shifting prob

I seriously doubt it will effect the MPG. That is more an engine running condition relationship.

the engine runs fine though

Well, if the 'lockup' torque converter is not locking up, it will lower your mpg.

One way to check is to drive the car normally with the OD off. Feel the shifts, 1-2, 2-3, then watch the rpms, and see if they drop 2-300 at around 40mph.

You might even feel it. or hear the engine tone drop a tiny bit.

if you can't tell after trying it a few times, your's may not be locking up.

I wouldnt waste your time. I would go right away and have your tranny fluid flushed and changed.

You dont wanna screw up your transmission.
