700r4 wiring questions
I picked up a 700R4 from an 88 Astro. It was rebuilt just before the van was written off and I got it really cheap. I understand some of the internal components are weaker than some models but it's going behind a stock 305 and it's not going to be raced. It's going into a 57 truck restomod project. I've gathered some good info and I learned a lot about the principles of TV adjustment when I put an AOD in my Ford but I'm confused about the electrical connections that are necessary for the plug on the 700r4 tranny. Do I need to wire it up to a switch and/or the brake light switch to lock/unlock the torque converter as some people have been suggesting? What is the purpose of locking the torque converter manually? Doesn't it lock and unlock automatically during normal driving? Does the 700r4 have a neutral safety switch in the tranny like the AOD or do I need to rig something else up?

I emailed you a response since this appears to be the same question emailed to me today

nope, since this person does not understand what controls the converter clutch lock-up between an OE vehicle and an aftermarket application like the 57 chev truck. I am sure there are many more questions he has about this. Hopefully we can help and not confuse... LOL

Hey thanks fellas and yes, you are right, I do have more questions. I'm afraid wiring is my achilles heal. I like those diagrams at the Bowtie Overdrives site. Fairly easy to understand. Here's my questions:
1. the fuse, how many amps? 15? 2. 87a goes to the A pin on the tranny (front outer position) right? 3. 85 goes to 12v at the brake light switch right? ie. 12v when the brakes are applied. 4. If towing I should have a switch to lock the torque converter to avoid overheating right? 5. the switch goes on 87a WITH the red wire right? 6. the other side of the switch goes to the ground position on the plug (D) or rear outer postion, right? 7. can I use a lighted switch? By the way I pull the pan off and my pressure switches are dark grey (not silver). Does that make any difference? |
