QR Code Link to This Post
B&M torque converter lockup controller.
Works with all GM automatic transmissions (and maybe others) using a lockup style torque converter and a mechanical speedometer. GM TH-700R4, 200, 200-4R, 350 and 4L60.
Comes with everything included with a brand new one, except the instructions. You can download the instructions from the B&M/Holley website and you probably should before you buy. Installation is quite easy, but you should review the instructions first.
Your transmission will need to be wired internally per one of the 3 diagrams provided in this post:
1 wire = internally grounded
2 wire = externally grounded
3 wire = externally grounded in series with 3rd or 4th gear pressure switch
or as shown in the B&M instructions. Supplied connector is 2 wire and will work with all 3 scenarios. Most of these transmissions are wired in one of these ways.
Seller not responsible for determining how your transmission is wired. Make sure before buying, NO RETURNS.
This controller works perfectly, exactly as advertised. I am selling because I wanted greater functionality, similar to how the factory set them up with various time delays. So I designed my own system. If you are interested in a more advanced control scenario, for just a little more money, contact me.
NOTE: I had to cut the signal generator wire because the connector would not fit through my firewall (see photo), and to remove it later for my new setup. Just cut the cable to length and solder the wires back together.
These go for around $350 online.
