those wires are the only wires holding me back from removing the main computer harness and was wondering what they where.

i believe they are the converter lock up wires but i am not sure

 

Two are for the converter lock-up. The 3rd is a 4th gear indicator - tells the computer when the transmission is in overdrive.

 

are any essential for keeping the trans operating properly

 

You need to keep the torque converter lockup functioning. The tranny won't remain happy if you cruise without it.

 

could i put in a manual lock out switch in its place

 

You can use a manual switch to provide the function. There's a tech article about it.

 

5.7 is correct trans doesn't like it. If your already working on the thing pull the trany pan off and change the filter, while your there you will see the three 3 wires, 2 go forward to the lockup solenoid and 1 splits off 4"to6" from the plug and goes to the rear of trans to a pressure switch. Then you can see what goes where to do your lockup switch. good luck

when you are at the thirdgen.org homepage go to technical articles. and there should be a link that says something about lockup converter switch under the transmission section.

heres the link

https://www.thirdgen.org/torqueswitch

 

Saw that, but I am wondering about best way to lock up the TC with no computer in the car at all.


Thanks

 

The method in the tech article still works without a computer, as long as the wiring hasn't been hacked up.

 

my method will work with the harness hacked up see my pic

 

With your method it will auto lock in 2nd third and 4th correct?

 

with the switch in the down position it will lock in 2nd 3ed and 4th with it in the up position it will lock just in 4th. i also ran the ground threw the cruse break switch.

 

Sorry to hijack the tread, but as i was reading through this, i reallized, hey, my 200-c tranny has a 3 prong connenter with 3 wires going to it.. now it being a 3 speed auto tranny with no override what is the 3rd wire going to? (2 to the tourqe coverter lockup, 3 wire is for???) thanks guys.. just wondering on this one.

 

ok i have nev3r heard of a dpdt switch
what is one and do you have a pic and can you get one at oreilly auto or napa or auto zone ?


thanks!
