Which speed sensor?

I've just swapped in a 4x4 tranny and tcase into my 02 Prerunner Tacoma from what I think was a 97 4runner (It was def a 4runner but have forgotten which year it was for sure...) Edit: BTW, I've got the 3.4 V6 with the auto tranny.

Question is this: How do I figure out which VSS (speed sensor) to use since the 4runner tcase doesn't have one? (It has the spot, just has a cover bolted in it.)

At first, I thought just the same year Tacoma VSS as the 4runner tcase is from, but then after more reading, it sounds like the 96-97 4runners would take a mechanical style speed sensor in the tcase...

Here's some pics if it helps....

Have you popped that cover off and looked in there? I have a 4Runner 1999 year trans and TC in my truck and it has an electronic sensor. Perhaps your recently removed vss will fit in there.

 

So after making a thread on this on several sites, I didn't find any exact info on how to tell other than peak through the hole and count the teeth, which is a difficult task when the case is already on the truck... And which still didn't tell me whether or not mine took a mechanical one or an electric one, but in a few helpful threads, most seemed to think mine should take the electric one.

Soooo.... I made a crazy decision and just bought a random speed sensor on ebay. I found one marked as from a 98 4x4 4cyl A/T. It was marked as 11/32.

When I got it, first step was to see if it fit into the case--miraculously, it fit perfectly. Next step was to extend the wiring ~12 inches or so.

Once done and connected, I fired up the truck and took her for a spin and--Voila! I have a working speedo again!

Now just gotta figure out how close to actual speed it is getting me....

Thanks for all the help!
