pinion reset

Is the pinion reset really worth the money. The jeep dealership next to me said it can be done for 131$. What are you really getting out of this?

Basically resets the computer for the correct tire size and lets the speedo read correctly.

$131 My dealer did it no charge. eek2dance.gif

Does it correct the shift points, help mileage back or anything like that. Looks like I have to look for a new dealer to do this. What is needed to perform this?

I've had my BCM reprogrammed for larger tires while I had it in the dealership for an oil change and I don't remember it costing me an additional $130.

You need the dealerships computer to talk to your computer - shouldn't take more than a few minutes - but depending on the dealership - it's been anywhere from free to 1 hour labor charge.
(and I have 2 dealerships that say it can't be done)

Man, that *****, mine did mine for free during a regular service.

waste of time
not to mention the money
all it does is make the speedo correct
big effing deal
I have a GPS it tells me that my speedo is off by X %
great it is 5 mph off at 60 ,going 65 when it says 60 problem solved
best part is in an hour I go 65 miles but the odometer shows 60
figure it has been that way for the past 35K so I really put over 38K on it
factor that in and it is past the 7/70 when I got my CV shaft replaced under warranty

good thing I do not worry about the little things

Mine speedo was off before. Got pulled over doing 69 in a 55, speedo said that I was 73. I havent checked it but with the larger tires it feels right on now.

Besides speedo it should also correct your mileage reading because the mileage and speed is both based on the same speed sensor.

A pinion reset does correct the speedo,but that is just 1 of the things it corrects.The biggest is the transmission shift points,just by doing the reset it feels almost like you geared lower since now the transmission now shifts correctly,plus this relieves alot of stress off the transmission also which will make it last longer.Before adding the bigger tires your trans uses 3 speed sensors,2 mounted on the trans and the rear diff sensor,to determine shift points(along with other sensors) and as soon as you put on larger tires your TCM goes screwy for awhile and adding stress on the trans from incorrect shifting.Yes after some time the TCM will "learn" the new pateern but when compared to it's defualt settings it is making the trans shift werid and wrong which leads to early trans failure.
