I was just thinking myself that I ought to have a look Dean and this is what I found!! As luck would have it the governor had been earlier switched with that on other auto, which I remember did eat a seal and a section disappeared and clearly ended up inside. I have checked all the valves and passages. Another less on learnt I suppose, although perhaps the garage also should have cleaned the governor? With regards, Matthew T.

Here is a photo from before when the governor seal was eaten due to being badly fitted! Regards, Matthew T.

Interesting, i guess that if the seal gets forced into the oil gallery it has nowhere to go but get pushed into the valve, i would have thought it would be forced through and exhausted into the diff casing but obviously not.

Fingers crossed it will all be working well when it goes back together.

Stripping auto boxes is not my forte at all, so I'm following this with considerable admiration, Matt - not least of your persistence!
Hope a good result follows shortly. :P

unfortunately, this would have been at least part of the issue last time the engine and box had to come out, with a bit of luck this will be a nice easy fix though and normal service will be resumed shortly, good luck Matthew.

I couldn't see any difference in your two videos, but clearly see the valve is blocked by the ingested seal. I believe you will have fixed this now and gained a wealth of experience...MTXM Gearbox specialist opening soon.

It goes to show, don't leave anything to chance. Rush jobs always come back sooner, rather than later. Spend some extra time and check everything.

Many thanks for your kind remarks chaps and in response to Will you need full volume on your computer to hear the blasts of air and bubbling oil in the first video, which are conspicuosly lacking in the second video! The earlier incident with nipping and ingesting the governor seal was some time ago before I learnt the correct method of fitting and unluckily it came back to haunt me! I hope to report more encouraging news later today. With regards, Matthew T.

Hi Matthew.
I understood the damaged seal was a previous fitment. My comment was that when fitting or servicing items, to check everything thoroughly. What appears to be additional time spent is much less than time spent resolving a later issue.

My comment regarding the videos is that you appear to be blowing through the same oriface. Is that not so?

Good luck and I hope it's all fixed.

Thanks again Will and that is good advice I am sure. On the videos I was blowing through the same orifice but with different governors and I am sorry that was not clear. The news on the car is not great, since although the gears worked well initially and I had both first and fourth with quite smooth changes I then quite quickly lost all forward drive, so I seem to be back where I started about three years ago! There is still a strong reverse at least so the car can be moved. The best case scenario I guess is that I have a further governor issue (broken ring or seal) or a stuck valve in the chest, which are both highlighted as possible causes in the fault manual I checked. The worst case scenarios are burnt out clutches or a failure of the torque convertor, although I would welcome other reassuring more comments! With regards, Matthew T.
