ford aod/4stb ???
ford aod/4stb ??? I contacted a local builder (freddy brown) about a built 4l80e, and he told me the 4stb is a verystrong tranny with OD and manual valvebody and T-brake, he has a nice price on a built one with an ultrabell bellhousing to mate it up to the ls1
Does anybody have any experience with this tranny, i cant find anything with good info on her

Damn that shop had me phsyced i thought i finally found a 4speed auto with transbrake that could handle power for a decent price
Lol, now im in the same place as b4, depressed about the price of those damn 4l80e's lol..i keep thinkin maybe ill just go TH400 but then remember what it was like with the th350 and why i got rid of it

just a fyi as recovering mustang addict the trans of choice for big power in ford circles was always built c4's they are supposed to be the simplest and easiest to make bullet proof. the c6 might compare, i saw alot of people who liked those. personally i would do a t56 from hell, i forget what kit it was for the t5 that was supposed to be good to 600ft lbs of torque!!
heres one but it wasnt the g-force that i was thinkn of but im sure they have kits for the t56 and you already have a t56 right??

Ya i called them about doin a 4l80e which they build them as well so i didnt take them as gaining a customer by selling me the aod since they do both trannies
But ya i have a t56 and wanna go auto because im boosted now and im gonna shoot for low 9's atleast so the auto will allow me to be much faster

The AOD's are an excellent transmission, but in stock form they had the torque converter lock to the 3rd gear input shaft. This would cause the bog and "no more torque multiplication", which would "kill" performance. When the AODE was introduced, it was like the 4L60E using a clutch now in the torque converter. When I used to build these AOD's we would go with a Continental 10" non-lock style torque converter and this would make the transmission come alive. You could also change the gear ratios easily to a 4R70W style which would change the first ratio from 2.40 to 2.84 which would help some with the 302ci. motors. Contrary to popular opinion these transmissions eat up very little in terms of horsepower. They have one planetary & no low/reverse clutches to eat any horsepower. The C-4 and the Torqueflite 904 are very good at not eating any horsepower either. The C-6 eats a lot of horsepower mainly due to the very large low/reverse clutches that are used in them. The AODE eats less horsepower than the 4L60E. But switching to another transmission is very expensive to get a few horsepower. If you are looking to drag race a 3 speed automatic behind a Chevy motor, then go with the Torqueflite 904. They came in mail trucks for years and have the Chevy V-8 bolt pattern. You can install the 2.74 or the 2.45 gear set in these (both gear sets were common) and they are cheap to build and are very reliable and eat less horsepower than the TH350, (again no low/reverse clutches).

I know this is an old post but FB's 4STB will handle it no problem, I know Freddy and some of the cars he has them in and 800hp is no problem. The trans is also around 100lbs lighter than a 4L80e and smaller, no tunnel problems with it at all. I was looking at a 4L80e but the 4STB make so much more sense.

It was way to tight.I talked to Joe @ ProTorque and ordered a 8" 5000 converter directly from them. It put my 60's back in the high 1.4's to 1.5's, but the tranny would overheat easily. I went with a bigger cooler with a fan and am still having overheating problems. Which made non daily drivable and 4th gear unusable.
So now the car has basically turned into a trailered car which I did not want. Reciently I had the converter restalled to a 5500 hoping to get the 60's into the low 1.4's, but i haven't taken it to the track yet because I don't have a trailer.
Once I borrow a trailer and take it to the track it better 60' in the low 1.4's or the transmission is coming out. Then I will have to make the decision on a TH400 & trailer or going with a 4l80e and driving again.
Don't get me wrong it has been a very strong reliable transmission, but with it being non-lockup daily driving is anoying. If you are looking for a track-only tranny go with a 3 speed TH350-TH400. If you want a strong track/street tranny go with a 4l80e.
Sorry for the long post, but I wanted people to know my experience with the 4STB AOD transmission.
If anyone wants to buy it please shoot me a PM.

They told me you loose lock-up with the 4STB. Look where it says here "solid 300M (non-lockup) input shaft. Please show me wher they have a lockup option.

He does do it with a brake but I see with a 8" 5500 converter it could be tricky.
I am guessing it's 178 lbs without the converter by what Jake is saying and I am sure he would be correct on that, I had seen 225-250, sorry , probably with converter. I'll have to check the 4STB directly with FB, the numbers on the net are with and without converter some stock I can't seem to find a definite number.

An AOD or 4R70 is about the same weight as a 4L60 platform.
130-140 lbs.
I feel the 4R70 has more potential power capacity than the 4L60 series but nowhere near the 4L80.
$2200 for a 4L80 with transbrake is pretty fair IMO.
