Frequently Asked Questions
Can a linkage adjustment fix P0853?
Yes, if the shift linkage is out of adjustment, the range sensor may not correctly detect the Drive position. Adjusting the linkage is often a simple fix.
Will the car still move with P0853?
In many cases the transmission will still engage Drive mechanically, but the TCM may default to a safe shift strategy or limp mode because it cannot confirm Drive is selected.
Is the range sensor expensive to replace?
The sensor itself is typically $50 to $150. Labor depends on its location, with most being accessible from outside the transmission.
