This transmission shudder is a strange one, I have a 2012 sport auto, and have had some problems with a rattling / grinding noise from the transmission when it changed from 3rd to 4th, this was diagnosed by my dealer as a fault with the transmission and they fitted a new clutch assembly, and the problem has gone, and the transmission is smooth, and has no shudder , or hesitation, or noise.
The thing is at no time did mine have a shuddering or hesitation issue, only the now gone noise, but a mate of mine who has a 2013 Trend, has the hesitation problem, he had a drive of mine recently and said the difference in mine and his was chalk and cheese, so what is it that only some cars have this problem, you would think that if it was an inherent problem with the transmissions all Focus cars would have it, but no.
