Tranny problems?

[GOZAR]

Recently with my evolution turned on the extreme setting at higher rpms and at redline my transmission will shift like its got a "shift kit" in it. Some times it will slip and sometimes it will want to shift and wont then shift and put u back in your seat. The 4r100 is a pretty well built tranny from the factory but im wonder if after time can it handly shifting this rough. Who is running a built tranny? Suggestions? I do alot of towing and like to do alot of racing. My tranny is getting a little sloppy with age (130K) and im thinking about beefing it up. A buddy of mine quoted me $1250 for a rebuild,good converter,shift kit, better pump, and good beefy internals. Just wondering to see what everyone else has done. I am a mechanic and im pretty knowledgable but im am just starting to get into diesels. Thanks

i think the quote that ur buddy gave u isent a bad deal for a conveter shift kit and better pump if that includes r&r of the tranny i dont think that u couldetn beat that deal just let him do that if not i would go with an ats or bd transmission but they retail for like 3500-to up to like 4300$$
