Solutions for Jaguar Automatic Transmission Jerking

Jaguar is a luxury car brand so when you are driving one, you expect a smooth ride. But when the gears of your automatic transmission car start to jerk during a shift, it becomes a problem. This jerking sensation is usually a result of problems within the transmission; however, it is not something to worry about because it is not an irreversible issue. There are solutions that you can do to diagnose and rectify the situation. Below is a complete guide that will enable you to diagnose and repair automatic transmission jerking in Jaguar.

Fixing the Jerk Experienced by Jaguar’s Automatic Transmission

• Check and Refill Transmission Fluid: Begin with the transmission fluid check. Transmission fluid is used to lubricate, cool, and help in the smooth shifting of your car’s transmission. If the car starts to jerk when you shift gear, then you need to look at the fluid levels. Find the transmission dipstick, which is normally situated at the rear part of the engine compartment. If you have any doubt regarding the location, it is always recommended to check the manual of the vehicle to locate it. This should be done with the engine running; pull the dipstick out, wipe it with a clean cloth, and then insert it back before pulling it out again to read the fluid level. The fluid level should be at the position in between the ‘full’ and ‘add’ marks. If it is low, you should top it up.
• Change the Fluid: Check the state of the fluid; it should be colorless with a tinge of red color. If it looks black, greasy, or has a burnt smell, then it could be responsible for the jerking problem that your Jaguar is experiencing. If this occurs, you should quickly replace it. Start by flushing the old transmission fluid out of the system. Find the transmission fluid drain plug on the floor of your car, put a jar below it, and unscrew it. Some transmissions also have a filter that needs to be replaced during this process. Consult your automotive user’s manual to know how to get to this filter and how to replace it. Once the old fluid has been drained and the filter replaced, add new fluid to the transmission. It is important to use the type and amount recommended by your Jaguar manual.
• Reset Transmission Control Module: There are times when the jerking problem may be caused by the TCM. This module regulates the flow of power, and at times, may develop some problems resulting in jerking. To reset the TCM, you have to first remove the negative terminal of your car battery and wait for about 15 minutes. Reconnect the battery afterward. This simple reset can clear minor issues and might solve jerking issues for you.
• Check Error Codes: The next crucial step is to look for error codes. Modern automobiles, such as Jaguars, that have automatic transmissions, contain built-in diagnostic capabilities that allow for the storage of error messages associated with transmission issues. You can see these codes with an OBD-II scanner. Buy a scanner or go to an auto parts shop that provides free scanning for the check. Connect the scanner to the OBD-II port, which is usually found under the dashboard, and scan for any codes that may have been stored. Search for the meaning of these codes in the manual of your car or on the internet. If there are codes that suggest that there is a transmission problem, then it will require the expertise of a mechanic.
• Replace Worn Components: If the jerking problem is not caused by transmission fluid and TCM failure, it might be time to inspect the transmission’s internal components. Jaguar transmissions have so many components that can get worn or damaged over time and you cannot repair these components with a DIY approach.

It is recommended to go to a reputable mechanic who deals with Jaguars, can quickly identify the issue, and suggest how to solve it.
