ok yea, i think you guys have really shown me the light on the 4l80-e. I'm going to have to do some more research and saving but it seems like a solid choice.... keep the input coming!

I'll tell ya what I did....and would do it again in a full weight car (All AC, pw,pb,pdl,etc,etc 3811lbs with me in it)....Rossler T400 with 3.08 rear gear with a transbrake....best of all worlds....don't need overdrive with the 3.08. On the TB it sixty's 1.35 to 1.42....runs nines at 141mph....and cruises easy on the 4 lane. Just be sure to get a tight 10.5 inch torque converter like a 2600 stall Vig.

I agree......

Myself im going to stick with my new gears... 3.54's with a 28" Tall street tire and sooner or later go with a Gear Vendor OD Unit...... OD is the only thing i miss....
Now i think adding the GV would be awsome and the best of both worlds....
I went with a Glide per Carl Rossler.... Easier to launch with a 1.80 first gear and with the massive TQ of a Turbo Car the 1.8-1:1 fall off on the shift isnt much.......

Price everything up and set them side by side on paper.....
A Manual Valve Body is awsome.... You shift when you want... with out having to push in a clutch LOL

Thats my .02

Well this is my input. If you want to race you might want to consider the Auto. For one with manual I found out the hard way you can't build boost very easy on take off. With Auto you stall it up and it builds boost. Just my input.

My 4l80 runs great. Of course you have to get use to a manual valve body but its like having a m6 car with no pedal to push in So far I am very happy with the 4l80 and having the overdrive was a plus in my book. But different strokes for different folks. Swapped from a M6 and was tired of breaking so called high performance clutches and custom shafts etc

is your 4l80e full manual? if it is, who built it?

why are you set on TT? is it a braggin thing, single turbo can do more then double your goals. also why isnt there a stall in the th 400 option like there is for the 4l60-e

I had my buddie build it. I named his bullet proof 4l80 the gator Because hes a redneck and builds swamp buggies We used all the top builders goodies in it. Should be rated to 1200 hp Full as in you have to put it in every gear? Yes! Then I wired up a slick relay system that I arm for overdrive to kick in when needed

that's a nice sounding setup. I would love to have the added stregnth of the 4L80E in my 00 Z28 shop car. I just don't see spending the $3000 I did last time. I could dell my Century built 4L60E and vig verter and cover the cost of the TH400 swap. the 3.08 gear would help load the turbo and keep the revs down on the highway too. oh well. decisions, decisions.

I have a built t-56 that can probably take on well past 700rwhp...harsh power at that. All new billet keys/slider/blockers/shift forks...ect...ect.

Also have a Rock-On Stage IV manual valve-body vaccum modulated 4l60 (non-electric) that is amazing on the street and hits even harder on the track off the footbrake. Wish I would have opted for the 4L80. I would have it with the same setup.

I voted for the Turbo 400. Strong transmission for hard hitting power.

Get the TH400 and forget about problems. I have a T-88 car and two pumpkins for the 9-inch: 3.90s for the track and 3.08s for the street. It takes 30 minutes to swap the pumpkins and I re-use the lube. Simple stuff, cheaper than ANY 4L80E, and runs great on the street with the higher gears.

BTW - one guy said you had to modify the car for a TH400. WRONG! Mine bolted right up. Now the 4L80E is a different story...

dow you know what your 60's are for the 3.08s compared to the 3.90s?

pretty good if Onfire can get 1.35's with the 3.08s i might switch to those

if you think a 4l60e will hold up to a pair of twin 60's youre nuts. not for for long at least.

do the 80. if youre cheap do the 400, and see how much you enjoy losing OD and lockup.

80's goin in my camaro, no hacking needed. stock pcm will control the 80 with modifications to the pcm from HPTuners, it will tune like a normal pcm. search button is amazing. use it.

iTrader: (19)

no, its not a different story, its the same story.

I am curious what you paid for the center section for your rear? I am trying to pick a rear end gear for my M6 car, i plan on FI in the future but i want 4.11's till then. What made u buy the extra pumpkin?
Anybody? 3.08,3.50...what gear ratio for turbo? 4.11's would suck even with a small shot of NOS outta hole?

SS00Blue

Smokin: Long time no hear. I hope things are going well for you. As for the 60's, I don't know, because it's on the street. I imagine it's slower, but in Detroit, Texas, or Ohio for that matter, the combo works OK. It's all in the combo because torque moves the fat.

CamaroZach: I am not sure what you mean, but I replaced the trans crossmember and that's all that was needed to do the TH400. Come see if you don't believe. The 4L80Eis MUCH larger, and I'm going from info on your own site from the transmission section, as I have not done that particular swap. I AM using BS3, though... Any thoughts?

For the previous poster (because I don't understand the UID): I got a nodular iron aftermarket center-section, with gears, set up by me, for $300. Easy set-up, easy install. I'll set up a pumpkin for free for any LS1tech member, if they pay the freight, and ship the new parts to me. After that, it's just a matter of torquing a few bolts.

OBTW: I bought the extra center for the reason that I want to destroy bolt-on Cobra ******.

for th e4l80e swap, it will slide right in with the need of a new crossmember, just like the th400. The 400 is shorter in overall lenght, but you will NOT HAVE TO TEAR your car up to get a 4l80e to fit. Its really a no brainer.

is you have a 99+ PCM, consider yourself really luck since you can have your stock pcm unning software modeled with a 4l80e parameters... easy!! You tune your 4l80e just like you would tune your 60e.

Now, for use bloks that have the ever-tuneable 98 pcm, well, you either have three choices if you want to go electric. Swap to a 99+ pcm with harness and possible sensor swap, add a TCI trans box to controll the trans only (just like hptuners for example, no extra learning curve necessary, or which is what im doing, go with a BS3, to not only control your engine, but also control your 4l80e.

also, with the 4l80e, i believe you dont have the inherited problems when shifting WOT into 4th gear (od) therefore, you can gear your rear a bit higher, possibly aidinf your sixties and using th full spectrum of the 80e' gearing.

laterZ!

I wasn't suggesting that he would "HAVE TO TEAR" his car up, but I have one question: Was there any modification of the sheetmetal? The swap threads in the Trans section seem to suggest that a sledge is required for clearance. I could be wrong, though.

None with my TH400.

as i wasn't suggesting that you implied that. My implications were to superman, who feared that a 4l80e swap would require "hacking" Which of course isn't necessarily true. Thus, i was just proving that to get a 4l80e, mod wise, is not as involved as anyone might think.

However, if your imply that a simple BFH mod, like the one that is needed to fit 315, is enough to make you choose between these two trans, then, well, i believe we are completely different people with different levels of mojo.

Its our choice, we should be all wise enough to scale the differences and make and educated decision. I felt that the 4l80e is a wise trans choice, as you feel the th400 is.... but to say that one is "better" than the other becuz it will not require you to actually lift a rubber mallet and massage your trans tunnel a bit, besides your other points you had mention which i do agree with and see your point, well; to me, that isn't a viable difference that will weigh enough to tip the scales. IMO of course!

Crap I am thinking about swapping out the 4L60E for a TH400 and 3.08 gears. Mine is mostly a street strip car. What verter are you guys using with your TH400's?
