Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hey there thanks for the question.
This is an indication that the TCM inside the transmission is shorted out and will need replaced. I have seen this quite a bit on the frontiers and pathfinders from 2005-2010. Mainly due to the fact that they are prone to the radiator failures that cause cross contamination with the transcooler at the bottom of it. When this happens moisture and coolant get into the transmission and damage the TCM.
If the car previously had cross contamination issues then this was likely the cause. If no previous contamination on record this would be a good time to inspect the radiator for the pink froth on the lid that's generally associated with teh contamination.
If you have further questions just ask and ill be happy to help. If not please leave a kind rating. Thanks.
