        Hi. First of all, most cars do not go to 10,000 rpm. Six thousand is common. Are you asking something unusual is happening? It just could be the transmission shifting from one gear to another as the load demands are imposed on the engine. Please clarify the rpms as that might be relevant. oK? Good luck.
