Question about 2003 Dodge Neon
It has hard upshifting and slipping. It is especially bad when it is cold. Runs much smoother when the weather is hot. Sometimes I have to get it to 3000-4000RPM before it will shift. Most of the time it will get stuck and wont upshift at all, but will stop slipping, but if I turn the car off and on again, it will upshift again. No problems downshifting
tork converter lock up switch is sticking change oil and put in some lucas transmisson condtioner and change the filter two.

have you dropped the pan to see whats the bands are set at, any debris in pan bottom, whats your governor pressure, if bands are ok, but gov pressures are not relative to speed 1 psi per mph up to 95-127psi, port is on pass side of case rear top right, scan tool would be very helpful, your must have mil light on for this problem, gov dtc's, replace gov transducer as gov solniod as a pair, no exceptions, also are there any 02 sensor dtc's, shorted to voltage, this wil make pcm do stupid things to trans shift, affecting gov signals. GOOD LUCK RDJRP

Cheapest thing to try is a fluid flush and filter change. Unfortunately, if that does not work, then next bet is probably a rebuild.

Testimonial: "thank you so much! I wil try and hopefull will work. "
there is no up shift sensor or down shift sensor,
there is a output sensor,input sensor,speed sensor,
you need to have your TCM checked to see which of these are at fault.

The absence of 3rd and 4th is imposed by the transmission computer as a precautionary measure. The system has detected fault and rather than risk doing any greater damage has provided a limp home service. It needs to have a transmission specialist look it over and read the error codes. How do your transmission fluid levels look?
