NO I think your forward band broke can you manually shift it to low & car moves If so you need trans overhaul. Don't have that mechanic fix your car he is full of it if converter failed or (SENSOR!!) you would also have no reverse

What would stop a transmission from shifting ?


On a newer car this is a mode the transmission goes into when there is a bad problem with the transmission. It will usually go into 2nd gear where you can drive it safely to get it checked out but will not shift into any other forward gears.

May be a bad Torque Converter Clutch solenoid, or bad torque converter itself.

Now i dont know a lot about automatics especially modern ones with all this fancy electronics thats used nowdays but i think its a fault with the temperature sensor for the gearbox.But where its located and what it looks like i have no idea it could even be mounted inside the gearbox .Sorry not a very good answer from a mechanic but?? very few of our europeon cars come with auto transmission .Evan when i do know whats wrong i cannot buy the parts for the gearbox as only re-con boxes supplied by the dealer so best advice is to try a specialist in auto box repairs only .PS some of my best students when i used to teach mechanics many moons ago were the girls so no excuses like iam only a girl please

It wont go into gear


sounds like you have a bad torque converter

My 92 Ford Taurus has had shifting probs for about 5yrs, but recently it wouldn't catch any gear to move forward, and severely "bucked" in reverse. Mechanic says it might be speed sensor,...


Some speed sensors will help the transmission know when to switch gears, but with some of the things you describe, sounds like after driving it that long, damage to the transmission has occured. Also, it could be a bad torque converter. There is also something called the transmission torque converter clutch solenoid, causes the car to buck and cut off. Hope this helps, any questions just contact me.

Sounds like you need a new transmission. It can only be one of two things: Transmission is old and needs replaced or the torque converter is bad. But if your going to replace the torque converter you might as well make sure you have a good transmission because you have to drop the transmission to get to the torque converter. No point in droping the transmission and replacing the torque converter to find out you need to drop it again because the transmission is bad. You should be able to drop the transmission is a few hours. You only have 3 bolts on the fly wheel and one bolt for the transmission mount and about 6 bolts connected to the engine. Then you have your fluid lines speedometer cable and drive shaft. And your dip stick.

Hyundai Santa Fe 2005 won't shift into first gear


Most likely the o-ring seal between the torque converter and the transmission is going bad. Get that transmission rebuilt pronto before serious damage is done! But first, have a mechanic drop the transmission pan and look for signs of a very thin silvery film coating the inside of the pan. If found, then the transmission definitely will have to be rebuilt, and the torque converter will also have to be replaced since embedded metallic particles in the old torque converter will eventually come loose, due to wear of the clutch plates within the torque converter, and eat up the rebuilt transmission. Now, here is the deal once the transmission has been rebuilt:

Change the transmission fluid and filter once a year -- no matter what! If you do this, then you should never have any more problems with the transmission.

E4OD Trans stays in OD no matter where the shifter position is.


Transmission Description The E4OD transmission is a fully automatic, electronically controlled, four-speed unit with a torque converter clutch. The main operating components of the E4OD transmission include a torque converter clutch, six multiple-disc friction clutches, one band, one sprag one-way clutch and two roller one-way clutches that provide for the desired function of three planetary gear sets. Transmission gear selection in the (D) range and converter clutch operation is controlled by the powertrain control module (PCM) (12A650). Operating conditions are relayed to powertrain control module by various sensors throughout the vehicle. The powertrain control module compares these conditions with electronically stored parameters and logically determines how the transmission should operate. A torque converter (7902) couples the engine to the transmission gearset via the input shaft (7017) and the torque converter impeller hub. The impeller hub provides engine rpm to the positive displacement pump. The flow from the pump is proportional to engine rpm, and excess pump capacity is exhausted back to the pump inlet. The input shaft transfers power into the transmission gearset. The power input is controlled by the application of the torque converter clutch, which is scheduled through the powertrain control module. The application of the piston plate effectively replaces the hydraulic coupling between the converter cover and the turbine with a mechanical coupling between the converter cover and the turbine hub. This mechanical coupling helps improve fuel economy and wide-open throttle performance by eliminating converter slip. Transmission shift selection and torque converter clutch operation are controlled by the PCM. They are calibrated to provide the optimal transmission state. This state is commanded to the transmission solenoid body. In the (D) range, automatic operation of all four gears is possible. The transmission control switch, located on the vehicle's shift lever disables overdrive operation and enables automatic operation through the first three gears. Whenever the ignition switch is turned on, the vehicle will automatically provide overdrive operation regardless of the switch position the last time the vehicle was running. Manual gear selection is available in the 1 and 2 range. Second gear is commanded when the gearshift selector lever is in the 2 range and when downshifted into the 1 range at speeds above approximately 56 km/h (35 mph) (for diesel 48 km/h [30 mph]). First gear is commanded in the 1 range at start-ups and when downshifted into 1 range below approximately 56 km/h (35 mph) (for diesel 48 km/h [30 mph]). Any reference to intermediate brake drum or direct clutch cylinder are one and the same.

I think this is your problem:

Programmable Speedometer/Odometer Module (PSOM): Description: The programmable speedometer/odometer module receives input from the rear brake anti-lock sensor, which is mounted on the rear axle differential housing. The PSOM processes this input signal information and relays it to the powertrain control module and the speed control module. This signal tells the powertrain control module the vehicle speed in miles per hour (mph). Used as an input in determining shift scheduling and electronic pressure control. Symptoms: Harsh engagements, firm shift feel, abnormal shift schedule, unexpected downshifts may occur at closed throttle, abnormal torque converter clutch operation or engages only at wide-open throttle (WOT). May flash transmission control indicator lamp. Diagnostic Trouble Codes: 452, P0500, P1500, P1501, P0503

No forward or reverse? You have tried 2 and 4 wheel and 4 low? If yes to all, the transmission pump is bad or the torque converter is bad. Check line pressure.
