How to wire a switch to lock up the torque converter?
Attach 16-gauge wire to the “on” position of the toggle switch. Route this wire through the rubber grommet in the firewall and down to the transmission. Direct the wire through the transmission wire harness grommet and attach it to the positive side of the TCC solenoid. Install the new filter into the transmission by gently pushing up on it.
How does the torque converter lock up on a 700R4?
Torque converter lockup on the 700R4 transmission is controlled by the TCC solenoid. When the solenoid is engaged, fluid is applied to the torque converter clutch, creating lockup and a direct link between the engine and transmission.
How does the lock up function of a converter work?
The lock-up function is accomplished by solenoids that control the flow rate, and hence the usable pressure of pressurized transmission fluid to vary the amount of converter lock-up.
Where to install a torque converter clutch solenoid?
1. Install jumper wire in place of the trans relay in the Power Distribution Center (black box behind driver side battery) as shown in diagram below. This jumper wire will supply 12 volt positive to the transmission torque converter clutch solenoid. This jumper will be electrically hot thus it should be installed so as not to short against ground.
Where is the lock up switch on a torque converter?
The ECU grounds the circuit to control the operation of the torque convertor. So in order to install a switch to force lockup, all you have to do is hook up a grounding circuit. 1) Locate pin #53 on the ECU. They are numbered on the ECU. 2) Tap into the pin #53 wire in the engine management harness.
Torque converter lockup on the 700R4 transmission is controlled by the TCC solenoid. When the solenoid is engaged, fluid is applied to the torque converter clutch, creating lockup and a direct link between the engine and transmission.
How to wire a torque converter to a car?
Connect the 10 amp fuse block (without fuse installed) to the positive battery cable, and route the wire through a firewall grommet, into the vehicle. Attach the constant side of the toggle switch. Attach 16-gauge wire to the “on” position of the toggle switch.
1. Install jumper wire in place of the trans relay in the Power Distribution Center (black box behind driver side battery) as shown in diagram below. This jumper wire will supply 12 volt positive to the transmission torque converter clutch solenoid. This jumper will be electrically hot thus it should be installed so as not to short against ground.
How to install torque converter in GM 4L60E?
Spin the torque converter and push in towards the transmission. 2. Listen and feel for three distinct “clicks” as the torque converter engages each component (input shaft, stator support and pump rotor). Measure the distance between the torque converter mounting pad and bell housing face to verify torque converter is fully installed.
What’s the diagnostic code for a bad torque converter?
A faulty torque converter clutch solenoid normally sets a Diagnostic Trouble Code (DTC), which causes the Check Engine Light to come on. A faulty torque converter clutch solenoid will normally set diagnostic trouble code P0740. » A problem in the Transmission Control Module (TCM) or Powertrain Control Module (PCM), depending on the vehicle.
What kind of wiring does a Chevy Blazer have?
WIRING INFORMATION: 1989 Chevy S-10 Blazer WIRE WIRE COLOR WIRE LOCATION 12V CONSTANT RED Ignition Harness STARTER YELLOW OR PURPLE Ignition Harness IGNITION PINK Ignition Harness ACCESSORY ORANGE Ignition Harness POWER DOOR LOCK (5-wire reverse polarity) LT.
What kind of transmission problem does a Chevrolet have?
Newer Chevrolet cars, equipped with a 6-speed 6L80 transmission, can experience sporadic or constant transmission issues. This ranges from harsh or slow shifting, failure to engage any gears, or gear slipping. In some cases, it may even cause transmission overheating.
Why does my Chevy transmission not go into 3rd gear?
Chevy transmission won’t shift, stuck in 1st gear or limp mode – Speedometer may also display zero at all times. It could be internal transmission failure, low transmission fluid, or faulty Vehicle Speed Sensor (VSS sensor). Chevy transmission won’t go into 3rd or 4th gear – This is a good indication that 3 or 4 gear clutches are worn.
How to test a torque converter without uninstalling it?
Remember to not release the brake pedal. With one foot on the brake pedal, press the accelerator all the way for 2-3 seconds with the other foot. Be careful not the exceed 5 seconds or the transmission could blow out.The stall speed is the RPM the engine maxes out at.
What happens when a torque converter goes bad?
Higherstall speed – When issues in the torque converter worsen, it will take more time for the transmission to engage the engine, leading to irregular engagement and consequently, total failure.This problem can affect transmissions with lock-up converters more severely than it does others.
How long does it take to stall a torque converter?
With one foot on the brake pedal, press the accelerator all the way for 2-3 seconds with the other foot. Be careful not the exceed 5 seconds or the transmission could blow out.The stall speed is the RPM the engine maxes out at.

Direct the wire through the transmission wire harness grommet and attach it to the positive side of the TCC solenoid. Install the new filter into the transmission by gently pushing up on it.
What should I do if my torque converter is failing?
If you keep on driving, you risk the converter circulating metal shards through the transmission, and you’ll end up having the whole thing replaced. A rather simple test can determine whether the torque converter is failing.This is how to carry it out: Turn the ignition key and start up the engine.
With one foot on the brake pedal, press the accelerator all the way for 2-3 seconds with the other foot. Be careful not the exceed 5 seconds or the transmission could blow out.The stall speed is the RPM the engine maxes out at.
Can a torque converter clutch be unplugged?
Unplugging the torque converter clutch will not harm the transmission or cause it to overheat. This is just a regular three speed automatic transmission with the TCC lock up feature. When the TCC solenoid is unplugged it reverts the transmission back into a regular automatic three speed.
What should I do if my GM converter lock up?
NEVER run the vehicle in gear when supported only with a jack. Chock the drive wheels and apply the parking brake. In addition, some of the tests (test #11 and 12) require the transmission be opened and the valves are physically inspected. I do not recommend that you do this.
What causes the torque convertor clutch to disengage?
There is a solenoid in your GM converter that causes the the torque convertor clutch (TCC) to engage and disengage. When the TCC solenoid receives a signal from the engine control module (ECM), it opens a passage in the valve body and hydraulic fluid applies the TCC.

Can You unplug the solenoid on a GM converter?
Generally, if you unplug the TCC solenoid at the transmission and the symptoms go away, you have found the problem. But sometimes this can be misleading because you don’t know for sure if it’s a bad solenoid, dirt in the valve body or a bad signal from the ECM.
