My '93 Ranger v6, automatic seems to shifting back and forth, runs kind of
jerky. Doesn't seem like an engine miss, more like changing gears. Maybe
electric clutch coming in and out?
Leaning toward throttle position sensor. Got a pass on code readout tho'.
Thanks for any help.

Does it do it in D position as well as OD?

Do a search in this group on google groups
alt.autos.ford

Could be the VSS, how does the cruise control work?

I'll have to try in OD, the cruise drops out when it does it.
I was referring to the torque converter clutch. Don't know exactly how it
works, think it kicks in and makes a direct drive. What is VSS?  Thanks, HP

Sorry for not getting back, surprised no-one else helped... sounds like the
VSS to me...OR possible the MLPS which tells the PCM (computer) what gear
the trans thinks it's in.

The VSS is the sensor at end of speedo cable on the tran tailshaft.  Could
also be wiring from same.
