Before i get into it...1998 Cherokee Classic / 4L I6 / AW4 / 170k / auto

So about a month ago i threw a CEL for a 2-3 shift solenoid which through searching ended up getting a great deal on 2 solenoids through a web site recommended by some forum members. About a week ago, i swapped in the 2 new solenoids and trans gasket/filter along with a new tensioner pulley and serp belt. Ran like new until this morning when it threw a CEL.

It ran through the gears perfect, but would not go into OD or TC lock up (im not sure which is the final drop in RPMs) for the 10 min drive to work. Left work, still had a CEL, but had OD this time. Ran the code when i got home....p0700 and p0705...

For the last 2 years it would VERY randomly not start in park and the reverse lights would not come on every now and again. For the last 2 months, it will not start in park once a week (starts fine in neutral) and the reverse lights dont work at all. With the code im obviously hoping its the NSS, but ill be wrenching on it this weekend so any other imput on things to look at would be greatly apprecitated.

Thanks in advance
Chris

 

After running the code and 10 miles of driving last night, CEL is off and running normal again. Should i definetely be pointing towards the NSS?

 

Pull, clean, reinstall the NSS.
