Been having code P1898 from my 97 sofar I've replaced solenoids, ss, swapped tcm out and nothing. Did a check with voltage meter and I'm getting no readings at all. Going to test once more with different meter but I'm thinking I should replace both internal and external harnesses and wonder if anyone has one on a part out

 

Im gonna be parting out a 1991 aw4. Would it work?

 

no the 97 is abit of a problem child. Re did tests this morning with better multi meter and everything checks out. gonna be searching for a transmission possibly

 

where are u located? I got s transmission from a 99
