ryan_310 Posted March 15, 2009 Report Share Posted March 15, 2009 I have been trying to do some research on how much power a stock tranny will take but i have been unsucessful. I want to go forced induction but havent decided if i want supercharger, procharger, or turbo yet. If anyone could help me with the transmission piece it would be alot of help.

F1SSS Posted March 15, 2009 Report Share Posted March 15, 2009 From what I have learned on this site, basically if you add a FI kit you will need to beef up your tranny. I spoke to my dealership awhile ago and they were saying anything more than 450-500hp then you will have safeguard the tranny (then again, that is the dealership). I am sure some more knowledgable people will tune in from the site. Just info I know off the top of my head (my truck is not being modded). If you want a Procharger there is a member Sick03ss that had one for sale, not sure if its still around or if it's on ebay. Quote Link to comment Share on other sites More sharing options...
sonickoolten Posted March 15, 2009 Report Share Posted March 15, 2009 ^^ i think hes still sellin it..... but yea the tranny is the weakest link in our trucks ur gonna have to beef it up.... i would go with the 4l80e...... Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted March 16, 2009 Report Share Posted March 16, 2009 Many here including myself have had some misfortune even on a near stock truck, make sure to beef your trans up first.... Quote Link to comment Share on other sites More sharing options...
ryan_310 Posted March 16, 2009 Author Report Share Posted March 16, 2009 Looks like i will have to go with the 4l80e tranny, 3000 stall converter, and shift kit. How about the transfer cases do those hold up through alot? Quote Link to comment Share on other sites More sharing options...
F1SSS Posted March 16, 2009 Report Share Posted March 16, 2009 your t-case just splits the power, no mods as far as I know are required for that. Just make sure you do proper maintenance on it. Dont know what milage you are at, but I did a t-case service along with my tranny service flush at 50k to prolong the life of the entire system.

Unless you either run it untill its dead, or build it for a specific reason or application in the first place. Get your goals and wants figured out first, then purchase your mods would be my opinion. Good luck Quote Link to comment Share on other sites More sharing options...
got vortec Posted March 20, 2009 Report Share Posted March 20, 2009 (edited) not trying to jack yer thread but the sss comes with the 4l65e correct? whats the difference between that and the 4l80e? ok so in the stall converter whats the number mean ..ex 3000 ,2800 whats all that mean? thanx Edited March 20, 2009 by got vortec (see edit history) Quote Link to comment Share on other sites More sharing options...

The 4L80E is a sweet tranny but its pretty expensive more for race applications. The stall converter number mean that when you hold the break and gas at the same time how many rps the engine can rev before it will engauge with the transmission.

The stall converter number mean that when you hold the break and gas at the same time how many rps the engine can rev before it will engauge with the transmission. The SSS is equipped with a 4L65E not a 4L60E, but they are almost the same thing. The 4L65E has some hardened parts among a few other things that the 60E doesn't have. The 4L80E is a heavy duty transmission out of the 3/4 and 1 ton truck line, it has much larger/taller gear sets the the 65E and can take a ton more abuse. Many guys are actually doing the swap now, but it is very costly and requires some fabrication to make it work. Stall speed is what RPM the converter can flash to before the vehicle will move.....typically a higher stall TC will keep you higher into the power band when shifting during WOT also.......

SSThunder Posted March 21, 2009 Report Share Posted March 21, 2009 I've got a ton of mods and FI is one of them and the only trans upgrades I have done is added a zippy shift kit/servo setup and a Trailblazer TC(TBTC) My SS runs 12's in track form and has been boosted for around 30K miles or so. I don't tow or haul so the TBTC is fine for me. Set your goals and make a plan of how you want to get there. If you want low 12's expect to get a built trans. I'm not there yet and I'm happy with my SS right now but I would like to shoot for low 12's high 11's. I just don't feel like putting another $3K into her right now as the rear end also needs some upgrades. Quote Link to comment Share on other sites More sharing options...
got vortec Posted March 21, 2009 Report Share Posted March 21, 2009 (edited) as soon as i get one im going to shoot for high 11's..i have an amazing transmission guy who will hook me up doing the labor and shit how much fabrication r we talking?
