Dave WM Posted April 30, 2018 Share #37 Posted April 30, 2018 hmm got me on that one, only one you need for the 5 speed would be the bottom pic right of the fill plug. Link to comment Share on other sites More sharing options...
CRS Posted April 30, 2018 Author Share #38 Posted April 30, 2018 I was surprised by the number of connectors too. So I only need the one with black wires next to the fill plug? Link to comment Share on other sites More sharing options...
Dave WM Posted April 30, 2018 Share #39 Posted April 30, 2018 (edited) yes. That connector has oil pressure, reverse light, AT inhibit and starter motor solenoid wire. The AT inhibit seems odd on a manual, can you start you car with the clutch in while its in gear or do you have to go to neutral, and do you have a "neutral" idiot light some where? seems odd since I have a 75 and my 4 speed did not have those switches. I did see a boss that was not machined on the trans that is to the left of the fill plug. With all the experts on this forum I am sure someone will chime in on what those are on your 4 speed.

Dave WM Posted April 30, 2018 Share #40 Posted April 30, 2018 (edited) seems there is a 4th gear switch out there as well as a neutral switch perhaps as some kind of lock out for safety when starting without the key. Think the 4th gear had to do with ign timing. Do you have a little box near the battery with a push button switch on it?

CRS Posted April 30, 2018 Author Share #41 Posted April 30, 2018 No lights that I noticed. It will start in neutral clutch up or down. Also started in gear clutch up or down. Thought I'd give it a try in gear since the car is in the air. There isn't any safety features. Link to comment Share on other sites More sharing options...
CRS Posted April 30, 2018 Author Share #42 Posted April 30, 2018 Also just checked the connector with the black wires and it's for the backup lights. Link to comment Share on other sites More sharing options...
Patcon Posted April 30, 2018 Share #43 Posted April 30, 2018 check the 2 wire switch for continuity with a meter in each of the gears. Link to comment Share on other sites More sharing options...
Zed Head Posted April 30, 2018 Share #44 Posted April 30, 2018 therz picters in the fsm. Seriously, they have really good pictures, with labels and stuff. Some of the ZX transmissions had a lot of switches. Hope you measured your throwout bearing collar and pressure plate height. Link to comment Share on other sites More sharing options...

I tried to get thru that section about the interlock and 4th gear, glad my CA car did not have it. Link to comment Share on other sites More sharing options...
CRS Posted April 30, 2018 Author Share #46 Posted April 30, 2018 For the clutch the part numbers for the 75 and 83 2+2 donor are the same. I should be fine. Just dropped the diff to replace with the 83 zx one that the 5 speed came from. It's a 3.90 ratio. Noticed my CV shafts have the flange with studs and the new ones don't. Do I need to take apart my old diff to move them over? Link to comment Share on other sites More sharing options...
Dave WM Posted April 30, 2018 Share #47 Posted April 30, 2018 nope the just pop in, retained with clips. a good yank and they should come out, just be careful not to damage the seals if you start prying on them to get loose. I would use two crow bars on opposite sides, pry against the flange and the diff, again watch out for damaging the seal area. putting them in just push in until clicks.

CRS Posted April 30, 2018 Author Share #48 Posted April 30, 2018 Thanks. They are now moved over. Time to move the pinion flange that the drive shaft mounts to. Mine is square the new one is round. Link to comment Share on other sites More sharing options...
