Transmission Switch Delete Plug

[DARIN 510]

Not sure how many know of this or how many even care. This plug is used to delete those extra switches that are no longer being used. I’ve gotten the factory plug

(32135-U020A)for my 280ZX 5 speed. You can buy these from this website. https://datnissparts.com/rwd-transmission-switch-delete-plugs-32135-u020a/
But what they have in stock is all that is left. It is NLA from Nissan. So I was curious what could be done once they are all gone. I had noticed that the thread pitch is M14x1.5 and found some oil drain plugs with the same threads.

And here is the the drain plug by Dorman. Part numbers are 090-033CD. The part number 090-075CD is the same thread length as the factory Nissan plug. The 090-033CD part is about 1 mm longer. Both should work

The transmission pictured is a dogleg. Why remove the switches in the first place?

Because there’s an extra switch that you don’t need or is not used. One is a reverse switch which you need the other is I don’t know. Some other transmissions have multiple switches that are not being used.

We don't use or need our appendix but it's easier to just leave it alone.

Hey Mike, news flash. Some guys like clean installs. No loose ends. If he doesn't need the switch, then it is cleaner to delete it.

Thanks for the legwork. I needed to delete a switch on my new A series trans, which is going in a race car.

Do the math on this.If you use a bigger  drain plug.Does that mean it takes up more room in the Transmission,so you need less fluid.lol.One way to look at it.But it does,rightSo is it better to use the smaller plug.Just asking for a friend..

Splitting hairs much?

[gm510]

anyone happen to know the part # for the reverse switch for that transmission (63a) 

[datzenmike]

For the 63A shown?

 

Reverse light switch.... 32005-K1000 also used on all 4 and 5 speed 71B transmissions.

[gm510]

thanks Mike, yeah i’ve got the same box needs a new switch 

[datzenmike]

All z/zx cars, 810/Maxima, all 620s after '73, B-210 and A10 5 speeds, all 720s, all S110 200sx and all S12 200sx to '86. Very common switch.

[gm510]

yeah right, should be easy to find then, cheers 

[gm510]

so the switch that’s been replaced with a bolt/plug in above photos, is that the reverse switch in this transmission ?

EDIT

all good found it, bottom one is reverse

No the upper one is the reverse switch on this one. This is a dog leg transmission in the picture. I am only into illustrating a delete plug for extra switches that are not needed. disregard the reverse switch part I had my switches mixed up. I am deleting the neutral safety switch.I think that’s what was there. It’s going into a 510 so there is no wires for it.

Ah, but for the race car guys, which weighs more, the switch or the plug?
