Sounds like the tranny. Check the Transmission Fluid level and the color of the fluid.
check transmission fluid then go to transmission mechanic. problem may be in computer and be a simple fix
There can be several things that will an automatic transmission not to work properly. The most common cause is a lack of transmission fluid. Broken shifting linkage can also cause the problem.
It depends on what the problem is. From your question it is obvious you need to have it looked at by a professional.
Is yours an autoshift, or a fully automatic transmission? With the autoshifts, the synchroniser has a bad tendency to go out because of improper clutch manipulation. This shouldn't be an issue with a fully automatic transmission, however, and if that's what yours is, the first two culprits would be faulty circuitry in the transmission computer, or poor coordination between the computer in the transmission and the engine computer (this was a recurring problem for Allision automatics coupled to Detroit Diesel motors). There should be a way of reading off fault codes from the transmission, but that's going to probably require you to go to a mechanic with the necessary computer software to do such.
Could be a transmission problem, assuming an automatic transmission.
I had the problem on a 1994 with V6, sounds similiar. I think the problem stems from the safety locking mechanism that requires the brake pedal be depressed prior to shifting.
Problem with the transmission. You need to have the transmission computer checked for codes to know a possible cause.
That indicates a problem with your automatic transmission.
The transmission may need a flush and filter, or in my 92 accord I solved the problem merely by changing the transmissions computer.
The real problem is manually shifting from gear to gear with an automatic transmission. If you are referring to the automatic upshift, there may be a problem with the EGR system or vacuum system.
Most cars this is not a problem, the engines are identical.
There is a problem with the transmission, And the computer see's it and put the transmission into the FAIL SAFE MODE to stop it from blowing apart.You need to quit driving it and get it to a transmission shop ASAP.
It means that the trasnmission computer has a code in it. You need to read the codes in the trans computer to konw possibole causes.
Take it to a dealer or fully equipped service shop that can access the trouble codes stored in the vehicle's on-baord computer and they may be able to tell you exactly what the problem is.
The transmission fluid filter could be clogged. There could also be an electronic issue, run the test codes on the vehicle computer to see if a problem is shown.
A systematic plan for the automatic solution of a problem by a computer.
In an automatic transmission, there are many bands and fluid valves causing the vehicle to go into the proper gear. Testing the vehicle computer codes may show a problem but most likely a transmission mechanic will have to diagnose the problem.
My 1997 Dodge Avenger automatic transmission stays in 2nd gear a the time. What seams to be the problem?
Manual transmission: Clutch Automatic transmission: possibly low transmission fluid
The transmissions aren't made by Freightliner, and this answer applies to all commercial truck manufacturers. A fully automatic transmission is clutch free. An autoshift basically adds a synchroniser gear and computer operated shift mechanism to a manual transmission, and still uses a clutch. With an autoshift, poor clutch manipulation often causes the synchroniser gear to go out, making the transmission unable to shift. On a fully automatic transmission, that problem does not exist.
Does it really matter if it is a fuse or relay the key word here is "Transmission failure light" take it in and have it checked out the computer they hook it to will tell them what the problem is. Hope This Helps.
There is a problem with the valve body in the automatic transmission. It may stay like that, or it may get worse - no accurate prediction can be done without pulling the transmission apart to see what the cause is.
The transmission computer has detected a problem and set a code. It also has enter failsafe mode and locked itself in 4th gear. Have the system checked for codes. That will tell you or the mechanic what the computer thinks is wrong.
the computer and the ignition module give power to the injectors.
