Hey there, I'm looking into getting any information about strengthening the 4T60E. This winter I plan to pull the tranny and rebuild it, but am not finding much info on parts. Are there any common failure parts? I'd rather pull the tranny, rebuild once, and then not have to worry about it ever again.
Plans so far include a 3k high stall convertor, a 3.33 diff. w/ appropriate sun gear to achieve a 3.73 overall FDR, and having a company (don't know which one yet) retrofit it to a limited-slip. I read a while back that Raybestos was going to have performance clutches available for the 4T60E this fall, but haven't heard anything since then. Have any of you heard anything? Thanks for the help!!
EDIT: I also heard that there was a guy on here that built 600+HP TH125s. Im sure a lot of the parts are the same, or could be applied to the 4T60E. Does anyone have any info on those trannies? Thanks.
