Swapping TH400 In -- Want Speedo To Read
Ok to start off my car was originally a 2.8l / 5 Spd car. I am now in the process of swapping in a 400 SBC and TH400. Before I had the 120 MPH V6 Cluster, but I have switched to the 140 MPH GTA V8 cluster.
My question is what all do I need to buy to get the speedo to read correctly for my TH400 Tranny?

Cluster is out of what year vehicle? BTW, check the tech section on this site. There's a great How To article that addresses Trans Am electronic cluster swap. Even has wiring id to boot. Very helpful if that's what your working with?

Re: Swapping TH400 In -- Want Speedo To Read
Not sure what year GTA the cluster is out of, but I already have it in my car. Ill check the Tech Section, but Im looking more for how I get my TH400 (Which is I believe set up for a cable speedo) to work with an Electric Speedo like our cars have. I know I need an adapter, but I was hoping someone had a part number of one that would work, and if there is anything else besides the adapter Ill need.
