I've seen alot of different stall-speeds on here from people with 4L80e's....I'm just curious here if it's the motor that is affecting the stall or if GM snuck in a few different converters without telling us

I stall to 2100rpms, I know moregrip stalls to 2500 or so.....

 

yes, for my 03 1500HD and my 05 2500HD, stock, I brake and flashed at 2500rpms, now I'm considerably lower on the brake stall due to traction. I would guess your right. btw

 

I am the same as moregrip with the '03 1500HD. No surprise there. If I don't hold the brake down hard it seems I start to spin the rears.

 

I can only seem to brake stall mine to about 1500-1600 rpms before it starts pulling hard. I think its time to get a 3000 stall
