I've tried and failed to put a 40 tooth speedometer gear into my Atlas.
I'm going to try one of the inline electronic calibrators and was hoping some one has tried one of them.

 

I had the internal speedometer gear in the transmission on a Subaru go bad, so I got a Dakota Digital Speedo Computer and tapped it into the Antilock Brake sensor off the wheel hub to grab a pulse for the speedometer, worked great.

I believe this was the one - http://www.dakotadigital.com/index.c...rod/prd126.htm

What is your question?

 

Thanks.

 

I used the same when I rebuilt my Camaro. For the Jeep, GPS tells me I'm going about 3-5mph over what the speedo is saying so I'm good with that. :-)

 

I'm reading 68 mph when I'm doing 55. One thing nice is I can set the cruise control to the lowest setting which is 35 mph and still drive on my country curvy road. 35 is like 27 or something.
