Installing a 700R4

[geoman]

Hey guys,

I am THINKING of installing my rebuilt 700R4 into the 83. Conventional carb 350. I noticed the wiring diagram for the lockout on the other thread but I am a complete knucklehead when it comes to wiring this type of stuff. I was originally going to go with a TH350 but since there is a tight budget I may as well use this one.

I noticed the lockup kits from summit and jegs but they are pricey. Anyone have pics of the conversion and what else is needed? Especially any other cables, electronics, and crossmember. My truck originally had the 1.9 with 4 speed. It is coming out next week.

Thanks again for all the help everyone has provided me so far!

Here Mike. You have part numbers and a diagram.

I tried that on mine and it has not worked yet but I haven't llooked at it since I put it in.

Hello,

Yes that was the diagram I looked at and I am still trying to figure out how and where everythign goes. I am so clueless to certain types of wiring. :)

My best friend knows circuits pretty well and I will let him tackle it......lol

well you dont need lock up in low speed around town driving. and you dont want lock up under heavy acceleration 40% throttle or more as this causes premature 3-4 clutch failure. so just take the square plug on the trans and hook it to a toggle switch and hide it under the dash. if you do 55+mph highyway driving then when you get around 40 or so reach down and flip it on. when you get off the highway click it off before you get off the off ramp. all you need to do is wire the A wire in the plug to the toggle (power) and the B wire to a good ground. all those brake switches and so on suck in my opinion.

wow, this is becoming more intresting...lol

I was just going to ask about the practical application of this, like how I would actually use the switch and stuff, but I think you basically answered all my questions. Im still a little confused about how it works. I flip the switch when I hit highway speeds, but won't I be running at a high rpm? How does locking it up drop my rpm? I can't even explain my question properly, hopefully someone understands what Im trying to figure out though.

Josh, the lock up style converter is like any other eccept for the locking feature. The converter acts normal while driving and allows the slipage to have more engine speed to tranfer the power to the drivetrain. The converter has a stall speed, all converters do. The best part of this converter is the ablity of having a performance feel and the economy of the lock up. As you were saying about the highway speeds. The converter is still slipping about 300-400 rpm. This means the engine is running faster than the trans output. When you are highway speeds, 50mph or more you can use the lock up. When the solenoid is powered in the trans by you toggle switch and the trans is in 4th gear, the soleniod engages the lock up feature. This simulates the same as a manual clutch and flywheel. This actual stops the slipping and reduces the engine rpm to equal the output. This works great for the long time periods of cruising. When you slow down and stay is 4th without using the brakes, the truck may seem to buck. That would only happen if it slows below 50 mph. All you have to do is flip the toggle to turn the power off. If you hit the brake, the system would also power off until the brake is released. This disengages the soleniod and allow the converter to slip again or stall.

That was the explanation I was looking for, thanks. I knew that the lockup keeps it from slipping, I just didn't understand how it reduced your rpm without changing your speed.

You should write a book...
