Will not shift out of 2nd gear

Tranny most likely shot. I believe yours is a T-5, I had the same issue years back but in 3rd gear. Usually the clutch going out is a gradual thing. So I would have a tranny shop look at it. Maybe find a cheap rebuilt tranny for ya.Look online or a trusted shop.

2006 Ford Explorer shifts hard between 2nd & 3rd gears, both up & down, but shifts normal between 1st & 2nd, and in & out of overdrive. All was normal then almost not working the next

It sounds as though your valve body may have a lot of particulates that have entered into it causing the valves to act sluggishly. Unfortunately, this is a condition that can only be taken care of by your mechanic and is not something that the average person can fix themselves.

Is it ok to start off in 2nd gear and manually shift up to 3rd and then overdrive?

You can put the shifter in 2, 3, or overdrive. It will still start in first and shift up to whatever gear you have selected. Try it, you wont damage anythingl

I have an 80 series landcruiser with A442F transmission, built 1993. It will not select 1st gear or overdrive. It takes off in 2nd and shifts to 3rd normally, 1st gear can be selected manually and changes...

It seems like your "2nd start" button is turned on. The 80 series LC has a button next to the shifter which allows it to start in 2nd gear. If the button is not engaged then there could be a problem with the circuit, but that is not common

When my 2001 GMC Yukon tries to shift into 3rd gear or overdrive - it is like it goes into nutral. It never shifts to 3rd. 1st and 2nd gears does just fine.

this sounds like the pressure valve is going bad on third gear. cheap fix try Lucus transmission additive to increase the pressure.
To do it right go to a good transmission shop an have it serviced and flushed.

1999 chevy lumina doesn't shift into overdrive, why?

If it won't go into overdrive a speed sensor within the transmission may not be sending the shift signal to the transmission. Check fluid levels to make sure that's not causing the problem. Also, check that the fluid is red color and clean.

Transmission probably needs to be serviced at a reputable shop if you want this problem fixed.

1999 Durango starts out in 2nd and shifts into drive fine regardless of what gear is selected. Even if 1st is selected, starts in 2nd. Reverse is fine. Will not shift into final or overdrive. Govenor...

I don't have the shifting schematics for THIS vehicle .
However, they are available in the vehicle's repair manual. If you obtain this manual look for what is common between 2nd gear, final drive and overdrive this is your problem.
Remember they source of the problem may require a rebuild of the transmission. You may want to save some time and just give it to a repair shop.
