Hello - new to the forum. I've worked on a few Rangers and B's in the past but never owned one. Been a mech for about 15-20 years now, but my expertise is 50s-70s (mainly GM, sorry).
I just picked up a 96 xlt in decent shape and I've had an issue with the speedometer accuracy since I drove it home.
I have replaced the VSS twice now, and replace the connector as well. The plastic gear is perfect. Watching live data on my scanner I can see an accurate reading from the VSS, but the speedometer is about 10 mph off, when it isn't sticking.
(No codes, no flashing O/D, etc).
Two questions:
1.) should I just replace the speedo head and check the grounds along the way?
and...
2.) could this cause rough shifting? The 4r44e is both electronically controlled and fluid pressure controlled, correct?
Separate from the speedometer issue, I have replaced the #1 shift solenoid, the tcc solenoid, tightened the valve body to factory torque, fluid/filter change with fresh mercon v and a bottle of lubegard mercon v additive and adjusted both bands (appeared to have never been done).
I've done a lot of other maintenance to this so far that appeared to have never been done. U-joints, brakes, IAC, fuel pump, etc etc.
