I know the power divider / auxiliary 3 speed for the tandems was offered in TF trucks. How about dealer options?

And the problem with someone installing something like that its not always done correctly. Just wondering if dealers ever offered such things. The particular truck is supposed to have a 4 speed. When the fellow mentioned a spliter I asked if he meant a 2 speed rear axle, nope its a transmission behind the 4 speed. Just wondering what kind of scabbed up mess it all is.

That section is really for speedometer adapters but list some of those for use with model 6231 and 8031 auxiliary transmissions.
I don't know what that says for the auxiliary being factory installed or not. | | | | | Joined: Jun 2011 Posts: 5,096 Crusing in the Passing Lane | | Crusing in the Passing Lane Joined: Jun 2011 Posts: 5,096 | I have also removed aux. trans like Grigg has, they all looked professionally done, they are listed is service manuals in many GM trucks.
