Kinda o stupid question but what transmission is my 2002 Sierra have it is a automatic with the 4.8 and 2 wheel drive. thanks I'm looking for a convertor for it and just need to start somewere thanks.

 

4L60E. I would contact one of our sponsors on the right. ---->

Either Circle D or Yank. Can't go wrong with either.


Look into upgrading your trans cooler also. It will runner warmer with a stall.




Be careful, it is addicting & expensive.

 

all depends on what your plans are for the truck, weekend warrior, street truck...

 

will run good with a ls6 cam/springs(hint,hint) but should be a 4l60e

 

thanks all and what stall convertor would go good with this ls6 cam and spring : ) it is going to be a weekend warrier want it to run 13's and maybe 12's later down the road with either a turbo or 150 shot. what stall do they have stock?

 

extended cab? single cab? want to hit 12s? that ls6 cam isnt gonna do it.. and ur looking at a 3600 stall to even try to hit 12s... and if its an extended cab i dont c many hopes of it doing it na... with a 3600 stall and a 220 duration cam might get u ur weekend warrior but idk about 12s.. atleast not on an extended cab.. dont want to be mean just letting u know this modding thing isnt cheap and easy.. u will need full bolt ons and probably a built tranny... goodluck..

 

regular cab and I am looking at 12's with a turbo or a 100-150 shot of nitrous as stated LOL I know it's not cheap I mod every vechicle I have ever owned even the shitty little 4 bangers I bought to try to save gas cause my other car was a modded v-8 LOL. Just not t familar with my truck yet so looking for suggestions and idea's. I would think with a convertor,CAI, Headers, and a turbo or a 100-150 shot thisthing should be in the high 12's at least I would hope that is were it should be correct me if I have the wrong idea please. I did run a Ford Lighting on the way home from work the other day and I pulledaway from him pretty good from 80 to about 115 mph he couldnt catch me and all I have so far id CAI and a 87 performance can tune from my handheld tuner LOL.

 

what a relief.. yea no problem then.. i thought u wanted to do it NA.. lol.. well if u plan on going turbo or on a shot make sure u let who ever u get the converter from know.. that makes a big difference on what they will recommend.. and then go from there.. cam is different and everything is different then NA.. make sure what ever u decide to do is what u call and let people know.. i cant help much because im NA.. all i now is that u need i wide lsa and may b a lock up converter if u plan on squezing.. lol .. hope other chime in..

 

How do you use the truck? With a 4.8L I would go big, like 4000 rpm stall torque converter. 4.8's have enough power to run good times, it's just hard getting them out of the hole fast enough.

 

I use the truck as a Daily Driver and drive it roughly 35 miles on the highway a day. this is all great info keep it coming guys thanks you
