Automatic that won't go into gear.

Check the shift linkage cable and make sure its in place at the transmission.

Hi there,

Most modern automatic cars require the driver to depress the brake pedal first, to allow releasing the gear out of Park.

Some automatic transmissions also provide an 'overide' switch near the gear lever, to allow manual release of the gear lever.

If neither of the above resolve this, then you will need to check the operation of your brake switch, mounted on the brake pedal.

change fluid start there

Have a trans shop road test & come up with something

either your fourth gear control solenoid is bad or trans is going out. ck fluid level and look , smell if burnt trans is bad . have scanned to ck fourth gear solenoid.

bad shifting piston in ******

If the RPM's Flare, youv'e gone too long without
recognizing a trans that slips

It will have to come out & be rebuilt,most likely.

Could either be your shifting linkage needs to be adjusted or your transmission solenoids need to be replaced

Assuming the pickup is an automatic, check the transmission fluid. The #1 cause for transmission slippage is lack of Automatic Transmission Fluid.

If the pickup is a standard shift, the pin that connects the shift to the transmission has likely broken. You would still be able to shift from the inside but the gears won't engage. A bad clutch is also a possibility but you would have noticed a burning smell prior to the clutch giving out.

You probably won't find one. In an automatic transmission you cannot just simply remove gears or change the selector fork (especially because there isn't one). Everything needs to be there or it won't work at all.
