Hi,

My 1998 Mustang has a vibration that occurs for two or three seconds when shifting under light acceleration at speeds of around 35-45 mph. It almost feels like the car is travelling over washboards.

Any thoughts on what is causing it?

Thanks.

Status: offline None. I found a service bulletin for mid-90s Mustangs (among other Fords) that described the symptoms perfectly, and it said degradation of the transmission fluid could cause it. I was just wondering if this is a known issue.

Status: offline I guess it could be. Every auto mustang I have had got a trans swap quickly. I never was a big fan of the AOD. Not when I have a C4 laying around anyways.
