Normally repairing a transmission shifting hard problem can cost as high as thousands of dollars. And it, not something is neglected irrespective of the high repairs cost, else it could render your car totally useless.

Why does my transmission shift hard when I change fluid?

If you have not changed the fluid and replaced the filter already, do that while changing these parts. Otherwise, just keep the filter in a bag while changing the o-ring or spring and then re-install it. These are the most common reasons for the hard shifting problem.

What causes a transmission not to shift?

A lack of fluid or dirty fluid would cause the transmission not to shift properly. We recommend checking for transmission fluid loss, and using BlueDevil Transmission Sealer if the system is low. If the fluid looks dirty, you may want to have a transmission system flush performed and refill it with clean fluid.

What is a hard shifting transmission?

If your transmission is low on fluid, or if the fluid is old and discolored, it could be to blame for the hard shifting. Hard shifting can occur due to a lack of lubrication in the transmission. Transmission fluid should be reddish in color and largely transparent.

What causes shifting problems?

A worn clutch disc is the most likely cause of hard or difficult shifting. Check the clutch pedal free-play adjustment to insure the clutch is released completely. A manual transmission needs to spin down in order to shift smoothly. Excessive spin down time is more noticeable when shifting into reverse.

Why would a car shift hard?

Hard shifting may be caused by a slow sensor or one that is transmitting the wrong signals from the engine. A faulty speed sensor may be to blame for reporting that vehicle is running more slowly or more quickly than it actually is.
