I just installed my circle-d converter about 5 or 6 months ago, and as many of you know it was a really loose converter (3800-4000 stall speed). Well as I've put miles on it, it has progressively gotten tighter and tighter. It is still pretty damn loose, but I have not been able to brake stall it near as high, and it doesn't seem to flash as high driving it. I took off from a stop sign in 2nd gear today to see what it'd flash to and it only went to ~3500 RPMs.

Is this normal, or do I need to have it split open and checked out?

 

i have a edge converter that has seemed to be getting tighter on me as well but i have not brake stalled it to see where it is at. its been about a month for me

 

I wonder if the fins in the converter start to bend a little bit over time? (If that would even cause what youre talking about...not sure)

 

Are you sure it's getting tighter and you're not just getting used to the rpms?

 

I'm pretty sure, it felt a little looser today driving it so IDK
haha

My truck is weird.

 

Maybe you're wearing out your engine running it up to red line so many times and losing torque.

 

Put 500 miles on mine and it still does what it's supposed to do.

I just think your truck is weird
