IM NOT RESPONSIBLE FOR ANY DAMAGE U DO TO YOUR CAR !!
OK I know this is old, but its help me alot so i want to help anyone who is having the same problem...
my 01 maxima was slipping and change gears very un-normal
I went to the Nissan dealership and they told me that my transmission control module "TCM" was bad.
They charge me $120 to look at the car.
They also told me it was going to be $1200 to replace this part !!
no one so i called around and I found the part for only $120 Dollars at the local used auto parts store.
the part number is 31036 4y901 It has a big C1 up top. but this is only for 01 Maxima !!
This are the pics your would not have some many cables i have a gps with amps this is why i have some many cables....
this part is very easy to remove if you have some what knowlodge about cars. its located right under the Car Stereo
all you need is a flat screw driver and a phillips... BEFORE YOU TAKE OUT THIS PART MAKE SURE U DISCONNECT THE BATTERY
use the flat screw driver to pop the middle console.. then just work ur way up dont break anything everything pops off and its about 10 screws total...
the tcm is under a black little box. u take of the 2 screws and both boxes should come out...
disconnect the old box put the new one in and put everything back together.
once your done. plug the batt back and that should it....
I drove the car around my house and it deff felt like it was shifting a lot smoother. i havent taken it for a long drive to see if its really the cause of the issue which i hope it was......... I well post once i take the drive.....
I hope this info helps some one in need...
