95 4runner 4x4 6 cylinder Automatic - O/D doesnt work Plus Etc.

vehicle : 95 4runner 4x4 automatic 6 banger



O/d doesnt engage

When i push the o/d button on shifter.. No light on dash comes on..

Shifter light doesnt come on.. checked bulb and its good

Ashtray doesnt light up, checked Bulb its good..



I noticed that the shifter light is using the same plug/connector as the o/d swith..



has anyone had this problem?.. im wondering if there is a Fuse.. that controls all of these?..



also.. i tested the O/d switch with my multimeter.. and it came out to 2.1 is my switch * on shifter * good?



what are the specs i should be getting?

can someone help?



Shiftter assembly instrutions would also help..

wiring diagram for o/d**.

shifter console light**.

ashtray light**



Thanks again guys.. I just want to use O/D again..

all wiring here!
Index of /wiring

as for your overdrive issue i bet its the overdrive shift solenoid.

 

[rhd91integra]

does anyone have the voltage numbers for the o/d switch on the shifter?

also..

does a relay.. give power to the shifter console Light * lights up thep/r/2/3/d*... same relay go to ashtray?...


P.S - over drive shift solenoid is in the oil pan correct?

 

[fourwd1]

The OD solenoid is mounted on the side of the trans right above the pan.

Update :

This is what the Original Owner of my 4runner said.. Before the O/D off light would flash.. and O/d wouldnt engage.. Before they sold the car to me.. the O/D off light just wouldnt Work at all.. * pressing the o/d button wouldnt do anything *.. and O/D was Lost all together..

I tried jumping the terminals and getting the Codes.. NOTHING.. NO CODES at ALL.. NO O/D off light on my Dash.. and NO o/D at all.

I got no code to work off of.

The Only idea i have is from the troubleshooting manual for the transmission
A340H. Disconnect the O/D shift solenoid.. and run the tranny manual through the gears.. and i still have NO O/D its a Transmission problem.. If i do have O/D.. its gotta be electrical..

But why No Codes then? and No o/D?.. doesnt make sense to me..

THanks for reading my RANT.. Help would be GreaT!

straight from the FSM
i guess if that light doesnt even come on when just turn the ignition on then it would tell me the solenoid is shot or a bad ground.

Diagnosis System
DESCRIPTION
1. A self–diagnosis function is built into the electrical control
system. Warning is indicated by the overdrive OFF indica–
tor light.
HINT: Warning and diagnostic trouble codes can be
read only when the overdrive switch is ON. If OFF, the
overdrive OFF light is lit continuously and will not blink.
(a) If a malfunction occurs within the vehicle speed sen–
sors (No. 1 or 2) or solenoids (No. 1 or 2), the over–
drive OFF light will blink to warn the driver.
However, there will be no warning of a malfunction
with lock–up solenoid.
(b) The diagnostic trouble code can be read by the num–
ber of blinks of the overdrive OFF indicator light
when terminals TIE, and E l are connected. (See
page AT–56)
(c) The throttle position sensor or brake signal are not
indicated, but inspection can be made by checking
the voltage at terminal TT of the data link connector
1.
(d) The signals to each gear can be checked by measur–
ing the voltage at terminal TT of the data link con–
nectar 1 while driving.
2. The diagnostic trouble code is retained in memory by the
ECM and due to back–up voltage, is not canceled out
when the engine is turned off. Consequently, after repair,
it is necessary to turn the ignition switch off and remove
the MFI fuse (15A) or disconnect the EC M connector to
cancel out the diagnostic trouble code. (See page AT–56)
HINT:
Low battery positive voltage will cause faulty opera–
tion of the diagnosis system. Therefore, always check
the battery first.
Use a voltmeter and ohmmeter that have an imped–
ance of at least 10 k
v.
CHECK ”O/D OFF” INDICATOR LIGHT
1. Turn the ignition switch ON.
2. The ”O/D OFF” light will come on when the O/D switch
is placed at OFF.
3. When the O/D switch is set to ON, the–O/D OFF” light
should go out.
If the–O/D OFF” light flashes when the O/D switch is set to
ON, the electronic control system is faulty.
AUTOMATIC TRANSMISSION – Troubleshooting (Diagnosis System)
AT–54
• In the event of a malfunction, the light will flash 1 time
per second. The number of blinks will equal the first
number and, after 1.5 seconds pause, the second
number of the two digit diagnostic trouble code. If
there are two or more codes, there will be a 2.5 sec–
onds pause between each.
HINT: In the event of several trouble codes occuring si–
multaneously, indication will begin from the smaller value
and continue to the larger.

try a reset of the ECU to see if you can get a code.
disconnect the battery and then reconnect it

hey guys.. Long time No see

My younger brother borrowd my 4runner for 2 months

anyways

I unplugged the tranny shift solenoid plug.. and im changing gears manual.. L to 2 to D.. i have OVERDRIVE when i unplug the shift solenoid plug on the wiring harness..

When i plug it back in.. i put the car in D and all i have is 1 2 3 NO OverDRIVE

FUDge cAKES.. Now my ECT Light wont even come on either.. ** forgot if i already had this problem LOL *

I tried looping the tranny temperature sensor.. and that didnt help.. Im gonna have to wire it back up again.. Since i cut and Looped it.. * doh *

What else can i try?.. I know my Oil Temperature sensor is Out.. It doesnt have a reading at all

is that a problem?

 

[fourwd1]

Have you applied 12V to the O/D solenoid to see if it works?

 

[Bad_Vision]

is the engine coolant getting warm enough to turn on the OD???
