Gen 3 tranny speedometer conversion mechanical to electrical

Postby k_trac » Tue Apr 05, 2005 9:13 pm

Im putting a ST205 engine / tranny into my 185. I need to know what I have to do to get my mechanical speedometer to work. I still have my mechanical sensor, and it doesnt look anything like the electrical one. I also do have the ST205 cluster, dont know if that would work, or if Id even want to use it. I know some other people have used the 205 tranny before.

Are the 92 or 93 cluster electrical? Mines a 90....

Any help would be apreciated.
Thank you!

Check gt4oc.com and the gt4 yahoo groups. I will have to do this myself. There is a simple conversion to do, but I am not sure what it is.

Good luck, and keep us posted.

As I PM'd you, I removed the whole 205 speedo assembly from the tranny and put the 185 in it's place. I think it's held down to the tranny with one (12mm socket) bolt.

Ya, easy as pie this!!!!!

These are the two sensors, obviously, the one with all the gear is the electrical one. I dont have the 185 tranny anymore, so I dont know if there is something that I forgot to take off when it went.

There is another part to the 185 speedo that actually goes into the tranny and houses the gear and gear shaft to hook up to the part in the picture. It should be a direct replacement for the ST205 peice. If memory serves it was not too expensive when I replaced mine (my gear was worn out)

Wow, this is an old post, but still subscribed. I sold that car like 4 years ago.

Anyhow, I do still remember this.....there is a peice missing that I left on the 185 tranny and didnt realize it. It was just a drive gear that threaded into the trans. Im pretty sure I sourced one from a 184 in the junkyard, easy fix.
