Automatic transmission will not work

you have a bad speed senser

Check engine light is on because you need to have your vehicle serviced. Take it in, don't wait too long or you'll have bigger problems. It could be a very minor problem but the longer you wait, the more could go wrong

Check the oil level in the transmission to check for oil leaks . Run fault codes and look for a fault in the TCM unit or wires not connected properly. Have a pressure test done to check for internal problems.

Go to any auto parts store auto zone O'Rielys Auto parts whatever tell them the kind of car and the type of engion wheather automatic or standard trans they will tell you the right kind of transmission fluid to use

HEADLIGHTS COULD BE BAD CONNECTION OR LOOSE WIRE. WIRE CONNECTION OR BAD DRL RELAY.CHECK TRANSMISSION FLUID LEVEL.IF FLUID AND FILTER HAS BEEN CHANGED CHECK THE MANUAL SHIFT LINKAGE ADJUSTMENT.IF ALL IS GOOD YOU HAVE PUMP PROBLEMS OR FORWARD CLUTCH PROBLEMS.SCAN TRUCK FIRST BEFORE SPENDING A LOT OF MONEY

it sound like you have a vacum leak or your shifter cable may need adjusted

The vehicle speed sensor and speedometer are one in the same on this model I believe. If one goes out it takes the other with it if its all electronic and not cable driven.

First check the transmission fluid with the engine at an idle (for automatic transmissions) and take note that there is a cold and hot level on the dipstick. Hope this helps. Good luck

try the vehicles vss (speed sensor) it will definitly cause the speedo to stop working and the hard shifts. When your vss goes out it automatically goes into LIMPIN mode to protect the transmission from from damage. the vss is located next to the oil filter and looks similar to small distributor.Its about 130-150$ but it should solve the problem. I have been doin transmissions for about 8 years i hopes this helps you.
