I got a lockup kit from TCI and the wiring instructions are useless.Anybody know how the wiring should be? it says to disconnect 1 switch (and not use it) and install a new supplied 4th clutch switch with 2 pins.Theres a solenoid with 2 pins and something at the end of 2 wires that run thru a plastic "Z" holder, not sure what that is. I got to hook up to 1 ground coming in and 2 power feeds.

I'm having trouble wiring my TCI lockup kit.The instructions suck! Can anyone identify the switches and/or solenoids and explain what they do? If I knew that ,I'll have no problem wiring it up. Thanks

your photo shows the OEM wire harness. Where is the lock up kit stuff?


IF you want lock up in OD only do this:

The silver switch with the green colored plastic connector.... move the black wire from the lock up solenoid to this switch.

Then however you wish , you need to hook the red wire from the l/up solenoid to a 12 volt power source . Obviously you need to connect the red solenoid wire to the case connector so a 12 volt source can be hooked up.

With the wire setup I have provided the tranny will lock the converter up in OD each time when 12 volts is at the tranny solenoid red wire.

Not sure of your instruction troubles. The sheets I have seen provide the proper information.

I opened up the tranny to check my wiring.I have 12 volts feeding the brown wire.The black jumps to the coil. The red from the coil goes to one terminal of the new 4th clutch switch.The other side of the 4th clutch switch goes to ground. Does this sound OK?

Does anyone know what is this pce. is called and how does it work? Current doesn't flow thru.I checked with an ohmeter.

the picture you show is of a temp sensor used in the tranny. Nor sure exactally what it does, but mine has one too.

Hopefully Crosley can help you out some more.

that part is a normally open bi metal temp switch( large black end on wire harness) which will close at 275 degrees and then it will use the normally open 4th gear switch(green end on harness )for ground for lock up if ecm failure or no ground for lock occurs.you can use a paper clip to cross that terminals and apply 12 volts to the a terminal and lock up will be about 2-3 miles an hour after 4th gear. the middle switch (with red ends) is called 4-3 discreet switch (normally closed) use to break the 12 volts on 4-3 down shift.

I have no ecm as this is in a 76 chevy.Instructions call to remove the wires from the 4-3 discreet switch.Is this OK?

Put the switch in the oven and she's working fine.Thanks

if you install paper clip across temp switch reinstall plug that will complete circuit for ground, then install a 12 volt key on fused wire to the a terminal. leave everything else alone this works I use the same method all the time, no need to buy the lock up kit..... some people want a more complexed system but this works. there are many ways to rig lock up this is only one....

[123pugsy]

OK , so now i've got 12 volts (A) to the temp switch which I know is working.From there it goes to the coil in series then in series thru the 4th clutch switch to ground on the (D terminal) How's this sound.Will it work?

I guess what you are calling a coil (?) is the lock up solenoid. red & black wires from it.

This is a simple 12 volt DC circuit.

Power to the red wire.

Black solenoid wire to the silver switch I pointed out many posts earlier. The silver switch is self grounding. Do you know what "self grounding" means? When pressure is applied the switch closes which provides a ground.

You may need to splice a wire or two for the 12 volt power for the solenoid through the plastic case connector. The case connetor is where the wires plug into on both sides of the aluminum case.

Cut and remove all other wires. THe temp switch & all , remove them , unneeded, dont use them.

[airworld2]

this sounds tuff but is the most simple thing to do on a 700.....

[123pugsy]

Thanks.I know what what self grounding means.It means I'll just leave the 2 pin switch thats in there now and run the ground out thru the harness.I've got a vacuum switch to put it thru.I'll just jump the power across the temp. switch to bypass.How about the 4-3 discreet switch? Do I need this?

Hey airworld ,thanks for your input also.I"ve got no problems with electrical once I know what the parts are and what they do.

[123pugsy]

OK,so now I think I've got it.The temp switch is not necessary.I will bypass that and give the solernoid (red wire) 12 volts.The black from the solenoid runs thru my new 2 pin 4th clutch switch to ground.I'm assuming the 4th clutch switch only closes with pressure to allow the circuit to ground thus allowing the solenoid to lock up the torque convertor.Simple, huh?

So now I think as per my original post ,I know the parts and what they do.

Thanks.

sometimes we are clear as mud here.

It is a simple process for the lockup wires.

if more problems arise , simply ask..
