Yank 3600 driveability???
 

I just ordered the yank SS 3600 stall for my 5.3 GMC Sierra 2012. The truck has LT's 4.10 gears and a tune. How is the driveability of the truck going to be like with the yank SS 3600 on it? The truck also already has a true kool 40k transmission cooler. I will be adding a 228/228 cam to it in a couple of months but wanted to throw in the Torque converter in first. https://cimg5.ibsrv.net/gimg/www.per...f5aa49f5c6.jpg

In your truck it would be fine. In something heavier I wouldn't want to deal with it.

In my xcab (gmt800), I love my 3800. It's an fti stall, single disk.

My Yank 3400 is super tight in my setup. Been planning on send g it back to have it loosened up. I think you will like it for sure. Mine acts great around town, really nice to drive, just a bit tight

What do u mean by it being tight?

Stock converters are "tighter" than performance converters, so they begin to transfer power at a lower rpm. "Tighter" indicating that you don't have to spin them as much to move the truck. It's good for street use where it doesn't feel like you have to use half throttle to move the car. For a more performance or racing application where launching is of a greater priority than rolling casually off a stoplight, a "looser" torque converter allows the engine to build a greater RPM before transferring power to the wheels.

Random questions =

1. What stall would be ideal for an SUV? Specifically 07 Tahoe PPV which weighs in at a hefty 5200lbs +. I was thinking 3400. My previous 99 Tahoe had a Yank 3200 and was great. That weighed about 4600lbs and also had a built trans it.

I have an FTI 2800/3000 in it now.
Reading about loose and tight in regards to converters a bulb just went off in my head in regards to mine. It lunges like crazy with very light throttle, not all the time but more often than not. To a point where my wife wont drive it. And almost hitting people in front of me at stop lights, parking lots. I'm kinda used to it now, its been going on for so long. I went over it with my tuner but, he couldn't find anything out of the ordinary.

2. Could this be that the converter is too tight?

That is a tight converter. My FTI 3800 is loooooose.

I had originally wanted a higher stall but the shop convinced me to go lower.
I may contact FTI to see if they could re-stall it to ? What?
I liked my 3200 Yank, it was awesome. But, it was a lighter SUV.
What would be the desired stall for something so heavy? Daily driver.

Thanks

I would recommend driving a vehicle with a loose stall. Some people don't like them while others love them.

If you do go higher and looser, you'll need a new separator plate with different hole sizes.

Loose converters take more pedal to get going.

Call FTI and talk to Dalton. Tell him Jessie sent ya. Lol.
