Good Afternoon all. This is my first time posting on this site although I have been a patron of it for quite some time. My problem is I have 1998 Jaguar XJ8. Over the past months or so my transmission has shifted slightly hard between 1st and 3rd. The shift shock was barely noticeable, but I took it to a mechanic and got it checked out and they told me it was fine. And so I continued to drive it. I had read a post where a guy was having my same problem and his tranny later died, so I kept driving it cautiously and didn't notice it getting any worse. However yesterday i was parking and shifted into reverse and the car jumped and seemed to have stalled but as I gave it some gas it jumped and began to move. So I decided to just drive it home and park it but after that, whenever I came to a light or a stop and tried to accelerate, the car wouldn't move and then it would jump. And then the car went into transmission fault mode so it stays in 4th or 5th. I don't know what to do. I'm sure the tranny is bad, but i don't know whether to buy a new one, rebuild this one, or just scrap the car since I've had other problems with it in the past. Also since I'm a student, cost is important and if you could give me ballpark figures on cost that would also be appreciated. Thanks.
