Overdrive shift 2006 pt cruiser, 5 speed. was driving and the stick shift became loose couldn't change gears at all remained in 3rd gear until I got it home. y

When did you last replace trans filter and fluid? Dirt may be causing shift valve to stick.

Gear shifts happen depending on how far the gas pedal is
pressed & the load on the vehicle

Transmission pressures change as you drive under different conditions,so the shifts happen at different speeds

There is no passing gear

If you have a 4 speed,you have 3 forward gears & an overdrive
forward gear, plus torque converter lock-up

You saying you have no 4th to 3rd downshift or whatever

Maybe the transaxle is failing mechanically inside-worn out

I had almost the same problem, I checked to the bushing on the shift cables and they were gone. I found the kit at orielly's auto for $8. its a manual cable bushing kit

man you are loosing you gear box fluid ( valvulien oil ) go to gas station fill the gearbox check it if its dripping

2007 pt crusier Hard shifting manual 5 speed transmission in warm weather

When the car is just cruising along at approx.50+ MPH push the O/D button. You should feel the gears change higher and if you have an RPM guage then it should drop as well to fewer RPMs. This would be normal driving conditions. O/D will not kick in until the last regular gear (3rd or 4th depending on model)  had been shifted into. O/D automatically kicks out when slowing down and the transmission shifts to a lower gear. Thus the O/D has no function at slower speeds/gears and does not need to be shifted ( on or off ) except in the very first example given here.

There isn't anything wrong with your car. This is perfectly normal. I have a 2000 ES300 as well as other people that I know and it operates in the same way. Overdrive doesn't mean the same thing for every car or transmission. In our case overdrive is simply a reference to the top gear which is 4th gear. When you switch overdrive off(which is depressing the button causing the O/D OFF dash light to illuminate,) the highest gear becomes 3rd because you turned 4th gear or overdrive off. The application scenario for this is usually mountainous terrain where a lot of uphill driving makes it more feasible not to up shift into 4th gear while ascending and descending. It will not switch back to overdrive or 4th gear until you re-engage it by turning the overdrive back on or repressing the button. Again, when the O/D OFF dash light is illuminated, overdrive which is 4th gear is off and the highest gear will then become 3rd. It will never shift into 4th gear while this light is illuminated or overdrive is off. When you press the button and the O/D OFF dash light is NOT illuminated overdrive is on and therefore it will shift into 4th gear as usual. This applies to all 97-2001 ES300's and probably any other car you drive tat exhibits this same type of change when overdrive is turned off.
