4x4 Speedo Cable Std. to Auto Question? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Ironhorse** · 09-13-2012, 06:13 PM

Should have asked this in my previous transfer case bracket question but didn't think about it then. It would seem my speedo cable from my current
sm465 standard transmission will not work with the TH350 4x4 auto that is going in. The speedo cable mounts to the left side and the auto trans. has the speedo connection on the right hand side? Current cable is to short to make the connection. Anyone have some thoughts on this to help?

You can by longer cables they make a few different lenghts in them.

Forgot I had one as I have never ordered from them but I did look in an old LMC catalog I have and apparently they have them in 63,80,83,100 & 120 inches in length. Catalog I have is a 2006 edition but that may be the way to go. Will check with some board venders here first before ordering from LMC. Rather support venders who support the board. Thanks for the reply.

The speedometers cable goes to the output rear housing on the tcase. You can swap just the rear output from the 10 spline 205 to the 27 spline no issues. Just different speedometer cable input.
