Automatic Transmission codes for Nissan Patrol 2005 (4.8 gasoline engine)

Question

My Nissan Patrol shows the following codes P1764, P1754, P0720 and P1772. It Clickes when i move tha transmission from P to R to N and D, and the transmission gets heavy while driving (doesnt speed with more fuel), but on other rimes it drive smoothly!.. What should my mechanic fix?

Answer 1

I would drain the fluid in a clean container and check for metal shavings or pieces of metal, (maybe remove the transmission pan and check the magnet they have inside that is suppose to catch the metal shavings

if there is a lot of metals or pieces the transmission might be bad. if it is normal I would just change the fluid with orginal Nissan fluid. if the problem comes back the the valve body might be bad.
