Sequential transmission is not working right

This car has the option to change gears from the steering wheel .Car stall when starting to drive if I don't give enought gas , also car grind when changing gears more noticeable in 3rd gear. Thank you so much for your help.

    I have a 2002 toyota mr2 spyder, and everytime I start the car, I have to wait for the transmission gear indicator (exclamation point inside of a gear-like indicator) to illuminate. The transmission then can engage the gears and operate. It also stops and stalls frequently, thus leaving me stranded in traffic for a good minute. I diagnosed the car recently and pulled out a DTC code "P1781" stating the problem is within the transmission control module (TCM) . I then purchased a newly updated TCM with the part number 89535-0W041 as recommended by AllData from the dealership.I did the re-learning process, but it still won't engage the gears. What should I do now?? Please, anyone with this problem or any relation this problem, please respond asap.

My son just brought our MR2 with the same 3rd gear crunchy problem to the transmission shop. They said it is a faulty speed sensor which is engaging the clutch at the wrong time. A $200 fix!

My nissan murano SL 2005 goes in gear but it won't move either in D or R position. Kindly assist

You don't need to worry about the steering wheel with this as they are not connected to each other in any way.
Are you getting any changes at all? OK, with the engine running, does the car feel the same when you select D or R? Do you feel the car change slightly as the gear engages and the sound of the engine slow slightly as the engine connects to the transmission?
Or does the car feel the same and the engine sound doesn't change. Is it only the Shifter stick moving and the indicator light changing?

My nm model pajero exceed will go into 4 wheel drive,but will not disengage.any ideas

Hi Jim,
this is rather common. The front axle diff will have a hard time disengaging if the gears are under load. You need a load change (get of the acc pedal, move steering a bit left right, briefly go to neutral on the auto transmission, then back to drive). This will help to get the front diff loose again. Sometimes it really takes some time to disengage! Mostly the problem is gone when you stop the car, switch off engine, release brake, then start again and drive - and voila- back to 2WD. On hard surfaces the transmission can go into a wind-up state (because of different wheel speed when cornering), esp the center diff (4WD and center diff locked) then is under such load that the car virtually stops driving or you can hear crackling noises and tyre slip on tarmac!

I want to change my steering wheel from the left side to rigth of car to drive from the rigth

If they made a right hand drive model you would need to get the front clip, steering, harnesses, dash and interior for it. Then have a body shop remove the front of your van and install the front from the right hand drive. Literally everything from the steering wheel forward would have to be removed in order to make it work. You would be looking a tens of thousands of dollars to make this happen.

98 freelander stalling fault

Explore the problem to see if its the power steering, or physical steering or engine:
Does it stall when its in neutral and you go to full lock?
If so its the power steering, or the engine isnt ticking over fast enough to generate the extra pump pressure needed when on full lock. Check pump belts are good and tension is correct. Then buy a used idle valve and swap it out.
Also do basic checks to see if wheels are catching on some part of car. Jack it up so front wheels are off ground, on full lock in neutral do the wheels turn freely, or catch on something? Slowly lower the vehicle down and check same as you do it. When its down put it in gear and see if it stalls.

2001 outback automatic stall.

When you changed the ****** fluid was it brown? If so I regret to inform you, you may need a new transmission. The brown color is due to the clutches in the trans, wearing down over time. Does it shift hard when you drive it? If it does that is another sign the trans has gone out the window.

Greetings, My car started showing some issues yesterday, it gives me a sign, 4low! don't know what means and it has started performing complitly different and slow, is not changing gears too!...

On any suv with 2 and 4 wheel drive options 4 low generally means that the transmission is in 4 wheel drive low gearing option so that the most possible torque is transferred to the wheels by way of what would be called a granny gear. What you will need to do is check your 4 wheel drive settings to see if the transmission has been put into this option which is either on a separate shift lever or a push button either on the shift handle or on the dash. Your owners manual should also direct you to where the selector is at.

I think I have a timing issue. My car takes a second to start up and the car jolts when it changes gears. Also, my steering wheel shakes left and right when I'm driving at low speed

Ok,

same car with the AC problem. Timing is not going to make this all happen.

  • If its jaulting as an automatic, through the gears, then probably check and change the fluid and the filter in the transmission. Usual jolting is from lack of fluid pressure, caused by lack of or blocked filter.

  • Start up could be anything from a weak battery to lack of fuel/choke. Try a new fuel filter, air filter element, check your oil and change the spark plugs.

(Symptoms of bad ignition timing are misfire and run on also extreme lack of power and rough idle. The car will also shudder and keep running a few seconds after the key is switched off.)

  • The steering shaking from left to right at low speed could be a few things. Is it only happening at low speed? Sometimes its hard to tell at high speed as it is happening so fast the frequency is almost unable to be felt. However when you brake it should be pretty strong if its a mechanical fault, ie disc warped or bent wheel.

1999 Regal GS -stalls, starting trouble, won't shift now

the batt is suspect...take it to autozone, or other place, they'll check it out free......the shifting out of park is a seperate issue, the pawl for the steering/shifter is not working properly....did you notice if the steering wheel would turn when the shifter is stuck?....probably not....when this happens try to turn the wheel back and forth-not hard but not gently- a little graphite dust sprayed in there would help.......hope this helps you out

Transmission doesn't stay in one gear

possible faults - *check the shifting cable selector is aligned with the neutral starting switch * check engine mounts *make sure the fluid level is between the marks on the dipstick running hot * overdrive friction and drive plates have worn out * the torque converter or oil pump has a problem *do a torque converter stall test hope you used only mitsubishi automatic oil when changed *check the throttle position sensor * temp sensor for the auto the TCU has faults or needs to be replaced
