New 4.56 gears installed and now traction control problems

Just had a set of 4.56 gears installed on my '08 f-350 srw and now the traction control is kicking in randomly. I'm assuming the speedo has to be recalibrated for the gears??? Just looking for some answers. thanks

Wrong. The ABS tone ring on the rear axle that the speedometer is read from is located on the carrier, so gear ratio does not affect the speedometer, only tire size does.

I guess i don't see the difference, if it has a lower gear the axle will spin faster at a given rpm just like if you had a short tire.

The speed is measure after the differential, on the carrier, not at the transmission like they used to. So, gear ratio does not affect the speedometer, but tire size does. I realize I pretty much just said the same thing, so I guess I can't pit it any simpler.

it measures axle shaft/carrier speed. which does not change with gears. the transmission shifts with mph. so if nothing was re-calibrated, the truck is running more rpms then the tcm is use to, its probably shifting too late and hitting the rev limiter.

Check for ABS codes. If the rear tone ring wasn't installed correctly or the speed sensor is dirty, it can cause false readings and mess with ABS and traction control.

No ABS lights or any alkward shifting. If i leave the traction control on then sometimes it kicks on. If I just leave it off theres no problem, runs fine. I will say though these 4.56's are sweet!
