You've got three options, I've only used one.

1.) Use the front wheel sensor as your vss reference, I've used this and it worked fine, only no more abs
2.) Dakota digital makes a pulse generator that mech connects to the th350 speedo gear and then wires to the vehicle vss input.
3.) Spend the $$$ on a new tailshaft housing

 

Well at the stage that my trucks in anyways I could give 2 ***** less on having abs haha. Do I have to remove any abs modules or anything after this. ?

Next do u have a link to option number 2 for the sensor conversion oFf tha tranny
?

 

I think I'm going to keep my ABS and just order the tailhousing from rossler. It might look factory

 

cut/connect the wires for one of the front wheel speed sensors, then connect them to the two wires for the trans speed sensor. You can't leave the front speed sensor connected to its original pcm connections. Then you'll have to go into the speedometer tables and play with the pulse counts until the speedometer is accurately displayed.

 

from what i was told the 4l80e is a th400 but with OD

 

Yes n no i dont know the whole details but they are similar such as in my 400 im using a 4l80 hub unit for internals since its a bit better due to design. but im no tranny expert jus know what my builder n i discussed so far...

everything is still up in the air for me but using that sensor how would i dissable the abs completely in the computers..

 

By disabling the input, the ABS is defaulted into "stupid/wait" mode and is thereby nonoperational. Once the front sensor is reconnected to the computer, then abs will resume operation.
