SOURCE: wont shift out of 2nd gear but used to if you

Check cable from throttle linkage to transmission that operates throttle valve on transmission. Not uncommon for the linkage at transmission to be pulled all the way when gas pedal pushed for quick acceleration, or passing, and stay stuck there. Engine off, wheels blocked for safety and/or park brake on, have someone depress gas pedal all the way to the floor slowly, while you watch linkage that cable is attached to on transmission. Then as they release pedal, it should move back in opposite direction. Spray it well, with WD-40 or similar lube and get it moving by hand if necessary to make sure it is fully returning. That may be all it is.

SOURCE: wont take acceleration

Have you had the fuel pressure checked under a load? If the pressure is ok then check for excessive back pressure in the exhaust system, though that is rare on newer cars with Monolithic (ceramic brick matrix) catalytic converters.

Transmission shifts down abruptly when accelerating.

It most likely is a transmission issue, a internal issue inside the transmission.

Trembling while shifting on '02 F150 King Ranch

First-NEVER add anything to an automatic trans.
Your vehicle should use Mercon V --PERIOD
Change it at least three times, to get the Lucas out.

Have the TPS Sensor checked out.
You most likely have a Tran Pack Solenoid going bad.
It is bolted to the valve body. You can do it yourself

95 ranger 2.3l spark knock problem

Is this a manual trans in this truck, if so, try shifting down a gear. But yes a timing belt could cause this, but usually they wont run very well if the timing belt is that bad worn.
