95 3.2 shudder at 35-45 mph

Hi, while driving at low speeds 35-45 mph the car shudders lightly as if there is a small loss of power. turning off the O/D seems to help, but it is getting worse. The car has 150K and has had the trans fluid changed 50K miles ago. Also, since I purchased it, the forst shift from 1 to 2 when cold has always felt like an old B&M shift kit in a turbo 350.

It sounds like I am Johnny come lately to the SHO trans problems. I plan to change the fluid and filter with your recommended Mobil 1 ATF any other ideas?

Does it do it when you're giving it a little gas? If it's only doing it with overdrive on, it could be old plugs and wires. If you're engine speed is real low (witch it would be doing 35-45 in overdrive with the TC locked up); and your ignition system isn't up to par, it could be your engine mis-firing.

Run your codes (good article on SHOTimes.com if you don't know how) and get back to us

Thanks, I ran the codes with the jumper for the check engine light. I am not a real genius on the code thing.
key off, 111-111-1------111-111
Engine running 1-11-111111-----1-1-111111
I guess I have a bad EGR, check tomorrow, and the engine probably was not hot enough.
I will pull some plugs tomorrow and check the resistance in the wires...
