Message: [QUOTE="Denver, post: 873714, member: 608"] I had a 5r behind a 6.0 with this problem and kept having ford put transmissions in it. Truck was stock to. 2 transmissions had burnt clutches other 2 were fine and one just turned to soup and would start in 3rd from a stop. Years after selling it I was told the cause of the shift flair was because the way the trans uses gears. 1st gear is 1st gear. 2nd gear is really 1st gear with overdrive engaged. 3rd gear is 3rd gear. In order to go from 2nd to 3rd the trans needs to unlock out of 2nd and go into 3rd instantly. When it takes an extended period of time to unlock 2nd and engage 3rd thats were the flair comes from. If 2nd doesn't unlock before 3rd engages the trans locks up. [/QUOTE]
