This is a great question which we will discuss, but first let’s talk about the different ways an automatic transmission acts “funny.”
Slipping: When an automatic trans slips between gears — that is, to describe it as the engine revving up but the vehicle goes much slower than the engine seems to be racing, and then grabbing hold and back into gear, sometimes harshly.
Shuddering: This condition is when in gear while driving, it feels like you’re driving over rumble or alert strips at high speeds on a smooth highway. The whole vehicle shudders and shakes, as if having a convulsion.
