Have you calibrated your speedometer?

[sharpxmen]

like he ^ said
mine was doing it all the time, fixed the speedo gear and never seen it again.

Isn't there a sensor that tells the ecu you are in 5th so the light doesn't come on?

[sharpxmen]

nope, no sensor, what i can tell you is before i had the R&P replaced the light was coming on all the time, once the speedo was accurate didn't see it come on.

cool thanks for the fast responses ill get it calibrated or is that something that could be done by changing a part?

[sharpxmen]

it all depends of your axle ratio and tire size, you can get pretty close matching t-case speedo gear once you calculate by how much is off.
or you can get a dakota digital speedo calibrator, it goes on the signal wire from the sensor and you can increase/decrease the setting to match your actual speed.

I like the little calibrator motorcycles use. (One of the members has one)  It's tiny and easy to use.  Though I've been doing the gear thing since forever.

I've had great luck with my Dakota Digital...but I needed one since my Jeep hasn't had a speedo gear since almost a year after I bought it.  It sits just inside my door sill so I can reach down while driving to adjust it if necessary.

I just took out the light bulb for that light...  It's absolutely worthless to me!
