Re: can't decide which converter?
Where do you go on the website? It's not under gm truck products is it? and it wont let me click on it in the homepage....Are the vig 3200's made specifically for our trucks?

Re: can't decide which converter?
sorry guys, been out all afternoon and haven't had the chance to check back in. tbyrne motorsports is having the vig. special. i didn't find it on the web site, i had to call in and ask. i also placed a call to precision industries, they didn't recomend any towing with the 3200. i'll be towing my buddies project grand prix, approx. 4500 lbs with trailer. looks like i'll be going with the yank, but still not completely sure.

Re: can't decide which converter?
I am sure you all have been asked this question a million times but....
What type of extra stress is this going to put on my 2003 5.3L auto tranny? Will it severely shorten its life? With a Yank 3000 or 3200 can I just cruise around or will the tranny kick in hard ALL THE TIME? Do you have to really "get on it" to get the converter to stall? If the tranny was always shifting/reving harrd I would think it would be pretty anoying.
Installing a Yank 3000 or 3200 would obviously void my tranny warranty but what about the rest of the truck? Could a dealership tell if I installed a converter if they did basic warranty repairs?
Should I wait for my warranty to expire before putting in the Yank?

Re: can't decide which converter?
OK,
Here's the deal on torque converters for Trucks.
Yank Truck Thruster 2600/3000 converters:
They are large converters with lots of towing capacity. At 278mm (11"), they are smaller and lighter than the stock 300mm (12")converters, but keep in mind, this is the same size converter that comes in the Chevy Trailblazer. Trailblazers can tow quite a bit. That's why the towing rating for these converters is very high. I have the Truck Thruster 3000 in my Tahoe. It gave a HUGE increase of thrust off the starting line. My 60' times dropped from 2.5-2.6's down to 2.1s. My quarter mile times dropped 6-7 tenths. The only place these converters help is off the starting line. The shift extension is only 100-200 rpms higher than stock. In normal driving, you will not feel much of a difference over stock except from a dead stop. This is where the Yank TT3000 is superior in a big way over stock. Racing from a roll, it's not that much different over stock.
Stepping up to a smaller 258mm (10") converter like a Pro Yank 3400 (3200 in a 5.3) or a Pro Yank 3600 (3400 in a 5.3), you will not only gain a little in stall speed, but you will gain valuable shift extension...especially with the PY3600. However, the more shift extension you have, the looser the converter's going to feel...especially in a heavier vehicle like my Tahoe. Towing capacity with a 10" clutch is decent...around 4,000 lbs.
The small 245mm (9.5") converters are best suited for lighter regular cab Silverados or heavier vehicles running heads/cam. They will stall higher and have even higher shift extension. For example, the Vig 3200 will stall around 3500-3600 behind a 5.3 and will extend shifts to about 4500 rpms (like after a 1-2 shift). This is good for maximum ET, but it will feel much looser, the heavier the truck. Precision runs a 9.0" clutch in their Vig 3200. I wouldn't expect to tow more than 2000 lbs with a clutch this small. A Yank Super Stock 3600 (stalls 3400 behind a 5.3) has the larger 258mm (10") clutch like in the Pro Yanks. Because of that, it will tow closer to 4,000 lbs. When in doubt on towing, go with the larger converters. Your tranny and converter will thank you.

Re: can't decide which converter?
You would get about 2800 rpm stall with a stock Trailblazer converter behind a 6.0L. It would drop your 1/4 mile times about 3-4 tenths vs. stock. A nice gain with good drivability. It would seem very close to stock except for off the line. Trouble is getting a good price on a new Trailblazer converter from a dealer. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

Re: can't decide which converter?
If you're going to tow 7,000 lbs, don't get anything smaller (in diameter) than the Yank Truck Thruster 2600-3000. These 278mm converters have the bigger clutches needed for this kind of towing duty. A re-stalled stock converter is always an option, but it's hard to get more than 2400 stall behind a 5.3 without losing a lot of efficiency...that's where the smaller Trailblazer type of converters work well (like the Yank Truck Thrusters).
