Question edited for clarity.
Question moved to model category.

When the CEL comes on, you need to read the code. The code tells the problem and searching that code give the solution to fix.

The hesitation of your 2006 PT Cruiser when putting it in reverse may be due to several reasons, such as a clogged transmission filter, low transmission fluid levels, or a faulty transmission solenoid. It is recommended that you take your vehicle to a qualified mechanic for diagnosis and repair to ensure that the issue is addressed properly.

if you mean range sensor is in side the transmision atached to the valve body

Jesse A Shelby, my best guess is the
(transmission control module) you said check engine light is on that means codes are being stored , OBD needs to be scaned that's a start. (interesting name).

You go to a qualified transmission shop and let an experienced technician diagnose and repair the problem. (Unless you can read and understand all the codes from your TCM, and have the equipment to check fluid pressures at all the test ports)
Resetting the check engine light is obviously not correcting the problem - it comes back as soon as you get into stop and go traffic. Your transmission is going into limp mode, which is what it's supposed to do. Just enough to allow you to get it to a shop and get it repaired. Continuing to drive it this way may do further damage to the transmission. What may now be a fairly inexpensive fix (sensor, solenoid, etc), may become a very expensive fix.

OK... brains are expensive. It sounds like your PT STARTS OK, but keeps your TRANSMISSION locked.

Many transmissions have a 'lock' that is coupled to the car BRAKES. So the transmission may not allow SHIFTING if the BRAKE SWITCH is not sensed as 'brakes applied'.

APPLIED BRAKES = OK TO START/SHIFT. So it's possible a defective switch is your problem?

How To Solve The PT Cruiser Transmission Problems

And there is this: "You Probably have a 604 41 TE auto trans (this is a four speed automatic trans)and if this is the case. Then you need to have the input and the output turbine sensor's replaced,(aka speed sensor) same thing different name. These sensors are cheap and have a high failure rate due to high temps the trans produces."

Check light on , have codes checked . Transmission not shifting into a gear , could be a shift solenoid . Take your vehicle to a qualified repair shop , before it get's ruined .
