2000 ply. neon wont shift into overdrive been told it was a sensor whats it called and where is it located

SOURCE: 1995 jeep laredo overdrive is not shifting

Your overdrive should kick in at about 45mph, pretty much at or about 2000rpm. To see if it engaged, lightly touch the brake pedal and it will disengage.It should also disengage when you mash the pedal down to go into passing gear, and re-engage when conditions "normalize" again. You can tell that it has engaged because the tach will drop a few hundred rpms. If it's not doing this, a simple trans oil change (with filter) may correct the problem. OD is activated by a shift solenoid on the valve body that may be a bit gummed up.
95's show a shift control module on some diagrams I've seen, but not on others. I read this as a possible "half-year change" So you may or not have one. If you do, I'd check that as well!

some of the trannys has straps in them that sometimes needs to be tightened and that could be the cause of it

SOURCE: transmission does not shift to overdrive

yes, it has an input and output sensor and either one can cause improper shifting

SOURCE: i did a diagnostic test on my 2000 Plymouth neon

"Timing Belt Skipped One Tooth or More" To fix this I would recommend replacing the timing belt as soon as possible.
