2009 Aftermarket Limited Slip and Traction Control
A year or so ago I added a Detroit Truetrac Limited Slip differential with Richmond 4.10 gears (tried 4.56, would not fit) on my 2009 Dodge Ram 1500 Sport 2WD. It was equipped with 3.55 gears and an open differential. Everything is fine (save a slight gear whine) except the traction control no longer functions as intended. The IP indicator will flash when the wheels are spinning but you can roast the tires and there is no attempt by the PCM to interfere to mitigate the slippage. I have asked the dealer if there was a software flash or an option to enable in the Starscan to tell the truck it is now equipped with a Limited Slip differential. Of course they looked at me like I had two heads! I explained that it was an option from the factory. Claimed it couldn't be done aftermarket.
My question is how to get some semblance of traction control back? It will break the tires loose on a wet road North of 60 MPH! Thanks in advance for any insight anyone might have.
