Check that the air filter is clean and the oxy censers are working , if the censers are defective the computer can't control the air fuel mixture,
I would think the mechanic had checked for codes or history of codes. If the cause is a defective converter there is not a lot you can do except replace. You cannot repair a catylitic converter.

Hi Guys!
I work in a transmission and torque converter remanufacturing plant and have seen this many times! I hate to tell you that your transmission is shot! There is metal in the fluid and some of it got caught in a solenoid not letting fluid through to shift the gears. You will need a rebuild! About $2500 dollars. Of course if you in Pittsburgh, Pa. area I could do it for about half that. Any questions e-mail me at [email protected]
Check the fuses under the dash on the drivers side, next to the steering column. There should be a fuse puller on the fuse box door. Also a chart of which fuses at what so you can go to the proper fuse. Good luck, Please let me know if this is the solution to your problem.

HI, this could possibly just be a simple as a set of bad steer tires. make sure the front tires are balanced and you front end has been properly aligned recently.
Now, if the tires are new or, they have been rotated and balanced properly recently, i would then move on to the alignment process. if you front steering Assembly has been aligned properly and, you still have this shaking at 50 mph, this will confirm a more serious issue concerning the power steering gear. i would then check the tie rod ends for ware in this case.
next, check the idler arms as well. make sure the intermediate shaft is tight and, the entire rack or, circulating ball Assembly is tight and, not loose.

You can check fluid level by removing the rubber plug in the cover. Fluid is full when on level ground, it is just at the edge of the hole (or very close) if you are already getting noises out of there, you can remove the cover and inspect gears for wear or breakage. If you find a large amount of metal debris in the lube it tells you something bad is going on back there. Although rebuildable, it's not a home job...requires exact settings in order to operate properly. You can find good units far cheaper than even a gearset costs in any scrapyard. to match ratio, count the teeth on the ring gear and the pinion gear. the replacement MUST have the exact same number. Before swapping diffs, check all back there to make sure noise is not from somewhere else.

trade it in on the scrappage scheme against a new one .or take it to an authorised garage for emmisions ,cant just point a finger at a certain component and say change that .Sorry but without the right equipment i would only be making educated guesses .What condition is the air filter in ---did you clean it before you went for the test
