Do you sell a driveshaft for a 4L80e with a 1350 u joint for a f body.

 

WTF would you sell a non-billet shaft etc for a TH400 conversion? Obvioulsy if someone is converting its because the stock **** cant handle it.

What power levels can your TH400 handle, over then 650rwhp?

Can you get the optional 3.0/1.57/1.0 gear set?
Thanks.

dam i called about a th400 with ls1 pilot and got told twice it would be 900+...thats why i didnt buy one.

 

The drive shafts are the same price for th400 and 4l80-e
You might ck with a local drive line shop as shipping will add to price

 

depends on what you want! the converter base is or $795.00 and you can go for a nitrous model upgrade thats $895.00 with shipping that sounds right
we E-mailed you as you are only 14 miles from my house in Alma Ar. and told you I can let you pick it up with no shipping!

 

I agree that the 4L80E would be a big plus. Unlike most of the guys here I drive a Vette. Most of the guys I know who replace their automatic trans do so because engine mods and power rendered the original useless, no shocking news there. So here is what I would pay serious bucks for.

#1) A trans that can stand up to the power.

#2) More gears. Why on earth can't someone make an automatic for our cars with 5 gears so that we can get a decent ratio spread through the first 4 gears. Then I want more overdrive so I can run a lower gear such as a 4.10 and still use the car on the freeway.

#3) Its got to work with the PCM. How you do that is of no concern to me just make sure it's PCM friendly even if it functions, in part, mechanically.

The tested packages sound like a good idea at first but I would remind you that converter selection is a very personal issue. I think you will find it hard to meet the desires of the larger customer base with packages. I like choices better than packages. But, absolutely, do test the units before delivery, that's a must.

 

What do you think about a PCM controlled th400 that will work with your stock PCM so that you can set you shift points and tune as 4l60-e, for those that do not want a full man valve body!
anybody on this!

Here ya go bro!

Would you like that auto in a 5 or 6 gear configuration?


5 ----> http://www.autointell-news.com/News-...r-11-02-p7.htm


6 ---->http://www.carcraft.com/techarticles...GM/index4.html


Let me know how it works out.
I'd like the 6 speed.

 

If I were running just a pure race car it would be great, but like most, I have a street/strip car so I need an overdrive. I already run 3.73 gears but if the OD was .6 or .5 to 1 I would be running 4.10's. The 4L80-e already has the electronic controls and an overdrive gear. Seems like the trans of choice for the F-Body but I do not know what it would take to get it into a C5. I can only assume it is a different case than the one the 4L60-e and the 4L65-e use.

If I could get a 5 speed trans I would even be willing to have my torque tube shortened and buy a carbon fibre drive shaft to fit the new deminsions. At first glance this seems expensive. But I look at it this way, if I make 400 plus at the rear wheels and race, it's just a matter of time before I am going to have to pay the cost of a performance built trans. While doing this the car is already apart, so why not shorten the torque tube if it would get me a 5 speed trans?

For the F-Body it's even better because all they have to do is buy a new driveshaft or shorten the one they have. A 5 speed automatic would be something no one else offers. NOW... that's a package!

At the moment I need some advice on my third purchase of a converter from Yank. See my e-mail to Dave from "thecartwrights.com" Sent it Tuesday.

 

Hmmm,
I knew about the 5 speed in the CTS, it can't handle our cars even in stock trim, but this is the first time I have heard anything about the 5L50-e. It says they plan to use it behind a 4.6L Caddy power plant.

Now, lets see... Dave Hill, who heads up engineering for the Corvette, used to be with Caddy.

OH DAVE, ARE YOU LISTENING!!!! WE WANT A 5 SPEED FOR OUR LSx CARS!!!!!

 

Ditto #3


Yank, I think if you updated your website with all of the parts you have to offer sales would go up ALOT. There is a huge market for all of the parts you offer but only 1/4 of the people know about it....

 

we have used the 5l50-e in fact I have one for sale in the conversion section
it is as strong as a 4l60-e but the smaller gear spacing helps clutch life
with the HUGE amount of TM GM uses
it also has a very small input shaft that is 27 spline not the 30 of the 4l60-e so they use a extra low stall converter with a very low STR to make it live!

 

I'm with the 4l80e conversion.

 

Do you have prices for individual 4L80E conversion parts, prices for complete kits? Is it possible to operate with the stock PCM, i've heard yes and no stories, but no for sure answers.

 

This is what I was gonna ask, I have a local tranny guy I trust and have for years. Would be nice to get a k-member, could buy a converter of my choosing along with a flexplate (if it needs a different one). So I'm mostly concerned about the crossmember cause otherwise I'd have to build one.

 

We have the crossmember www.converter.cc/drivetrain.htm and you will need our special 4l80-e to LS-1 converter any stall $895.00,driveshaft, transmission and you can get a crossover harness and custom tuning, or a special aftermarket controller, this is what I would do!

 

Get the package together and a price list.

 

lets say I have a TH400 and I just want the stuff that I need to install it,,??


and for christ sake update your site man!! I did not even know you offerd this stuff!

 

How much power can the 4L80E handle when built?

Can it be had with a T-Brake?

And the crossover harness allows HPTuners to tweak the shift points and control the trans like it was basically a stock trans?

Yes, definately price list please.
