Hard to put the car into 1st and 2nd,a tiny bit hard in 3rd, rest are fine.

ANSWER : The transmission internal gears have these special rings that synchronizes the gears using a special blocking ring that work together to help the gears line up and make them go together without grinding. If these special rings are worn out, then the gears will not align unless the gear you’re are coming from and going to are turning at the same speed and align up to change. Your transmission would need to be removed and the transmission disassembled to replace any worn out parts. One other problem you may be having is the transmission clutch not completely disengaging the connection between the engine and the transmission. This may be caused from the clutch hydraulic system or the clutch itself.

Have a certified mechanic inspect the clutch to see if it is fully releasing by measuring the amount of throw the clutch lever is moving to determine if it is working properly. If the clutch is releasing then the transmission is the problem.

ANSWER : The transaxle is not engaging internally to the axle shafts inside the transaxle or you have one or both axle shafts disengaged from the transaxle. The fact that the speedometer moves when gear is engaged and clutch is released shows the speed sensor in the transaxle is getting turned.

You will need to have the vehicle raised and the axles inspected for broke or stripped shafts. If the axles do not have anything visually wrong with them then hold one wheel and try to turn the other wheel while transaxle is in gear, with engine off, to see if the wheels are locked together. When you spin one wheel the other wheel should turn in the opposite direction. If it does not then the problem is in the transaxle differential gears and the transaxle would need to be removed and disassembled to find the broken internal components.

ANSWER : Hi there. What had happened is the wrong key set the security to the vehicle. This is to prevent the vehicle from starting with the wrong keys. Try removing the battery cables (+) and (-) for 13 minutes. During that time, put the original key in the ignition and turn it on. Activate everything in the car even though there is no power. Then remove the key and hook up the battery cables. The computer should have reset and reset the security. If the security is still being tripped, then I recommend seeking out a professional, such as one from Your Mechanic, to help you

ANSWER : There are reports that the replacement alternators will not communicate with the engine computer and will not charge correctly. I recommend using only the manufacturer approved replacement part. It can be new or remanufactured but approved for use in the vehicle. Some lower cost alternators on the aftermarket will have charging problems since they will not communicate with the ECM on the vehicle and will stop charging.

ANSWER : Hello. It sounds as though the synchronizers in the transmission, which are used to adjust transmission internal gear speed when upshifting or downshifting are possibly worn out or you are shifting a bit too fast. It is also possible that the clutch is not releasing fully when you press the clutch pedal. In some conditions, utilizing synthetic gear oil in the transmission can help the quality of gear shifting. If the clutch is not fully releasing an inspection of the clutch hydraulics is a good idea. I would recommend having an inspection of the hard shift completed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost for repairs.

ANSWER : The issue you are having is probably due to an intermittent fault in the starter motor itself or a deficiency in the starter electrical circuit, for example a large voltage drop due to a poor ground or a high resistance connection. These issues can be readily diagnosed and resolved on a mobile basis if you request a hard starting diagnostic. If you request that diagnostic, the responding certified mechanic will get this resolved for you promptly. Based on Toyota’s Factory Service Manual, the battery should not be disconnected if the vehicle engine is running. The battery acts as a large resistive voltage sink and consequently taking the battery out of the circuit, while the alternator is still running, can create a voltage spike on the car’s electrical system which is not good for voltage sensitive components such as the engine computer. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

ANSWER : With a car that cranks but won’t start, there are a few things that need to be checked. But before I explain them, there is a common thing that happens with Nissan’s. Every once in awhile they will flood the cylinders with fuel and wash the oil film off the cylinder walls and rings. This will reduce compression enough that the car will not start. Fortunately, there is an easy fix for this problem. It is what is known as clear flooding.

Hold the gas pedal all the way to the floor while cranking the motor. It won’t start immediately and when it does it will not run very well at first. Feather the throttle to keep it running until the motor clears out the excess fuel and the motor begins to run smoothly. If after cranking the motor with the gas pedal held to the floor for at least

ANSWER : This sounds like a faulty speed sensor problem. Most cars have two speed sensors (one monitors input shaft and one monitors output shaft) which tell the computer what the gear ratio is of the transmission while in use. If either of these are not working properly, they will cause the computer to shut the car off for safety reasons. I would suggest having an expert from YourMechanic come to your home to diagnose your stalling issuee and help you repair it.
