Obviously, by there responses, everybody needs to quit holding their breath waiting for this gizmo. I held out as well because I wanted to keep my stock gauges in my 66 GTO, I pulled the tailshaft off my T56 sent it out to get converted to a cable drive and within 2 weeks turnaround time and $360.00 which included round trip shipping, I have a perfectly accurate speedometer or at least according to my iPhone gps.
I first tried the Abbott CableX but it sent my speedometer needle to around 550 M.P.H. And broke the needle, I should have spent a few extra dollars in the first place instead of trying the CableX box and then waiting for this gizmo.

Who did your tailshaft conversion? Hey lizeec,
Who did the conversion for your tailshaft? Does this conversion still have the electronic output? I would still need the electric speedometer output to allow my cruise control, trans shift points, and a few other things to work with my set up. I may be willing to spend the bucks for the tailshaft mods if they still have the electronic output along with the cable output. And one last question, did you have to swap the little plastic gears at the cable connection of the tailshaft to get the speedo to read correctly, or how do you adjust for tire size/differential gear swaps, etc.? Thanks for your input. Regards, LAkers

He did a great job, I supplied him with my rear gear ratio and tire size and height and he calculates which drive gear needs to go on your tailshaft and which driven gear goes in the tail housing, he supplies all the gears and speedometer gear housing. All you need is new oil, some silicone to reseal the tail housing and I installed a new rear seal to be on the safe side, I just purchased a new oem style speedometer cable at the local parts store.
Yes I still have my VSS as well as it powers my cruise control, which works perfectly. My speedo was off and reading low by about 3mph according to my iPhone GPS, I talked to Dan and he said to change the driven gear to one with either one more or one less tooth I can't remember but apparently each tooth will change it by 3mph, I can't remember if I had a blue or brown gear but I switched it and it read perfectly with my iPhone GPS, the gear was like 3-4 dollars at the GM dealer and took about 3 minutes to install.
Sounds like you are looking for a tail housing for a automatic as you asked about VSS & shift points, if so I know street and performance and a few other companies do the 4L60 transmission tail housings, I don't know if Dan does the auto tail housings, it can't hurt to ask him. If you have any other questions just ask,
Good Luck Bob

i have been playing with a similar idea. Initially tried to drive with stepper motor but fast steppers are not cheap. Using simple 12 dc motor works. Two ways to control the motor, either use pwm control taking signal directly from the computer or integrate the signal from the computer for variable voltage. Still not fully finished but getting closer. I have looked into getting a motor with a speed sensor for precision, but so far looks like it will be close enough without it. This is something that i just had laying around, otherwise i would start off with a sensor equipped motor

If anyone else needs something right now or you're going to melt, DO NOT WAIT for me to finish. If you're on a deadline, get something else. Go to Dakota or AutoMeter or the scrapyard. I can not promise when or if this thing will pass beta QA and/or become available. I wish I could (since actually none of you could possibly be as impatient as I am to release this thing), but I can't.

We may never hear any more on this, but I wouldn't give up on these guys yet if I were waiting. I know I've got projects that have gone much longer than 7 months without anything. Sometimes life gets in the way....and sometimes you just have to step away from 1 project for awhile and work on another then come back.

ok, while im waiting on these guys to make the perfect solution for my elky, what other options are there other than cable-x to run the mechanical speedo with the VSS from my 4l60e?
i need to retain the mechanicalo speedo for the style im going with.
id like to research all my options, but my google-fu just isnt all that great...

Another option which is why I asked if you were going to aftermarket gauges - you could use an aftermarket set with a cable or you could use an electric set with a GPS interface. All available through Autometer.
