hi guys i have a 58 buick century which i bought in idaho last year and imported to the uk it was a good buy and i'm happy with it but i have a problem with the dynoflow trans i have no drive from cold i have to let it warm up for about 5 mins then its ok so i'm looking for a spare trans to rebuild i dont want to take it off the road i just want to change the trans one for one so what i need to know what year trans will fit or is it only a 58 that will do any info will be a great help as there not many 58s in the uk and the cost of shipping a trans from the us is out of this world. regards rusty GOD BLESS AMERICA
