Stuck in gear,with check engine light on,took battery of for 1hr,drove ok for 1mile.check engine light back on,stuck in gear.will not shift up or down.if you select low range the auto box will change normaly.

Code 100 and 101 are for problems with the Mass air flow meter.
Have you checked it ?
You can pin test the computer but you may need a shop manual to get the wiring diagrams.

this is limp mode most likely. is there a check engine light or abs light? if so, have code read. MOst likely its a speed sensor.

It sounds to me like you have a dead cell in your battery it can have 12 volts and not enough cranking amps, my shop has a tester that can tell you exactly what's wrong with it without removing it, however if you take the battery out and take it to autozone or advance they can test it for you.

could be something with the automatic combined the stift shift

probably the distributor. bad cam sensor. Rich Porter reman on ebay $200

This may sound crazy to you. Check the fuse that controls the speedometer, cruise control and interior dome light. My 93 f150 battery was going dead every night. One morning I noticed the dome light inside was still on. I couldn't get it to go off so I pulled the fuse that is under the dash on the driver side. Light went out and so did speedometer. When I drove it later that day it wouldn't shift from low until I let off the gas. Then it would shift around between gears for no apparent reason. It took me a day of two to put 2 and 2 together. When I put the fuse back in, the speedometer started working and it started shifting normally. I finally took the bulb out of the dome light and now all is well.On the 93 f150 the speedometer is electronically linked to the transmission shifting points. You may have other fuses that are linked to your transmission.

Alternator

you can get that switch at any major parts store or a dealer

If it is an automatic transmission it probably needs transmission fluid. If a standard shift check and adjust shift linkage.

When the trans. sticks itself in 2nd gear and stays there is because it's detecting a trans. problem and puts itself in "limp in" mode. When it happens again, to somewhere to have a scan done on the trans. so you can find out which sensor on the trans. is acting up.
