Change or repair?
I have been asking a lot of questions on this forum and got answers that had helped me with the T-bird, so thank you all for these answers. Some questions was not needed as they was allready asked and answered by some one else.
I have done some modifications over the year that I have had the car (11 years) and so far they are:
3.08 to 3.55 including a Ford Racing Diff, Half shafts made in tool steel, the complete rear axle frame welded and support bars, Vogtland lowering springs, Koni adjustable shock, support bar between shock towers in trunk, front brakes from Mustang which needed 17"rims, engine from Mustang GT-04, 255 fuel pump, 24-injectors, cold air intake, and as a result 223 rwhp. There are more modifications, which I for the moment do not remember. I do some each winter and drive on the summer.
Now to my question and that is about the Aut. I have the 4R70W and it now seems to have reach the time of its life where it should be rebuilt or changed. What is your opinion? As the Aut is from 94, I think that it is of the first models of that Aut-type. Is it wort rebuild or should I buy an other? There are the 4R75W. If I should buy, from which models should it be?
