Hey! I had my unit throw a P1870. And no overdrive... Put a new TPS-helped alot-but as the SES lamp is now off-and I really didn't feel it shift into O/D after the test drive,the RPM's are lower and there is still full converter lock-up. So does this look like the EPC solonoid? 97 4.3 4x4 161K Serviced trans @ 155K-had a good look inside,that solonoid is
easily R&R'd with just a pan drop,Right? Any input? Thanks! step66
