I am in despair over my ("55) Speedster's auto. transmission after the transmission fluid started to boil about 170 miles into a complicated weekend excursion last Thursday. The car returned to London on an AA transporter and I continued the weekend on many trains.
History:
Mar.'99 - 72707 miles - Gearbox & Torque converter rebuild by specialists who do Jaguar boxes.
Oct.'03 - Engine rebuild.
Jan. '05 - 84216 miles - Major Auto. Trans, fluid leak. Gaskets replaced.
At some time since the the Rebuild, it started to make a grinding noise and a horrid, rough vibration through the car on changing from intermediate to direct gears, especially when accelerating but almost eliminated by letting up on the gas at just the right moment. This does not happen when everything is cold - only after running a few miles.
The fluid level was fine before my trip (checked according to Shop Manual) and was still only down a fraction when the smell and smoke made me stop - only it is now blackened. I stopped pretty promptly after the problem started, I am sure. It was a fine day and I'd travelled at 50 - 70 mph depending on speed limits with no "hard" driving at all. I was mostly able to avoid the nasty gear change by letting up on the gas peddle but there was one occasion after a hairpin bend on an uphill gradient where I didn't realise that it had changed down to intermediate and it made its nasty grating sound and feel on changing to direct. It was 5 - 10 miles later that I first noticed the hot smell.
What is going on, please? And what can I do about it? The garage that have looked after the car for 10 years say that apart from the black transmission fluid there doesn't seem to be anything wrong (!), but they will change and flush out the old fluid, get it all hot from driving and try to take it to the old chap at the gearbox specialists who remembers something of these old boxes at that stage.
Any advice would be greatly appreciated. I should like to keep the original gearbox (it also has the original engine) and I believe that being 6v. complicates a change to a more modern one in any case. Also I am exhausting my life savings in my retirement!
A very sad Peter in London.
