Check the level of the transmission fluid, low fluid can prevent the transmission from shifting.

1998 pontiac transport Van will not shift to 2nd gear but will drive on 1st gear 30mph...what can be problem


Could be a dirty oil filter in the transmission with out proper oil flow the pump has difficulty providing the right amount of pressure to allow the up shift. Check to fluid level if it's low add what your owners manual tell's you. Not always but sometimes a back washing the transmission can remove deposits left behind by clutch material's from the valve body intricate maze of travel. This can only be done by a transmission shop that offers this type of service. Most automatic Transmissions failures are caused by neglect long before high millage cause's trouble. A rebuilt transmission may be needed how ever that my over ride the value of the vehicle. I hope you can get your van back up & running as it should.

My 2001 vw jetta won't shift to second gear


run fault codes and look for a problem in the transmission. Check oil and coolant level as the light is a warning for both the engine and gear box and the failure to shift gears may be that the CPU has locked the vehicle in limp mode to restrict damage in the drive train units.

04 ram will not shift past 35 mph


it may not be a transmission problem. have you checked for fault codes to make sure it is not in limp mode? limp mode keeps vehicle from accelerating properly because the ECM has put the system at a limited setting to keep the engine running but not to its full potential.

My 98 mercury mystique is missing 3rd gear it goes 1st and 2nd fine but wont go over 30mph and no matter how high the rpm go it wont turn over into 3rd gear Help


The likely problem is the VSS or vehicle speed sensor. The transmission uses the speed from the speed sensor to determine the shift points. You should have the check engine light on it will probably show a code for the speed sensor. Hope this helps!

How do i check the transmission fluid level


Start the engine and let run until it reaches operating temp...next, run the transmission shift lever through all gears one by one and then return back to park. With engine running, pull out the transmission dipstick and wipe off. Reinsert the dipstick fully and pull out once more. Check the fluid level.

Automatic transmission


Transmission will never hold the engine back if it is going through the gears properly.If it gets into high gear, eventually the engine will reach "redline" if you stay into it long enough. ("redline" for any engine is the point at which it cannot run any faster without harming itself.) DO NOT confuse that with proper shift points which should happen just before you reach max torque which happens way before you reach "redline" at which point you are way past the torque peak of the engine, and making no usable torque or horsepower. An example of this is a race engine with a max rpm limit of 10,000rpm.("redline") Depending upon the torque curve (determined by compression, stroke and type of cam grind) you would likely be shifting gears at about 7500 to 8500RPM not at 10,000.
Therefore, your shift points are like climbing a ladder. you get just so high and though there are more steps, you will fall off if you go there. Each time you shift, you are putting the rpms back into the usable power band, till you reach the next step, then start over again. If your trans shifts early the engine will lug and labor. shifting too late and it will quickly reach "redline" and self destruct or go "flat". In a conversion, you need to make sure that the electronics that control shift points are working within the usable torque range.
OR install a manual valve body and shifter and control it like a stick shift car, using your brain as the computer and a tach to tell you where you are.
