Well fellas it seems I have a bit of a dillema on my hands.I can't decide which torque converter to get. This is gonna be used on my 2006 K1500 crew cab 6.0 with a radix. I plan on running a FLT level 5 4L70E behind this as well. After I get the trans in I am gonna pulley down some and get a street and dyno tune from Nelson Performance in San Antonio. I do tow from time to time with this truck. Anywhere from 2-4k and 5-8k on rare occasion. So it needs a converter than can still handle the stress of towing and not be too loose and have problems towing. I am also gonna get a big tranny cooler to keep the temps down. The truck currently has 265/70/17 bfg all terrains and 4.10 gears. I have been doing alot of research on the subject reading up on old threads on here.
So far its between the Vigilanti 10.5" lock-up Multi- Disc 3 plate 2400-6000 RPM's http://www.converter.com/vigilante.htm If i was to get this converter it would more than likey be a 2400 or 2600 stall. I e-mailed Precision Industries earlier and asked them what they thought, waiting on a reply from them.
Also, I emailed yank and told them what I have planned for the truck and that I do tow. They recomended the Yank SC3000 for me. A few people are running the Yank SC2800, would that be ok for towing? Does yank make a SC2600 or SC2400? I just think a 3000 stall would be a little high to use with a roots type blower. Here is the link to the yank converters: http://www.converter.cc/converters/truck/truck_main.htm
From reading up on old threads on different sites, it seems the SC yank series converters are a little looser than the Vigilanti ones. It also seems you want a bigger converter if your gonna tow so a 9.5" would be outta the question. There are also a few people that say to stick with the stock converter. Would this be a wise idea, or would I just end up blowing up my new trans? Thanks for all the input/help guys.![]()
