Any estimates on how long should the stage V FLP trans last under the following:
450rwhp
425rwlb-ft
4400stall,2.78str
3.89 gears
slicks, no traction issues...launching hard
proper cooling (under 200 degrees)

(I got my assembly manual/video for 4L60E...enough said)

 

I can't say for that setup, but for mine:

~350rwhp
3500 stall w/ 1.61 STR
3.23 gears
175-190* temps depending on weather
Street tires, mostly street driven with few launches, but a decent amount of WOT from-a-roll downshifts

I expect mine to last well past 50K. There are a couple people on here making some serious power with big motors both NA and n2o that have around or over 20K miles plus track time without an issue. Also some FI cars with decent miles & track time seem do be doing fine. These are Level IV trans' too, not too many people have the Level V yet.....

 

Thanks!
