Replying to: amadauss (Sep 15, 2009 8:10 pm) expectations versus reality in this case. All cars break. The only questions are what and when. If you purchased a new trans. and then it went out again in only 20,000mi. then that is a bad thing. Definately. The trans is one of the weak points of this particular model. Every car has something. In this car it's the trans. I wish I knew more about your driving style and the circumstances because even this trans lasts longer than 20,k mi. It does however have a weakness when parked on a slope. This trans developes problems when placed in park on a slope which will leave the weight of the car resting on the transmission. There are others with this problem and it can be cured by setting the parking brake before placing the trans in park. Not doing so is commonly known as hanging the car on it's transmission. We see this a lot in Oklahoma because of all the sloped driveways (it rains Hard here). If that is not your problem then I would look at the other things that can cause transmission problems which dont have anything to do with the actual transmission. I did a car recently for a customer who had constant transmission failure lights and default to limp mode. He had a bad transmission relay ($15.00) and then we found a defective speed sensor. After that he came back furious 2 months later that his transmission was defaulting to limp mode again. He could fix it by pulling over and switching the engine off and waiting for 30 seconds then switching the engine back on again. He would then have full performance for about 2 days then his trans light would come back on and the car would go back in to limp mode.(3rd gear only) We pulled codes from his ECU and found that the engine was missfiring. We had reminded him repeatedly that it was past due for his new spark plugs but he had always declined because of the costs of fixing his transmission. He was always good about keeping his car clean and we found out that he had been washing his engine as well. The spark plug boots were 9 years old and the last time he washed his car he apparrently filled 2 of his spark plug shafts with water. When the engine computer sensed the missfires it put the car into the default/limp home mode.(3rd gear only). We refused to fix the car unless he caught up on his spark plug and boot and coil maintenance. That cost him almost $1000.00 dollars but it was overdue by 21,000 miles. This car has been into my shop 4 times for transmission complaints. Once, when it was 8 years old for a new transmission. 3 times after that for just plain age and wear that were triggering transmission defaults. He has been in twice since then for oil changes with no more complaints. The ZF transmission starting in 2003 will not go into default no matter what the engine is doing. It also lasts about twice as long as the one you have. However, it is not rebuildable. When it wears out, you just replace it with a new one. The parking pall in the ZF is as strong as American cars and the Parking brake now sets automatically. That doesnt, however, help you. The weaknesses endemic to your model are yours and you can learn to understand and live with them or sue. I wish i could get my hands on your car so that I could see if you really have another transmission problem. If you do, and if its not your fault, then I can certainly understand your angst. It is just so unlikely that you could put in a new transmission and then have that one go out so soon due to a factory defect that I wish I could check it more thoroughly. Its possible, definately possible, but unlikely. Soberguy |

We're having a wonderful time with our 2003 STR - hardly any problems so far and lots of fun. Can anyone help me with the vintage of our car - the registration papers say 2003 but the sticker on the door says it was manufactured in 2002. So, are we driving a 2002 or 2003 Jaguar STR? When we order up parts (which I'm sure we will be doing sooner or later because this much fun must come at a price) which date would be the correct one to use? There seems to be a difference between the 2002 and the 2003 transmissions and this is what concerns me at the moment - what's ahead for my Cat - the 2002 problems or the 2003 problems?

Replying to: gr8cat (Sep 22, 2009 5:38 am) Canadian cars are the same as American. If you have the 4.2 engine then you have the 6 speed ZF transmision. This is a Very, Very, high performance car. Forget the vaseline, (you're just turning me on) and have a good tech maintain it for you. Amatuers can ruin an ownership experience. The most common problem with high output cars is fluid leaks. If you dont have a lift to allow you to see the undercarriage when you change the oil then you could miss things that you would like to know about before they become a problem. Just a suggestion, but that's a really high tech car. Working on it your self is like deciding to give birth at home. It might very well turn out OK, but, if it doesn't, well, the results could be heartbreaking. Wishing you the best, Soberguy.

Replying to: soberguyjaguar (Sep 22, 2009 7:01 pm) We're using Christo's JITS download for a manual and that seems to be working out just fine. This cat has a lot going for it but just a few bugs still to be ironed out - headlights are all out of whack, the bonnet flew up on me the other day at l00 km's per hour scaring me half to death and putting a few dents in the bonnet. Seems the safety catch took it upon itself to malfunction and the front brakes have suddenly developed a very nice shutter - perhaps a warped disc, who knows. One thing at a time. So far, these are the only "repairs" we'll be taking on ourselves. Replacing the headlight/ballast was a big eye-opener as to just how complicated this Cat is. Brits get the good stuff? I have to question that - remember a Brit designed this Cat - I just wonder where he got his engineering degree? He surely did not have "simplicity" in mind. Thanks. gr8cat

Replying to: gr8cat (Sep 23, 2009 6:14 am) New bonnets are expensive. Thanks for the tip about Christo's JITS and if you have the discs turned before the pads are ruined you might save a little. We have had terrible rains this month and are seeing a lot of warped discs. Soberguy. P.S. The design engineer got his degree from the University of low and sexy hoodlines.

Replying to: soberguyjaguar (Sep 23, 2009 7:00 am) Good advice on the discs - sooner the better. Do we really believe that brake discs warp in wet/rainy weather? I've had Ford Contour discs go wonky because of over-torqued wheels but I don't think we've had enough rain here in Ontario to warp the Cat's discs. We will have them checked out. ULSH sounds like the appropriate university. gr8cat
