As you cannot change the internal gearing of a 4L80E, other options that you have brought will not be discussed at this point.

Will be calling Jakes Trans. tmmr and get some more opinions on it, thanks guys.

Jake in Texas? You'll be buying a 4L80E from him. Tell him I said hello lol

LTb1ow 01-29-2012 04:56 PM
Yes, that is what WBT mentioned you would say.

True, but 700 hp is not out of the question with an auto.

Which is why the trans in question is rated to 750hp which I assume is rwhp.. :wink:

Fastbird also has pretty nice heads on his motor

It is not yet proving to be a good retrofit trans for the masses.
False.. can run the 4l80e based 6spd by TCI w/controller, Also can run a gm 6l80e with a bit of wiring/pcm & correct tuner for the job.

Has been installed in 4th gens, 5th gens,GTOs, full size trucks & vettes....

LTb1ow 01-29-2012 05:26 PM
While double OD would be sweet, this is not a race car nor is it a rich guys baller build. So 4L80E will be a nice compromise.

BonzoHansen 01-29-2012 05:26 PM
Very bold of you lol. Well, the 4L80E TCI trans is not a 6L80E. I stand corrected and will add better adjectives for the nit picking crowd: there is no dedicated 6L80E stand alone controller yet.

Yea, it's in a 5th gen, BFD. Of course, GM put them. Trucks are high off the ground. I've seen them in 1st & 2nd gens, they hang quite low and are tall requiring basically a new tunnel. IMO a street car in NJ the lowest point in the car should not be a trans pan. And if it is not a street car then a 6L80E is a bad choice IMO. YMMV.

I am 98% sure the BS3 & AEM setup will control the 6l80e, but they are not dedicated, just able along with running everything else. (again, steering towards the rich man baller builds)

Okay...now I will agree with you. lol


p.s. I did say..... "4l80e based 6spd". Its their answer to the guys wanting a 6l80e. And a poor one at that due to the issues I have personally seen with them.

BonzoHansen 01-29-2012 07:07 PM
Lol. Yeah I don't hear good on them either and the price is high. Go 4L80E and gear vendors. 8 speed!!!!!!!

Say what?

That would be a 5 speed...?

BonzoHansen 01-29-2012 07:46 PM
:facepalm:

go find out how gv works.

LMFAO..... to the last two posts.

Th400 is lighter than a 4l......

As a Th350 is lighter than a Th400, as a ten bolt is lighter than any aftermarket rear end, as a LS1 is lighter than n LT1, as any stock suspension piece sans K is lighter than aftermarkert, must I go on?

Whats your point?

sweetbmxrider 01-30-2012 08:38 AM
Lighter and stronger hence faster and more reliable. Don't apples to oranges me pal. Better gear ratios too so it would be quicker.

4L80 and TH400 have the same ratios save 4th.

more power overcomes a few pounds. and being a tenth faster is diminished if the car is no fun to drive except at the track.
4L80E is essentailly a TH400 with 4th gear so I'd not be anymore concerned with reliability over a TH400.

sweetbmxrider 01-30-2012 09:37 AM
It definitely isn't a few pounds. He also has to botch up the car and hope it can be tuned to work properly along with a new converter. Not my money though so I'd gladly spend it towards an 80

WildBillyT 01-30-2012 09:42 AM
4L80 is 35 lbs heavier.

Adam, to your last point, and I'm not trying to be an a-hole, but if the retrofitting and such will lead to a botch job I'd stick with the TH400 and 3.08s. No shame it tapping out- I had to do it on a big project.

sweetbmxrider 01-30-2012 09:49 AM
I thought the weight was more than that. Its been a while since I looked into the swap so I guess my facts are wrong. Matt knows his choices and what he wants the car to do, should be an easy pick.

S.J.SLEEPER 01-30-2012 11:13 AM
I thought it was a 75lb difference...but maybe i was thinking of 6l80 since thats on my mind.

LTb1ow 01-30-2012 11:17 AM
I know the choices but want opinions on the matter. Not a small chunk of change to blow and end up hating driving the car.

Basically I have no idea WTF I am doing

I measured a TH350, TH400, and 4L80E all on the same scale on the same day.

Weights were

TH350 short tail- 125 lbs.
TH400- 134 lbs.
4L80E- 178 lbs.

A TH400 DOES NOT weight 30 lbs more. You are hearing that from the "internet experts" that likely couldn't identify the difference between a TH350 and TH400 if both were sitting side by side.
Once ONE idiot says it on the internet it becomes fact. Like a TH400 consuming xx more HP than a TH350 etc..
A TH400 is about 10 lbs heavier and the 10 lbs is in the rotating weight. Mostly the planetary sets.
He says about ~45 but the '80 was not a fresh rebuild.
