Hello, some quick info about my XJ first:
98 XJ Sport
4.0L
Auto Transmission
Starting about a month ago, I have experienced an issue with what I suspect to be a faulty electrical component of my transmission.
The symptoms are as follows:
- While the car is in drive, when taking off from a stop, the car feels as though it is in neutral and will barely move forward.
- However, when the car is brought up to normal cruising speed (~30 mph), nothing feels out of the normal expect maybe a slight decrease in power.
- Sometimes the car is like this from the moment it starts up, sometimes this happens in the middle of drives.
I recently figured out that when this phenomenon occurs, the car will operate normally when manually shifted into the 1-2 gear and continuing to shift up manually (3 -> D). This is why I assume electrical issues.
The check engine codes that have been thrown are as follows:
P0700 (Transmission Control System)
P0758 (Shift Solenoid B Electrical)
P0715 (Input/Turbine Speed Sensor A Circuit)
In an attempt to fix these issues I have:
- filled transmission fluid and made sure it was clean
- cleaned 3 electrical plugs located near the transmission fluid dipstick
- cleaned the electrical grounds that are responsible for the TCM and PCM located on the left side of the engine block
Despite this, the codes continue to throw after 5-10 minutes of driving (However, recently the P0700 code seems to have gone away).
Looking for any help/solutions to these issues.
Thank you
