I have 2002 maxima gle 163000 miles the transmission is shifting hard in 1st to.2nd 2nd to 3rd it shifts with a little slipage a couple hundred rpms other gears are fine. Recently did a transmission flush dropped the pan and cleaned it out it felt like it helped at first but I beleive its about the same now. It feels sluggish when I accelate while im already driving and it has delayed shifts while driving slow. When I am coming to a stop I can feel the gears downshifting
Please help any ideas will be great

 

In my experience, all of my Nissan's (92, 97, 02, 03) and Infiniti (97) responded well to using Lucas Oil Trans fix along with regular drain and fills. Annually, I drain and fill the transmission fluid through the drain plug on the bottom of the pan. I usually run through 3-4 gallons of Valvoline High Mileage Synthetic transmission fluid (please note that this means draining and filling 3-4 times , as the car holds approximately 9 quarts of fluid, but only a shade over 4 quarts comes out through the drain plug), and on the last fill, I mix in 1 24 oz bottle of Lucas Oil Trans Fix to the fluid. Be sure to account for the additional 24 oz of Lucas Oil when adding the trans fluid on the last fill, and definitely check your fluid level with the car fully warmed up after your done. You do not want to overfill or underfill. This combo mixture has kept all my cars running after the first sign of slippage. Please note not to use Autozone or Castrol generic tranny fluid. It doesn't work well in our cars! Always use high quality fluids!

 

i used the best amsoil tranny fluid with.half bottle of lucas I will do another flush with a full bottle of lucas do you think it could be shift solenoids or transmission speed sensor they are rather expensive so hate to put parts on that are not the cause of it.

 

Could be the shift solenoids. There was a TSB for 5th gens but not 5.5 gens, IIRC.

 

Are your engine and tranny mounts in good condition? Bad mounts can cause hard shifting also, and also check to see if your Axle nuts are tight on both wheels. I think it is a size 32mm.
