I have not taken the time to verify each one for accuracy. Jackson who built this transmission for me back in 'o3 warned me that using freewheel as a passing gear is hard on a set of particularly small needle bearings somewhere, so I'm not in the habit of using it that way anyhow. Additional connectors and instructions are provided to use the original 1955-56 and 1957 ignition switches, original style door jamb switches, and overhead dome light. You dont really need any harness and if you did you could build it. Thats why I was asking for help locating parts to fix it. I strongly suggest you listen to people who have hands-on experience, not just a good internet search engine.
The kick down switch is on Ebay all the time. Parts are still available you just have to root them out. It literally makes no sense. What needs to be done?? Well at least I could before the planetary set came apart!! I just use the official wiring diagram and move on. I got your E-mail on this tranny.
Not cheap either but at least you will have parts guaranteed to work. We installed the 235 six without the transmission attached. Each wire is cut to the exact length required and wiring terminals are crimped-on just like the originals. He constantly complains about it. These Diagrams are easier to read once they are printed. This reproduction harness starts with the correct gauge wire, color-coded to match the factory wiring diagram.
Even so, we removed all the support structure between the fenders rather than trying to shoe horn it in and bang it against the firewall. I installed it with one wire from a switch to the solenoid. I ground the governor because I only run the overdive on the highway and interstate, and that's where I spend most of my time. If you have any Pre- 1960 Chevrolet Diagrams not listed here and would like to Share them, please send to Please Note that some of these drawings and schematics may be duplicated with a different file name in this listing. That had me thinking Chevrolet wired it so the governor will always energize the solenoid in both freewheel and direct drive without a manual switch to prevent it. I put an o'd trans in a 1954 Chevy pickup, it was fantastic! Ford used an electric switch at the accelerator pedal, and Chev used a bracket at the Carb mounted so that the accelerator linkage hit the switch at the top of its movement.
Jerry I have a friend that is really wiring his wrong then, because if he don't flip that switch before pulling out of the garage, it's over. Special terminals included for original. Now I want to incorporate the governor and it is working. Headlight, ignition and dimmer switches included. Do it, you will love it for sure. If you need the tel no. The factory way has a solenoid--governor-relay mounted on firewall--and a kick down switch under the acellerator prdal and a T handle cable under dash--Most can be bought on ebag--hope this helps.
If specifications call for it, the terminals are also dip soldered to limit resistance voltage loss. If you put it in reverse just once without locking it out first, you will have major damage. I used a bosch relay inside the old relay housing. I cruise at 75mph easily only turning about 1900 rpm. The switch they sell can be used in either the Chev configuration or the Ford one.
Power circuits are fusible link protected. Bracket for overdrive lockout cable The terminals on the relay that came with the transmission were labelled different than the original item, so that caused a little head scratching. . License plate connectors and terminals included. What has caused this confusion for me is a 1957 Chevrolet manual never mentioned this switch, just shove her down into overdrive and go. It's a great little transmission.
This Classic Update wiring harness from American Autowire allows you to plug into the original gauges and dash accessories, headlights, taillights and heater controls. It is easiest to just put it under the accelerator pedal, but making a bracket for the Carb mounted one is not that hard. If a new key and tumbler are needed, they are available from the manufacturer. Thanks again for all the knowledge, I love this site , Ed Ed, If you have a T85N, it is the identical length as your original trans. Copyright © 2000-2009 Jelsoft Enterprises Limited.
That solenoid shouldn't be pulling juice for nothing during those times when you don't need it. I don't use a harness, just a toggle switch. I have run across several at swap meets, but have not bought one because I can't find anyplace that has parts for them, nor can I find anyone to work on them! Oh yeah, mines a Chevy, there's Packard and Plymouth above, the overdrives are all Borg-Warner. It's worked great for 13 years so far wired wrong, but after driving my '50 Studebaker working as Borg Warner designed it, I'm motivated to incorporate the relay and governor unit, but don't have much use for a working kickdown switch. I referred back to the schematics in my '65 Motors manual, and they show no manual dash switch like the Borg Warner schematic does.
I'd suggest that you use a premade wire harness to save the wireing headaches. Easy to wire yourself if you want to. It was pretty straightforward, but our kickdown switch location under the gas pedal on the engine side of the firewall was a tight squeeze. Eckler's Classic Chevy offers the best in reproduction wiring harnesses for your 1956 Classic Chevy. I have 35 inch tires on my 57 chevy and a 3. Any help sorting myself out would be appreciated.
