Carbureted LSX forum - Carbed LS1 + 4L60E possible?

Hello all, I've been all over the internet researching how to control my 4L60E with a carbed LS1.. So far I've learned that I would need a tps sensor to tell the tranny the rpm and that's it. Does anyone know any key points on how I can make my auto tranny work without the efi computer? This set up is going into my 76 pontiac formula. All info is greatly appreciated thanks
On another note, what is a good cam for a stock 346 ci 853 heads? With a carburator?

tci tranny controller

I've read up on the tci tranny controller as well but is there any cheaper controller out there? I'm doing a budget build

I got my FAST EZ TCU for 575, that is the cheapest I have seen and I had to use a 87-91 TPS and it hooked right in. Drive it every day, carbed 4.8 in
my 94 gmc.

the early 4L80E's in the trucks had a separate controller for the trans. like in the early 90's. dont know if this helps but worth looking into. especially if you have considered upgrading anyway.

Thanks everyone!!

why not run a 700?

A 700 is the weakest of them, and the electronic 4L60 has control that the 700 never will. No "kick down" cable, ect. Not to mention the 99+ 4L60 is a direct bolt on and the converters fit like they are supposed to.

4l80 is the way to go for real power, a 4l60 is on. Orrowed time when you abuse a car like I do.

4l80 is the way to go for real power, a 4l60 is on. Orrowed time when you abuse a car like I do.I would a agree for a stock 4l60e. But a built one will last a long time behind most street/strip setups. The performabuilt one i had in my 3750 lb 99 WS6 lasted for 2 years of abuse and is still going strong for it's current owner. Car runs mid 11s on motor and low 10s on spray so.

i would go with a 80E all day long.

1. they are just a much beefier internal design IMO, based off the old TH400's.

2. you could find a standalone module for them from the old ~94 6.5 diesel trucks in a junkyard for a hell of alot cheaper than any aftermarket.

3. the price of buying and building a 60E vs a 80E cant be enough to offset the added strength.

3. the price of buying and building a 60E vs a 80E cant be enough to offset the added strength.The added weight and hp loss (not to mention it is a tight fit in alot of cars) doesn't always offset...esp for cars in the 380-420 rwhp range. Bottom line is 4l60e trannies built right can handle alot of power, just not as much as a 80e. But in the poster's case, in which strength wasn't even the question or reason for the thread, a 60e will be fine.

Seen many a 4l60 that were built and eat the dust in time so a 4l80 would have been a better choice at 400 rwhp, they are hit and miss, a 80 is just damn bullet poof.

Thanks again, but I'm sticking with the 4l60e just because I already have it and on a side note my firebird will be a street car close to 400 hp.. I just wana get the damn thing running! Lol I am definately going with the FAST tci.. seems great and fully programmable

I had used the rossler trans controller on my 99 ss. It converted my 4l60 to a full manual valvebody. I think I spent $300.

Lol I am definately going with the FAST tci.. seems great and fully programmableIm useing the Fast EZ TCU,no computer(software needed)only the hand held programmer it comes with,I went with a Holley Carb. and used the Holley TPS,iT works great,Only trouble i see with it is if you nail it and decide it wasnt a good idea,It sorta gets confused and momentarly stays in low gear,Thats the only problem i have found with it,Price is way down compared to what it used to be.I think SummitRacing has it for alittle over $600

Yep, same issue here, it doesn't bother me but I was wondering if it was just mine.

The EZ Tcu is a GREAT piece. I sell a good amount of them. And I usually can beat the hell out of Summits price on them!

You can still get them from Rockauto.com for $90 with $50 core charge. This is the first time I have ever heard of using one for this.

I saw a TCI 302820 EZ-TCU for $564 on a google search.
