Recently picked up a 1999 V70 XC. All was good for about 300 miles. Pulled out of a driveway and the flashing trans arrow and check engine light went on. Had my regular car shop check it out and they referred me to a transmission shop. To make a long story short,the trans shop has checked out the wiring from trans to TCM and all seems OK. Before switching out the TCM and reinstalling the harness verification of solenoid resistance is needed. So far he is coming up with:
SL at 11.8/11.9, S1 at 13.4 , S2 at 13.7 , and STHG at 3.4 . He does not know what the STHG designation is. The transmission is a AW 50 42 LE . Any input on the solenoid resistance specs and what the STHG is would be greatly appreciated.
