At that price I can go thru say 8 4l60 rebuilds and have a spare tranny to boot.

The 4l80-e is a much stronger transmission than a 6l80-e, and you have No upgraded or aftermarket parts for the 6l80-e.
In the 6l80 conversion you will have to add a new Differential as yours will not fit, also a new torque tube and a costly programing package
but you do not have any torque converters that you can buy other than stock 1500 RPM stall, as no aftermarket units are out and a raised stall will not work with current Transmission control system.
Do not forget about the Core fees that GM charges you for.
The 4l80-e c-5 kit comes as a complete setup inc. a custom built two piece torque tube with a super Heavy duty U-joint driveshaft, it has a unique anti-torque transfer design for rotation that stops driveline twisting.
A unique custom multi plate lockup converter that will only fit this kit, and the transmission is a real special unit as it has a shorter case and all CNC machined adapters and shafting.
It also fits in the same space as the TH400 kit we sell
It is a great setup to handle big power and is about the same cost range as a 6l80-e swap that will use all stock GM parts

A TH400 base kit for c-5 is $7900.00
you can add options to make the cost go up
The 4l80-e is intro. priced at a low $10,500.00
but this is for 30 day's
and the 4l80-e has many more standard features,and is a difficult conversion on our part, as to all the special made costly items it uses.
Please PM me for any more info or contact East coast supercharging on this forum
Thank's

. You are essentially $3K for the overdrive over your TH400. I think the avid racers will just stick with the TH400. The guys that will want to do a 4l80 conversion are probably looking to really hammer the car at the strip and be able to drive the car on a more frequent basis. There will be a couple of people willing to pony up, but time will tell how many. My guess is, once you pass the 700-800rwhp level, you are willing to make a few concessions. If its cost on your part that makes it difficult to produce this part more cost effectively, than you may need to find a solution or selling in higher quantities might help bring the cost down some. If you do the math, your conversion is more 5 times the cost of a completely rebuilt 4l60E or for that money, you could buy 2 4l60E's (1 as a spare), have RPM or another vendor rebuild them 6 or 7 times (3 or 4 full race seasons)and still not spend the same money.Re: the 6sp auto..well while everything you mention is true for now, time and opportunity (for Vendors) has a way addressing some of the things you bring up. At $11K for your parts, I can afford to wait
Rodney put me on the annual rebuild program.
I mean you no disresect, and I do have one of your convertors on my Z and I have to say that I like it. I will hopefully be getting it to the track this week to see how well it performs.signed,
Fairly hardcore, but not hardcore enough$.

I also agree. It's $10,500-$12,000 just for parts, this doesn't include any labor cost which is going to certainly add the $$$. Keep in mind the floor has to be cut up and reshaped to get this thing to fit, I'm not to sure how many are going to want to do that as well.
Anyway, you're looking at $15k to do this mod!
Also, this still doesn't address the weak differential. For what this costs, you might as well back half the car and put a straight axle in for less...
