hoses, one to the intake manifold and one to the purge valve. Inspect both hoses for cracks and dry rot. Make sure you get them installed correctly. The one closest to the solenoid is to the manifold and the one at the end to the valve.
Disconnect the battery before replacing the valve.
A Common cause of OBDC errors. Some code readers can cycle through solenoids, tests AutoZone may not trouble with.

Got. A 2003 f150 4x4 got problems with 4 wheel drive locking in and stay in drive shaft turning front wheels not


Operationally vacuum shifts the front axle between 2WD and 4WD mode. The GEM ( Generic Electronics Module ) applies ground to the solenoid needed for the mode selected on the switch ( for ESOF ) or when the transfer case shift lever is moved ( MSOF ).The contact plates in the transfer case signal the GEM that the transfer case is engaged, and the Vacuum solenoids need to be activated ( either 2WD to 4WD or 4WD to 2WD ).

Lift and support the front of the truck so the front wheels are off the ground ( take safety precautions, chock wheels, jack stands, etc )
Key on, engage 4x4 and try to turn the front drive shaft.
- If it turns it is a problem with the transfer case.
- If it doesn't it is a front axle engagement problem ( this is what you seem to have, the transfer case is engaged and will drive the front shaft mine was a key on engine off test ).

- If the front drive shaft does not turn :
•With the truck running ( with front wheel back on the ground ), switch from 2WD to 4WD and back again, the vacuum shift motor should move the lever on the front axle.

-- If the vacuum shift motor does not move:
1.Check for vacuum on the lines while shifting between modes. Pink vacuum line is 2WD mode, Light Blue vacuum line is 4WD.
2.Check the fuses for the 4WD system and the solenoids.
3.Check the vacuum lines from the vacuum shift motor to the solenoids on the firewall.

4.Check the vacuum lines from the solenoids to the vacuum reservoir box behind the battery.
5.Check the vacuum reservoir box for cracks.
6.Typical solution is the vacuum lines ( to the solenoids or to the vacuum shift motor ) are cracked or the vacuum shift motor has a cracked diaphragm and has water in it.
7.Could be the shift plate contacts in the transfer case are corroded / not making good contact, and not activating the solenoids.

Usually the case is cracked vacuum lines from the solenoids, the next common is a cracked vacuum reservoir box, and 1 time I have seen the mount for the vacuum disconnect motor broken ( motor floating free so it could not push against the axle )

1989 Ford F150 5.0 Auto 2wd. Was Driving in the city and all of a sudden the truck started stumbling lost all power and turned off. Got her towed home noticed the ground to battery was cracked replaced...


If the positive cable is on the wrong side, yes no power. The positive must be on the up side of the solenoid along with the other wires (except your start wire which goes on the small post). The cable going to the starter hooks on the down side. The ground goes to a ground (usually to the motor).

How do you connect alternator wires to the starter


There is only one wire common to the alternator and starter and this is the main+ wire which goes from the alternator down to the main feed terminal of the starter solenoid from there it runs to the battery + terminal.If you are replacing the cable use one of the same diameter......

WHATS INVOLVED IN CHANGING A SHIFT SOLENOID AND A CONVERTER SYLANOID IN A 1997 SIERRA 4X2 CAN BE DONE EASY BY A NON TRANSMISSION SHOP A 4L60E 3SPPED OD AUTO TRANS


No that hard, but your going to have to drop the Transmission pan, there are two identical solenoid at the back of the valve body with the pan removed.
The "B" (2-3) solenoid is the closest to the passenger side,"A" (1-2) is closest the driver side.I would go ahead and replace both as they are not that expensive.Spring clips hold them in place that can be removed with a small screw driver.
The "slipping" you're noticing,is most likely just the transmission shift pattern getting screwed up due to the malfunctioning solenoid.Probably more like a 1-2-2-1 or a 4-3-3-4 pattern depending on which way the solenoid is failing,or maybe it feels like it is starting out in 2nd or 3rd gear. 

Once you get the solenoid changed and transmission fluid and filer changed, here is a little added performance you can do. Have the Servos replaced with the Corvette servos, the part is only $45.00 and take about 30 min to replace but less for you since you have the truck up on a lift already. 
Good Luck and here is a link for the 4L60E improvement. http://s-series.org/component/option,com_tech_article/Itemid,/item,6/task,item/
