Question about Toyota Cars & Trucks
I've got a 2002 toyota 4 runner I need to know where exactly in the transmission solenoid B is, it has a 755 code come up
Inside the transmission
it is an electromagnetic to hydraulic valve. so needs to be
in the valve body to do the shifts,
all this and more is in the FSM, (shows the tests too)
and at alldata.com

Trans model is the 4L60E,and the shift solenoids are mounted on the valve body,just inside the bottom pan.There are 2 shift solenoids,one EPC solenoid (Electronic Pressure Control)One TCC PWM solenoid (Torque Convertor Clutch,Pulse Width Modulated),one 3-2 kickdown solenoid,and a manifold pressure switch.As far as a shift solenoid relay switch,i have never heard of that.The power for the transmission solenoids comes through the ignition switch ,and uses a fuse,not a relay.Accessing the solenoids only requires dropping the bottom pan,and the valve body does not have to be removed,to change the solenoids.The shift solenoids are the TWO solenoids right side by side and look identical..They are the only two solenoids inside the pan that are in fact identical.Good luck.

Dave, The P0700 code is a generic fault code indicating the the TCM (transmission control module) has recognized a problem and the P0755 is the indicated problem. I'd recommend you check your transmission external electrical connector for water intrusion and corrosion at the terminals by disconnecting the connector. If nothing appears wrong, I'd then recommend you drop the lower transmission pan and take a look at the residue deposit that is laying on the bottom of the pan. You should only see a relativily minor amount of grayish, black clutch material residing there. Pay particular attention for a gross amount of this or any large particular material, including any metal, either filings or chunks, or any brass or aluminum. If this checks out to be fairly clean, then I'd recommend you replace that "B" solenoid (2-3 shift solenoid) and have the trans. pan and filter replaced.; I'd also highly recommend you have the trans flushed for anyother particular matter that may reside internally inside the transmission. You'll have to have the codes cleared and the transmission relearned for shift feel, at that point.

Free registration, wealth of information.
For the record: if the sensors they're referring to are the input or output shaft speed sensors, they are very easy to find...just remove the air intake box (where the air filter is) and they're right there on top of the transmission. Input sensor is the one closer to the front of the vehicle, output towards the rear.
