03 denali with ls2 needs stronger transmission

[t_ahan]

ok so here it is! i have an 03 denali with ls2 heads and slightly bigger cam shaft w/ratio ultra gold rockers and an lsxr intake manifold with few other power adders and i have heavy a** SS replica 22in wheels that dont help my trans...my transmission finaly went out after 6months of driving with only first and fourth gear!! so i am lookin for a stronger unit but only found these- performa built, monster transmission, finish line transmissions, performance automotive and transmission center, and then a slightly better than stock rebuilt unit from ronnie smith transmissions... i have done way too much reading and have found pretty much jus as many good things about each vender as i read bad things...i would like to hear what every recommends b4 i pull the triger and end up doin a trans r&r 4 times in 12months!! btw i abuse the truck really ******* the street but def wanna have something i can finally go to the track safely and see what kinda numbers i get b4 i super charge the truck in a year or so...

We have an RPM Level 6 in the SSS, handling over 600HP

a level 6 should be able to handle at least 700 shouldnt it??

 

[t_ahan]

level 6!!!

well i must say i have never known anybody to have an RPM trans but i def trust u and your expeirence!!! not so sure that i need level 6 unless u think it would last long enough till i get my money back up and s/c the truck..any issues with that trans and how many miles u have on that level 6 ...ps do u daily drive the tbss! thnks

slap an 80E in there

slap an 80E in there

not worth the fabbing. easier to get a RPM tranny and be done. if you get an 80e, its still a stock tranny

 

[t_ahan]

which rpm?

which rpm trans u think would be strong enough with out goin level 6 or will that be worth the extra money really?i dont want to have to replace the trans agian in 50k ..and will thier unit work fine with my diablo tuner that i use to adjust line pressure shift points etc

 

[waxworkz]

depends on you, price is relevant. if you got the money go bigger than you need now, so you wont have to upgrade later. how much power you gonna end with? i'd be looking at a custom tune, instead of that hand held tuner.

inthe end

in the end i goin for a 550hp motor but i dont kno what that would be after goin through the transfer case then to all 4 heavy ass 22's

 

[waxworkz]

i think a level VI would be plenty for 550hp. just invest in a good convertor and maybe re-gear depending on what you have now.
