On some cars the fourth gear select had two wires to the pressure switch and the switch simply connected them. You might have to bend it ever so slightly back in order to lock it back. Check out my page for a complete list of all of the relevant parts, part numbers, and sources. I did a few mods to the automatic transmission to make it hold up better towing the 4500lb electrical trailer. The throttle valve cable controls transmission pressure.

Have you figured out which port the switch is screwed into? What do I have to do to use a 700-R4 trans with a carbureted 350 engine? Many times this is caused by overheating the transmission. You can go a click or two on the adjuster either way from here, but no more. The next four photos show the internal wiring inside the transmission pan - there was quite a bit inside here on my donor transmission! Although not flathead related, I can answer your question somewhat. It shows the three wires coming out of the wiring plug on the transmission and the basic location of the wiring plug in relation to the shift linkage. It will fix a 700R4 that has really firm shifts, or shifts that feel to sluggish.

I'd guess that if that is true all one would need to do is figure out which hole to install the correct stud in and mount the cable housing. My 52 is stock but not running at the time. Operating the transmission with low hydraulic pressures can very quickly result in transmission failure. If you have anything you would like to post here about the 700R4 e-mail me. I'm told that I should try just hooking +12V to Pin A and tape off Pin D. Because if a car sits, the seals dry up and leak.

In a braking situation the brake switch disengages the converter for me. This wire is connected to ground only when the pressure switch closes going into 4th to lock up the convertor or it will be grounded if you use a second manual switch attached to the B terminal to manually lock the transmission. Or you can figure it out and create your own kit - it's your choice and your money. This wire will provide the power to your circuit. I am looking for the information and pictures on how someone modified their Bell crank on the center carb to accept the cable in the correct arc.

Overheating is the number one cause of transmission failure, making an aftermarket cooler highly recommended. I have done the search, and have seen the 1-800 hot rod sources for this, Bow tie overdrives. You might be able to scab something together for less, but the wiring is different in different 700R4's. Press the transmission pan back onto the transmission and hand-tighten the bolts that secure the pan to the transmission. A car used on a daily basis usually does not have this problem Do your homework before buying a car with a 700R4.

Moving to an overdrive gearbox does have some special considerations to keep in mind in terms of space and controlling lockup and line pressure, though, and in the case of a fully electronic transmission, overall control. Also, anybody know about how much power a 700r4 can handle? Online: Easy, safe and getting more cost effective. You can drill a small hole in a non visible area, and fasten the wire to the chassis using a screw. I would recommend using the correct connector instead of your two wire one. This lead is connected to the solenoid power lead inside the transmission, and gets power when the solenoid has power applied to it. The cable must be adjusted so it is pulled fully out at wide-open throttle. This circuit controls everything via the ground side.

What's Needed to Install a 700

Step 7 Once you have the connector plugged into the transmission, take the end of the red wire from that connector, and strip the end to expose the bare wire. Sometimes I forget the converter is locked up and I'll bog the motor. I have 2 videos covering the mods I did here. Crimp a female spade connector on each end. Apparently he's done so many of these that his kid sat down and designed this bracket that bolts to the center carb lever. The piece in the middle of the drum is what broke off and shattered. This is the most critical part to these transmissions, so if you have any doubts on setting up this system, redo it until you feel 100 percent comfortable it's correct.

Please don't send me any hate email saying that the 2004R is the best tranny since sliced bread. I control the lockup on the converter manually. A re-manufactured transmission will also include a : three years compared to an average 90 days for a rebuilt transmission. Introduced in trucks in 1993 and rear-wheel-drive passenger cars in 1994, the 4L60E and its later, beefier descendents, the 4L65E and 4L70E are fully electronic, computer-controlled transmissions. The first photo shows the wiring connector on the driver's side of the transmission with the three clipped wires coming out of it - look closely, it is there in the grime and dirt. I didn't really film the rebuilding, cause honestly I didn't know what I was doing, and it took about 6 months, hour here, hour there.

Now crimp on the female bare metal connector. Be careful, and make sure that the salvage yard guarantees it to work. Transmission oil is usually red or green while engine oil is a golden color. No first hand experience mind you, but it does kinda make sense. The final photo shows the underside of the transmission case connector - the white plastic piece is clipped into the transmission housing and there are plus that go into it from the top and bottom - it's quite a complicated little piece! Feed the red wire coming from the male connector through the fire wall and crimp on a female spade connector by striping a small section of the end to expose the bare wire, then crimp on the connector. I've learned a lot over the winter rebuilding my Chevy automatic transmissions. You could in theory substitute a self-grounding switch here as well and only have two wires coming out of the transmission case, but I'm not sure at what pressures the various switches trigger at.

Strip the end of the wire and crimp on a male spade connector. Failure to hook-up the throttle cable in this way will burn the three-four clutch pack up fast. Be careful whenever you go to meet somebody. I was planning on converting mine over to mechanical, took off the little pulse gear whatever you call it then promptly lost it. That could be due to my transmission being rebuilt at some time, or due to the manual not matching what actually happened on the assembly line.
