Tranny Question

[ramairmustang]

Sometimes when im driving slowly when my car shift into 4th between 30 and 35mph it sounds like im running over rumble strips just for a second or two untill it completes the shift. What do you think is causing this? Or am I just accelerating too slowly for it or somthing stupid like that.

sounds like a torque converter shudder.

+1 on that. On streets under 50 mph, keep the OD off. Next will be 3rd gear shudder and then just shudder in all gears. The TC locks into OD at 39 mph and running around under 50 mph, you really don't need OD. When you stomp the gas and the car can't burn the tires anymore, you'll know what shudder is all about.
