Hi All

I have a 98 XJ, recently it has started to shift hard up through the gears on initial start up when cold. Once the vehicle heats up then the shifting becomes normal again. I have checked the transmission oil and it is at the correct level with engine running in park, the oil is the correct spec. as per the user manual, and the service on the tranny was done around 4000 miles back? I only use the vehicle once a week on weekends, so it stands most of the time, what other obvious faults could there be, possibly a pump of some sorts needs to be replaced or should I do an oil change and service again, possibly something is blocked?

Regards

Mike
