Manual Torque Converter Lockup

Hey all gurus in the nissanpatrol land,

I'm thinking of putting in a Manual Torque Converter Lockup mod in my Troll for when I start towing with it.
I sort of understand how it works but have no idea how to make it. Has anyone done one and/or have a list of parts and instructions???
I think its mostly electronic set-up so I'll be able figure it out if someone has a diagram...
If there is any mechanical work I could be in trouble...LOLOLOLOL

Thanks in advance:cheers:

I think Chaz will be the man to answer this question.
Or you could just look at his website; http://www.chaz.yellowfoot.org/Locku...s%20Switch.htm

yeh Kris as Tony has already posted.....Chaz is tha man

From all my readings from various places on Manual lock ups Chaz is defiantly the man 2 speak 2

Juland electronics is the mob that make them NissPat . they have a great web site , check them out , worth a look .

Wholesale Automatics do a kit as well I think...

Mine cost me less than $30. In its simplest form you need a change over relay, 2 metres of light gauge wire and a switch but I added a flashing LED so I knew if it was armed.

Simply put the relay in the wire to the Lock Up Solenoid so that NC is the ECU signal and NO is 12 Volts and common is to the Solenoid.

MY switch was an old school foot operated dip switch I screwed to the foot rest. Dab the swith, locked up, dab it again and back to ECU control.

Some guys have waazanga setups that are speed sensitive etc but I didn't bother

If you go simple then you need 5 parts
1 x Changeover Relay ($10)
1 x Switch ($10)
1 X LED ($6)
Approx 2 metres of wire
Crimps to suit Relay

Cut the wire (should be pin 22 but check) from the ECU to the Solenoid and connect the ECU to 87A, the Solenoid to 30 and the 12 Volts from the switch to 87 and 86 and earth to 85.

If you are switching Earth instead of 12 Volts connect 12 Volts to 87 and 86 and 85 to the switch and the other side of the switch to earth

Hiya Todd

... not as often as I'd like too, unfortunately :redface:

Thanks boys, exactly what I was looking for.

Looking at Chaz's s diagram I love it but it might be a bit of an over kill for me as I just want it for towing. Don't really need it for 4wd stuff, so I won't need the momentary switch side of it or the brake side...very cool indeed tho.

I'll stick to something simpler like ET has posted as I just want it for keeping the tranny cooler and better economy. ET, do you find the flashing LED to be enough to remind you TC is locked? Do you ever forget? LOLOL

Anyway, I'll go and visit Jaycar to see what goodies they have.

EDIT, ET the ECU you are referring to, is definitely ECU or TCU, Also, mine's a CRD

Can some one confirm this setup is OK. Sorry, just did it in Paint so bit average

This is just a simplest of mods

Right, time for a dumb question from me - happy to ask them though!!!

Are we talking a manual torque converter lockup that can be switched on or off whenever the driver selects it? I didn't think the converter would lock up at all until certain gear/speeds were achieved?

This is something that would interest me also, as I think my turbo is giving the converter a hard time - if cruising and converter is locked up, apply a bit of power to go up a hill and it doesn't drop down to overdrive or third - simply holds whilst the turbo spools up a bit of power, but the converter seems to have a bit of a hissy fit with power applied and "misses/slips" as such...

Not well explained, but if you're with me, am I potentially burning out the converter and should do this mod also?

Sorry for the slight hijack Kris!!
