| I do not think you would have slippage if it was the rear. It would have the same issues in forward and reverse. I would check the fluid level in the trans and see if it is low. Does the truck act like that in drive?? If it does there may be torque converter issues. I would also take it back to the dealer and tell them there is something wrong. Did they give you a warranty on the new tranny??
