Hello, I recently purchased a used 3550. I got a good deal on it, so I figured there might be a few things wrong with it. Only thing that I have found so far (it hasn't been installed yet) Is that the input shaft seems to be out of spec's. I don't have a Dial mic to check be specific but my guess would be that it's probably 10 thousandth's out on end play. I can also grab the shaft and wiggle it around maybe a 32ond of an inch. Also, when I turn the input shaft by hand the bearing (i believe it's the input shaft bearings) are noticable sound wise. If anyone has any experience with the 3550's or manual's please let me know what you think. Thanks for looking.
