Message: [QUOTE="Chris, post: 654937, member: 400"] yes...there are. In my opinion its the daily driving the higher hp built 5rs that kills them rather than the drag racing. Weve tuned stock 5rs to hold 750hp for a while. and weve had 570-600 horse trucks eat built 5rs like candy no matter what we do with tuning. There is a variable about the 5r that noone has found. Maybe its something in the case, and maybe theres a big variance in the solenoids or solenoid packs. This issue weve ran across as a shop that installs what they sell, is its hard to recommend a built 5r when you know 3 or 4 out of 10 will eat up clutches every year. I have no doubt well make more progress with the 5r, but until we do we are working with Brian at BTS to streamline the 4r swap to be a more viable option. [/QUOTE]
