The cheeek bone is connected to the toe bone...the toe bone is.....Whooops!!!!

The computer dictates the transmission shift points-- with new gears you're into a new data/speed curve: dont get the speedo corrected and you will be shifting at the wrong points.......

but x10000000000000 if you dont trust the guy-- DONT have him work on the jeep.

 

Your shift points aren't going to change related to speedo. It shifts because of RPM (tach) and load, not speed.

For axample, under a certain load, your tranny may shift at 4500RPM, regardless what size tires you have or what your speedo says.

 

Pretty sure he knew that, but people are just used to saying "have the speedometer corrected" from the older Jeeps, it doesn't directly correlate to the JK's, but people are kinda using it interchangeably

Having the "speedo corrected" on the JK's actually changes the parameters of the shifting curve in the computer as was mentioned earlier. It isn't a simple little gear change anymore. Gotta love the Nintendo generation . Telling the computer it has the correct tire size not only will display the correct MPH, but as a side effect also adjust the shift curve to match the new parameters. The computer takes rpm, load, tire size (which directly affects rpm and load) etc. into consideration when adjusting the shift curve and therefor, to a degree displaying speed.

That is, to the best of my understanding anyhow.

...Now where in the hell is my carburetor?

tomAto~tomOto.

 

I thought the man pedal on the left and your arm on the right decided shift points.

 

No "man" peddle in an auto.
