Torque converter stall?

Recommended Posts

I'm at a loss for what stall of converter to go with in my truck. I'll be dropping in an lq9 6.0l I got from an 06 escalade soon and feel like I should replace the torque converter and up the stall a bit. Monster trans sais the stock stall speed in my truck is 1650 rpm. any help would be great. trans is a built ss monster 4l65e, 4:10 gears, turning 35s. Not trying to win races, just need it to pull my camper nicely, work well off road, not a daily driven truck, but does still see a fair bit of highway driving. Any ideas?

I'm just here to ask for a build thread with plenty of details and pictures! :)

Think if you plan on camming it, nothing less than a 3k stall.

With towing, high stall is bad.

X3 on this.

 

One thing you may consider doing is replacing the stock flex plate with a race grade SF29 unit, if you are towing, you will NEVER have to worry about flex plate cracks.

 

The race plates come with longer bolts to compensate for the increased thickness of the plate.

If you get a stall converter go for about 2800 if youre going to tow. Also spend the money on a multi disk

Thanks guys, lots of good info here. I'm going low stall for sure for towing. If I do decide to cam it it won't be for a while. I go pick up the engine saturday, I'll be sure to take a bunch of pics and start up a build thread.

If you stall at all go with aftermarket trans cooler. A lot of guys like the TruCool 40k. I like the setup I put on. It costs more, but my trans has been alive a lot longer than it should have

Regular z71 external cooler not up to the job?

The SS guys have the same cooler as the z71. Most of them guys get rid of that tiny cooler. My first cooler was larger than the KNP code cooler, and I still went larger.

Just looked up the trucool 40k. It's like 4x the size.

A comparison

Installed on a Silverado SS

A stall converter causes the trans to run hotter. Keep in mind that tiny cooler was designed to work on a "stock" application
