Since my transmission is definitely going to be rebuilt now I want to install a Yank converter. How does the Yank operate versus the stock converter? I don't need the performance numbers, I'm just curious about from a stop, once you let off the brake, does the vehicle start moving like with the stock converter or do you have to get the rpms up to 2600 before you even start to move? How streetable is it? When I'm tooling around town is the truck going to be revving up to 2600 all the time for me to go anywhere? I know most of you are going to say "go with a 3000 stall, you'll wish you would have" but keep in mind that I hit the dragstrip next to never and daily drive this truck. Thanks for any insight you can offer.

 

The 2600 is barely noticable. No you wont be reving around town. In order to get to that RPM you will have to brake stall.

 

So the stall ratings are for brake stalling only? That means that even with a 3000rpm stall when I'm sitting at a stop and then let off the brake and accelerate to get moving it doesn't climb to 3000 before I go anywhere? I'm still learning the whole torque converter thing. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

You will notice the 2600, but you will get used to it pretty fast. I think the 2600 is what GM should have put in these trucks from the factory.

 

It sounds like a higher stall converter might work for my 03., but first a few questions.

I tow a car or boat every once and a while so how would a 2600 or 2800 converter work with towing?

Like the previous posted question, If I am at a stop and gas it (not hard) does the engine have to spin to 2600 or 2800 to get moving? If thats the case wouldnt the truck be launching hard all the time?

Is there really a big difference between a 2600 and 2800, since there is only a 200 rpm difference?

One last question, would this void my tranny warranty?

Does anyone know what the converter sizes/setup are for a factory sports truck, like a Ford POS Lightning?

I know i just threw up a bunch of questions but I would appreciate the info since I am interested in any mod that can drop some time off my acceleration times.

 

I run a Yank3000 with no drivability problems.When you step on the gas, it revs to 3000rpm instantly and you take off, you don't feel like it is slipping you just take off higher in the engine's powerband.I assume the 2600 would be the same with a lower rpm takeoff.I highly recommend the Yank3000 as you still get full towing capacity and are 500rpm further into the powerband and get more torque multiplacation.

 

Sounds like a 3000 would be cool. So is that a yank 3000? Is there a special name or other model number I need to know since I want a converter that can tow?

Also I still need to know about the warranty issue. I would assume a new converter would void the tranny warranty, correct?

 

Lets clear up a little confusion here:

Assume we are talking a 3000 stall. You can lightly throttle the vehicle and it will take off like normal (not 3000 rpms). With a mid throttle take off, rpms may be near 2000 rpms - noticeable difference, but not bad. A hard take off makes the converter flash to its stall speed of 3000 rpms. You don not have to have power take-offs from every start.

Its kinda funny - there is this little fuzzy area in the rpm range of 2000 - 2500 rpms of my Yank 3000. If I have light acceleration and the truck is moving, then move it to mid throttle, rpms may climb up to 2500 but the truck doesn't immediately respond to the throttle increase. If I make rpms come closer to the 3000 range, I feel the torque increase, but if I leave it in the 2500 range, it will slowly catch up. I assume this is the "looseness" that people with big stalls have.

I was always under the assumption that you had to hit the 3000rpm before the truck even started moving. I think I might look a little more seriously at the Yank 3000 now.

 

Yea that definitely helps answer my question too! Now I NEED to get one, probably a 3000 if possible. So now the question is should I go with a Yank or Vig 3000? I need to be able to tow at least 3500-4500lbs.

I still need to also find out about warranty issues, that is if anyone knows.
