What was the stall speed on that converter? I'd go with a new 2500 JMBX for my 6L80, but I want a slightly higher speed to better match the cam I'm installing.

??????
Whatever STOCK is I guess

Gotcha. Thanks.

Contact your cam manufacturer and they will recommend a stall speed range based on the cam grind, vehicle weight, intended usage pattern and final drive ratio. That is the best way to determine the appropriate stall. You want your converter to be "matched" to your cam and where it makes a preponderance of it's power.

Billet cover if you frequently tow/haul or otherwise live in a high heat climate. Make sure the new converter has a converter clutch that's at least .050" thick (my builder uses .070" thick clutches).

If the Delco reman uses the same garbage .020" thick clutch, hard pass.

Sorry to dig up an old thread. I just had a question in regard to the clutch pack thickness.

This is quoted from the sales rep. This particular Converter also has a billet front cover plate.

I had asked him about the thickness, and this is what he said. He also sent me a link from Sonnax.

"We utilize a new woven carbon lockup clutch in these builds. It's the exact material that would have come stock. Same thickness as OEM"

What are your thoughts on this? Stock thickness but a better material sounds good, I think.
Does your guy build them with billet front plates?

Thanks

So is replacing the TC easy like removing the old one and placing the new one into the transmission? I too have the same issue as the original poster and I wanted to replace my TC as a PM thing before it goes out since the trans will be removed to replace the rear main seal.

yes it's easy once the tranny is out.

The Sonnax woven carbon friction with the billet front cover plate will give a longer live and perform like OEM. I would have no issue with a torque converter rebuild with that clutch, especially for a stock replacement.

Sonnax also sells the Borg-Warner high energy frictions as well, which some rebuilders prefer. The HTS friction is the best for TCC slip in the stock application and comes in 1.1mm and 1.7mm. Even though this is a high quality friction, I don't think it can compete with the woven carbon (unless you disable TCC slip), so many prefer the thicker version, because it will wear over time, and more friction equals more life.

Thank you MWD_CTSV, I appreciate the input and info. This converter sounds like a good option for me.
