I had a 1998 G30 with a 6.2L diesel (w/700R4) I towed with it a good bit and it really irritated me when the TCC would unlock when you pushed more that like 3/4 throttle. This might have been good practice for a gasoline but the diesel didn't need it. I also wanted lock for long hills in lower gears. I directly wired a switch to force it to lock. It drove fine and I found I could just leave it in lock almost all the time. (This is not good practice on ice or is slippery conditions as it really needs to let go when you push the brake.) But the real issue showed itself about a year later when reverse failed (never used lock in reverse) It turned out that the engineers, in improving efficiency, actually valve off lubrication to bearings that were not being used in 4th(and lock up) but are in lower gears. That meant any time I was in lock in the lower gears I was eating bearings. Finally a seal failed and caused the reverse to fail. I discovered that I could grind a flat spot on one of the valve body spools and keep the lub active. I also discovered that later model trans had this done at the factory. I swapped the 89 van for a 92 which I have to this day and still use the lock almost all the time. Due to the design of the trans it will not lock in first even if the switch is on. I wired a toggle switch on the shift leaver and turn it off when stopping and back on when I reach a cruse. as it bothers me to lock it under hard load. But I lave it in lock when it down and up shifts etc. ( I didn't used any pressure switches) I am trying to figure out if I can do something similar to my 2012 T&C...

By far the best video I've seen on this! Thank you 😊

Excellent video. Thank you. I appreciate that you explained the project and all the little details 'this goes here, that goes there and here is why'. Good stuff!

Great job. Keep it up!

Cool! Thanks for the info

Thanks for video man

Very nice job, great information!!

Another great video.👍

Great video I appreciate the content keep delivering

Very good video my brother you would be an excellent instructor..

Brilliant..nice one .cool truck too

On A 89 trans you ground it to the 4 th. Gear pressure switch and run power out to brake light switch - if it is carborated ? . If FI leave it stock. With the stock 2 wire TCC solinoid. Nothing required just move a wire. Eliminate 3rd wire. This is the easiest way to get the TCC solinoid working, no kits or any other parts. I'm not sure how the earlier two wire switches work but I think that they could work with one side grounded on fourth gear pressure. I have a single wire on my van with the earlier 700r4 for TCC lockup. That is probably grounded through a fourth gear pressure switch. I'm guessing that. I do remember that I just hooked up one wire from the brake light switch, on with pedal released, so it has to be turning on by the fourth gear pressure switch grounding The TCC solinoid. And it shuts off by the brake light switch.

Mine has 8676358 in big numbers (like 1 inch tall) just above the pan on driv. side. Also on drivers side, to the right of that number is a 2 wire connector

I’ve watched a few of your videos. You are so good at clearly explaining and showing the process involved. Very detailed videos with great camera work. All the issues I’ve been having with my 350 and 700R have been resolved by watching your videos. Thanks man, keep up the awesome work!!

I'm watching this because I found a 700R4 and don't know anything about it, nor, have I ever had one before. I do plan to use it , but I want to know as much about it as I can learn before I do use it. I'm hoping you can help me identify which one I have because the ID numbers are missing. If you are interested in helping me, let me know and I'll make a short video on it and perhaps you can help. Let me know, OK?

Thanks

Quick question, why would it stall at a stop light if TCC is not disengaged? shouldn't it be released when coasting and transmission comes out from 4th to 3rd? Great video by the way, loved the relay setup.

Great video, if you use your third gear pressure switch, it will lock up in third gear. Also, am I correct?

excellent video...subbed... going to check out your other videos.. thank you

Instead of relay couldn't you use a brake light switch with cruise and use the cruise as the cut off?

do you have any info about tcc lockup in th200c?

Another good video man. The brake switch interrupt was necessary because as you begin to slow down from a 4th gear cruise, your clutch would potentially stay locked up and fight you trying to decelerate??? Never thought about all this, but that makes sense. Sitting at a stop light you really shouldn’t need the interrupt from the brake, right? Fourth gear solenoid has already let go and the clutch should be released. Am I missing something? Was nice to see a new video from you man. One of my favorite channels. Clay

thanks! I know... videos had to pause for a while so I could take care of a few things... but I've got a bunch in the hopper, so time to get back to work and get them posted! Thanks for watching!

oh yeah... to answer your question - I've heard both ways are true - some say you HAVE to cut it off, coming out of 4th gear on its own won't un-energize the solenoid. some say you HAVE to shut it off or the engine will stall. that might be another one of those "depends on the model" things. using that handbook I figured out mine was originally connected to a vacuum switch, which cuts off the electrical signal once the vacuum switch goes below a certain vacuum level. most guys I talked with say to wire it through your brake switch. it's easy enough and then there's no doubt. hope that helps!

@@GODSPEEDGarage It sure does. Glad to see you back posting. take care, Clay

Does this setup eliminate the constant lock/unlock on the torque converter? Thanks, Charlie

I have the 2 wire solenoid, my question is, if I connect the power side to a manual switch controlled relay, will it only activate when there is enough pressure or when the switch is on?

On my transmission, (1985 w/ Type 4 wiring), that pressure switch only has one prong. However, the one beside it has 2 prongs. Would it be ok to swap them since that one will no longer be used?

I just found this video, it is the best one I've seen, do you know the part # for the external pressure switch? The link no longer works,thanks,Rick

it's a Superior K013. I just fixed the link. Thanks for letting me know it wasn't working!

do you know how to wire up a turbo 350c lock up converter?

700r4 transmission lock out

I was wondering if your transmission has the cable or or not I know that some do and some don't the 1 I have has the cable. I know the cable is mainly used to control line Pressure Anyway I was just wondering if your transmission has the cable or not

Okay that doesn't make any sense! The one wire solenoid is grounded on one side of the coil wire correct? You installed the two wire solenoid and then did exactly the same grounded one of the wires. So why did you install a two wire solenoid if you were going to ground one side of it anyway? Am I missing something?

When you ran th truck without it did you just leave ghe wires going to nothing or leave the plug out?
