02 wrangler transfer case...

Where the heck do I yank the speedo gear out from? It doesn't look like most of the transfer cases in the videos and guides

Sorry for the bump just an hour later, but I'm in a bind. Anyone have an idea of where the speedo gear is? I know I am looking for it on the back of the transfer case, but it simply does not exist (or I'm not seeing it)...

You have a JB Conversions super short SYE, which means you no longer have a speedo gear, it's electronic pickup.

Is there any way to adjust it? My speedo is WAYYYYY off.

Edit: I've got 4.80 gears and 35" tires.

I use the speed o healer. It lets you adjust it anytime you want, and it's completely plug and play. Blue Monkey Motorsports, Inc. : : : : HealTech Electronics SpeedoHealer (R): Product Overview

Yes, you just unplug that connector at the transfer case, and the speedohealer comes with matching plugs that plug between them. Then you can either mount the little unit in your engine compartment or cab and program it to whatever your speedo is off, and it magically fixes it. Really really easy. Nice thing about it is you can dial it in exactly and if you ever change tire size or regear, just reprogram it.

At least you've got a really good slip yoke eliminator in the JB.

How do you tell how far off you are? Or does the computer automatically do it?

IIRC, you drive it at a certain speed by the speedo (60 comes to mind) and check how far it's off at that speed by GPS or someone next you, then they give you a chart that gives you a number to enter. It's something similar to that...it's been awhile. I know that it's real easy and you can adjust down to the mph. It comes with the instructions on how to do it.

Out of curiosity - and I haven't seen a definitive answer elsewhere - would having an improper speedo cause my rig to shift at the wrong times, or impact anything related to fuel injection?

If this was a horribly stupid question, please go easy on me. :P

Hey Water Dog, I went with the speedo healer and it works like a champ! I love having an accurate speedometer. At 60, my speedo was showing 68. So yeah, I was a bit off.

Hey mods - please feel free to rename this thread how you see fit. I realize that it was a bit misleading. I need to do a better job at naming my threads.
