    Need help with 4l80e not shifting right.

    Ok I will look at the diagrams and let you know which wires you need to hook up. The problem with using 2 sensors on the transmission and then a third 1 in the transfercase is when you are locked in 4 low the computer will not recognize it because it is getting its readings before the...

    Need help with 4l80e not shifting right.

    Yes it makes perfect sense. Typically a 4x4 truck equipped with a 4L80E will have a plug in the OSS hole, the VSS in the tailshaft of the transfercase is what is used for the second sensor. If the Transmission was a 4X4 transmission it more then likely does NOT have a reluctor wheel inside...

    Need help with 4l80e not shifting right.

    Ok if you unplugged the OSS and the transmission is shifting is is VERY possable that is your problem. Unplugging the OSS makes the computer substitute values via the ISS and continues to command the shifts. More then likely if you drive it with the OSS plugged in with a scan tool plugged in...

    4x4 indacator

    89S is correct so I am not gonna dispute the information he has provided. But I am going to suggest an alternative route. IMO It is best to avoid running Ignition Hot or Constatant Power wires thru the firewall, or any other part of the truck where shorts can happen. yes I know in theory your...

    Need help with 4l80e not shifting right.

    Sounds like a pretty cool swap, Few questions for ya though. You say you cut down a factory harness for the swap? Absolutly nothing wrong with using the factory harness BUT, what computer are you using? Others have already stated Gear ratio changes. Which is for good reason, the transmission...

    Multi-Port EFI discussion...

    First let me say it is ulimatley your decision to make, It doesnt make a difference to me either which way. BUT IMHO I beleive the newer OEM fuel injection would be a better choice for interchange, reliability, and honestly efficency. Even the oiling system is much more improved over the...

    TPI= Nice reliability, Hard to find at times. LT1= Is a hell of a set up, I'm sure it could do really well in a truck, IF you delete the Optispark. Vortec= Is a reliable setup and proven in the trucks, Yes they have issues with the spider (injector), but they do have the conversion for...

    Looking at New tires Help needed!!!!

    naw the wheels are actually off of an 06 chevy. Walmart is funny about some things, but its because most of there workers arnt smart enough to do a job right. So they avoid any comebacks they can rather its a lug stud broken, or a wheel lock nut with no tool.

    ou know Hotrod there is another possability that is not even electrical that may be causing your issue. The ECT Sensor is designed to be submerged in coolant when its threaded into the head. If there is an air pocket around the sensor It will NOT register. Doubt that is whats wrong with it...

    You are correct grounding the sensor wire does tell if you hasve continuity on the circuit, BUT it does not tell if there is exsive restinace. Connect the terminal to ground, just like you did to spike the gauge. Then go to the cluster pigtail. Find the sensor wire, then connect the...

    Well the warning light is not controlled from high or low resistance. It is just a Normally Open switch that just happens to be temperature controlled. To know what the ohms of the Switch is you need to think about "ohms law" which is. V = I x R (Voltage = Current multiplied by Resistance)...

    Function testing factory Gauges.

    To accuratly test the gauge you would need a potentiometer that can read from 1600 ohms (100*) down to around 90 ohms (250*). But you can still test the sensor circuit with voltage drop tests all the way to the gauge. Fuel gauge sending unit is 0-90 ohms 0 ohms and the gauge should read...

    Hold on there grass hopper... Doesnt mean it is the gauge. The problem could still be in the sensor lead to the gauge. Remember HIGH restitance means LOW temperature. You do need to get access to the IP plug. then do a voltage drop test at both ends of the wire. It could very well be the wire...

    Function testing factory Gauges.

    Something I like to always try to do to my vehicles when I have the coolant system empty, is to remove the drain plugs in the block. Then install a spring loaded ballvalve in place of the plugs. That way if I need to change a coolant part I can simply atach a hose to the valve and run it into a...

    Function testing factory Gauges.

    The gauge itself has 3 wires 1. 12 volt ignition hot 2. Ground 3. Signal wire from sending unit. An easy way to think about how the gauge works is to think of it as a RELAY. The gauge is constantly grounded via the ground wire, when the ignition is in the run position 12 volts are applied...

    Function testing factory Gauges.

    You have a DVOM? Just do a voltage drop test. Set your volt meter to DC volts, Touch negative lead to Battery negative POST, then touch your Positive lead to the case of the sending unit. Observe voltage reading. Anything more the .03 - .05 volts is excessive. Another way to test for...
