Many Thanks for that an intersting thread I did not realise so many were affected. Do you think at 73000 I should change it anyway. Last Year I had a Grand Cherokee an 03 and what a load of rubbish that was, every time I drove it and it warmed up, if I stopped and turned the engine off,when I re-started it, it would not change up, seemed to keep going into limpin mode.
I don't have the service book and can't seem to find any info on servicing schedules also what oils pas fluid, etc to use.
