Possible to adapt the Chevy VSS to run Jeep speedo?
I'm in the planning stages of a tbi350/4l60e swap. At the moment I am trying to decide how I want to handle the transfer case.
As I see it, there are several options:
1. Run the np241 that I have with this combo (1993 Z71 truck). I can get the super short sye and keep the overall length down to a reasonable level. The only problem so far is that I am unable to find information on getting the Jeep speedo to work off of the Chevy VSS since they do not use compatible signals. For me to go this route, I'd have to be able to buy an adapter to make the factory speedo work. I'd rather not have to spend money on all new gauges.
2. Use the front case half from an NP231/233c and adapt my np231j to the 4l60e. This would retain my Jeep vss and allow my speedo to work. To keep the chevy pcm happy, I'd have to add a reluctor ring and sensor to the tail of the 4l60e. Cost for this is $60 for a 233c from the local "pull it yourself" boneyard and ~$100 for the vss/reluctor ring kit. I'll probably still need an sye kit due to the length of the engine/tranny/tc combo. This is currently my likely choice unless someone has a better idea.
3. Buy the adapter kit from Novak/Advance to make my 231j fit the 4l60e. This is kind of like option 2 except it's more expensive. $500+ for the kit. And again, I will likely need a sye anyway due to length.
So does anyone know of a way to make the Jeep speedo work with the chevy vss? Anyone see a better idea than what I mentioned above?
