My Carina 5 is released

Hello. Good morning.
I have a toyoya Carina TD and for a while to this part. The fifth speed is raised. After half an hour of driving. It didn't happen before. Then I reduce speed third, and from there to fifth. And he usually takes another time until he stopped stepping on the accelerator, which returns to Sali.

Can someone advise me?

Hello, well for what I understand is likely that a motor support is damaged that makes the accelerator release the speed.
Another cause would be that your gearbox has inappropriate oil and that was probative the wear and tear of chisters or proven you discarded in the cectoring axis of change (this is sometimes resolved by giving more pressure to the spring of the 5th speed) greetings.

Hi Sorto.
Thank you very much for your answers.
The truth that I thought the worst.
I tell you too. That when you leave from standing, it works without problem for a time. Until the fifth speed spit again. And it only happens to me with this speed.

Thank you very much Sorto

I agree with Sorto, Czech supports or have a neutral test accelerates the car looking at the gear lever if it moves forward or back then it is support.
