Title: WTB: TH440 Fiero compatible governor assembly
Post by: WV Mike on May 28, 2015, 11:28:11 am

I got my Fiero back today from the shop with the TH440 transmission in it. My speedometer is not working because I need a Fiero compatible governor assembly for the TH440. Going to try to find one locally; however, I'm reaching out to the Fiero community for help.

Here is a link with information on the swap and what I need:

From the article, it sounds like you need a governor from a Fiero tranny that has the same final drive ratio as your TH440.

From my understanding, I need the governor, housing, and sensor. The one in the 4T60 (TH440) is the magnetic setup, which won't work.

I may have found the parts. If they are right, I'll post part numbers and where I got them from should anyone else go through this.

I received the governor assembly and put it quickly onto my transmission tonight. I was glad to see the part fit. I ordered the parts from http://www.txchange.com (http://www.txchange.com). I paid $40 for the parts and $14.72 for UPS shipping to South Carolina. Their part number for the governor assembly is RK84410.

Does your speedometer work with the new part?

Yes, the speedometer is working. I just have to use my GPS to see how much off it might be.

Does it shift at the proper RPM?

I'm thinking that you can use your original VSS gear, and the speedo will be correct. Or as correct as it was.
I could be mistaken, however.

What is the proper RPM for it to shift at?

With a V6, foot to the floor, the 125 will shift at about 5500. Maybe a little higher.
