Maybe the Throttle Position Sensor (TPS) if the computer thinks it is all the way to the floor then the gears would not shift until the engine RPM is real high. Also would not be able to determine the car is supposed to be idling. Do you have a check engine light? If you do this may come up on a scanner.

Check the trans fluid level first. To do this have the car running at operating temp check the level if low adjust to proper level and recheck. If thats not it I will help u trouble shoot it further. Sounds like a bad torque converter.

Hi Guys!
I work in a transmission and torque converter remanufacturing plant and have seen this many times! I hate to tell you that your transmission is shot! There is metal in the fluid and some of it got caught in a solenoid not letting fluid through to shift the gears. You will need a rebuild! About $2500 dollars. Of course if you in Pittsburgh, Pa. area I could do it for about half that. Any questions e-mail me at mach1cnc@msn.com

SOURCE: having problems with it shifting gears properly,

get a filter and fluid change in the transmission.
that 5 speed automatic is tricky.

do a code scan and see if there is a vacuum leak telling it to shift too late

Without getting into transmission diagnostics that would require special tools, you can check the transmission fluid level. You could also drain and replace the trans fluid to see if this solves the problem. Changing the fluid is considered regular maintence, and will not hurt a thing. The trans will benifit from fresh fluids in the long run also.

shifting is regulated by the valve body, governor and shift control module and solenoids...The bubbles bother me...Is it overfull ? If not, the filter or valve body may be loose and allowing air into the system and bleeding off pressure...however, this should make the unit slip.
Before it develops into something serious have a reputable shop check it out!!! (there are no "user friendly" items inside except the throttle cable, filter and checking valve body to make sure it's not loose (only saw that once on a recent rebuild though)

Shifting lever doesnt lock


Likely the shift detent mechanism is broken. It's inside the unit and can be reached by removing the trans pan. It should be just inside where the shift lever goes through the case.

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!
