I have a built 4l60 e out of my 94 z28. It has about 500 miles on it. It has all the best of the best TCI parts. Red eagle clutches and bands, TCI survos and sunshell. The only thing stcok in this tranny is the input shaft. It shifted smooth when cruising but bangs the gear when you rip it. The motor blew up and i since i bought a 93 with a fully built 396 strker so i have no need for these parts as i am selling my car rolling. I had about 1800 on this and i would like to see 1300 plus shipping for the tranny. The guys that did the work no longer works fro the company he went out on his own. The shop that did it was BOW-TIE transmission in columbus ohio. The techs name was Mickey. He came highly recomended to me by some of my buddie sthat work at JEGS. Also there is a TCI 2600 stall converter with 500 miles on it that i will throw in for 200 more if you are interested.
