Honda Jazz 2003 automatic gearbox transmission problem

[Bobby]

Hi guys. I bought for my girlfriend Honda Jazz for first car, but i think there is a problem with the automatic gearbox. During driving on D sometimes it's switch off and after few seconds coming back to normal. Also when is on D mode it's blinking. I went to Honda for diagnostic and i have been advised to change c/v/t speed sensors. I bought one sensor to see if it's work but there is still the same problem. I will be happy if there is someone who know what could be the problem.

Thanks

How many sensors did they have listed for it and can they be interchanged (if the same part number) so you can try the other sensors if faulty
