VX Transmission expert needed

[Todd O]

I have a 92 civic VX 5 speed manual transmission. I recently replaced the transmission. For some strange reason the shift light comes on in 5th gear, like I have a 6th.

I have looked at the manual and am unable to find any kind of switch that tells the car it is in 5th gear. I know if did not do this before.

Any ideas what tells it not to display the shift light?

I can't remember ever seeing any switches on the transmission in any 90s honda other than the reverse light switch assembly. Are your reverse lights functioning? It may be that the same switch that tells the reverse lights to come on has a dual funtion that tells the ECU it's in 5th. But that's just dumb speculation. The work I've done is probably 90% domestic cars.

That is the only switch that I saw too and the reverse lights do work. It seems like the speedometer has a lot of wires going to it. I just could not find anything in the manal about it.

Thanks for the attemp.

I know that my '83 civic has a duel function switch, it confused me at first, but it has an extra wire coming off it, and it's something like half way pushed in tells it that it's in 5th, I would dubble check the switch, and also make sure you got the right tranny, becaus if it's wrong it wouldn't have the little rod to push the switch.
so how fast is yoru engine going at 65mph?

The upshift indicator on the VX does not use a switch - it uses the inputs from the ignitor (engine RPM) and the VSS (wheel RPM) into the ECU to determine which gear you are using. It then determines when the upshift indicator comes on. All this is done internal of the ECU. I want to say that my upshift indicator came on on my VX in 5th too - I can't be too sure though, because when I owned it, I paid no attention to it.

I don't use it either. It is just one of those things that bugs you.

Before I replaced the transmission it did not come on.

AT 60 It is about 2600 RPM. My millage seems fine. I get around 47 MPG average.

I will take a look at the reverse switch again. I did leave the one that came with the transmission on and did not use mine so I will look at both of them.

[GasSavers_Ryland]

I would guess that you have the wrong tranny, at 65mph, it should be around 2,100 rpm

Checked out the reverse switch on old transmission and it only makes contact when in reverse. Must be someplace else that tells it that it is in 5th gear.
