PTU Leaks From the LH Side
WARNING: This page is about a different variant/trim than selected.
If the leak is the red automatic transmission fluid, the compression seal needs replacement. This is between the PTU and transmission. Refer to POWER TRANSFER UNIT (PTU) in the Removal portion.
If the leak is brown/black and venting fluid from the top of the PTU, the PTU is overfilled due to the input shaft seals leaking red automatic transmission fluid into the PTU. Replace the input shaft seals, refer to INPUT SHAFT SEAL .
