Automatic transmissions are very sensitive to the engine running perfectly. When did you last perform a service? Is the idle speed high? Is the crankcase breather tube broken at its joint with the T piece underneath the engine acoustic cover?

Hello, how to insert photos? I checked the crankcase breather tube and i think it's already affected: there is some mastic on the T.

Well done. That's best renewed then (LLH 102660). You don't want a vacuum leak there!

Hello, I’m going to replace the part. I would go to an automatic transmission specialist for my problem. For the moment we are confined to France.
The gear changes are not very harsh but I feel them especially during the kick down and when I brake.

Renew the defective crankcase breather tube then go on another test drive. As I said, if the engine isn't running smoothly it can affect the operation of the automatic gearbox.

Unhappy

Good evening, gentlemen.

I had a problem with my gearbox today.
I was on the highway at 130 kmh.I accelerated hard to pass a car , the engine speed rose gradually and then remained stuck at 7000, then went down to 6000 and again at 7000 for several seconds. The top gear did not commit. The car was grazing a lot. The phenomenon happened with every speed.

I went home because I had no fuel. I went to refuel and I tested again on the highway but the phenomenon did not recur( I still have my gearbox problem that I explained at the beginning of this post).

What do you think?

just been reading this post. you say that the gearbox has harsh changes bumping when selecting gear and then whilst driving shifting gears . i dont know if i am correct in saying that the cambelts were changed before this started ? the reason i mention this is because i had a similar problem after i changed my cambelts. in my case it was just a plug in the engine bay which i had connected wrongly. when the belts are changed the inlet manifold ( upper black plastic one together with the throttle body ) has to be removed and the plugs disconnected underneath. there are 2 plugs that are exactly the same . one is for traction control that might be used or not depending if you have traction control.even if not you will probably have the plug in there. the other plug is the t.p.s sensor plug. ( throttle position sensor ) they are exactly the same and can be mistaken for each other. they will both fit in the plug holder on the throttle body and it is an easy mistake. you will find this plug if you search at the side of the throttle body follow the loom cable down and you will find the other disconnected laying underneath. it took me 2 days to realise what i had done before i found out. try this and see if it works if not then just plug the other one back in. try it . xsport. ....

Hello, today the same phenomenon occurred on the highway. Yet I still have 11 litres left in the fuel tank.
The vehicle stalled and I stopped on the side.
What do you think? fuel pump? Unable to restart.
I put back 15 liters of fuel and it restarted.

Do you mean the high revs mentioned in your last post?

It's unlikely to be the pump as they are very reliable but if the crankshaft sensor signal is lost due, for example, to damaged wiring, the pump will stop running.
