Transmission Goes Back Into Humpty Dumpty - Almost!

Transmission Goes Back Into Humpty Dumpty - Almost!
With the help of various people from Germany and America, the transmission started to go back into Humpty Dumpty:
1. Tiptronic® Transmission – Blueprinted, Polished, Reinforced And Dynamometer Tested Race Version
2. High Performance Software For Tiptronic® Transmission Including:
a. Specially Programmed For Use With 3.8 Liter Engine
b. Permits Driver To Hold Transmission In Gear In "Tip" Mode – Transmission Will Not Override Driver
c. Higher Performance In Automatic Mode
d. Transmission "Learning" More Rapid In Automatic Mode
3. Torque Sensing Differential Mounted To Ring Gear With Specifically Made Stainless Steel Bolts
4. Carbon Fiber/Titanium Side Transmission/Differential Housing
5. Wire Electro-Discharge Machined 300M Transmission Output Flanges
6. Lightweight Flywheel
7. Titanium Transmission Linkage Brackets
8. Aluminum High Efficiency, Lightweight Transmission Oil Cooler
9. Goodridge G-Line XF –8 Hoses With Machined Aluminum AN Fittings From Transmission To Transmission Oil Cooler
10. –8 Aluminum Quick Disconnects Between Transmission And Transmission Oil Cooler
11. Titanium Transmission Fluid Fill Plug
12. Carbon Fiber Transmission Fluid Pan Including:
a. Titanium Banjo Level Indicator Fitting
b. Titanium Drain Plug
c. Aluminum Fasteners
13. Titanium Transmission Fasteners Throughout
14. Titanium Transmission Mounting Fasteners
15. Titanium Differential Fluid Fill Plug
16. Magnetized Aluminum Differential Fluid Drain Plug
But as this was being done, the assembled group had three more "simple ideas" -- which, together, will save over a 500 grams of weight:
1. Replace the black steel mounting arms with titanium equivalents.
2. Modify the carrier so as to reduce weight.
3. Remake the mounting bracket to reduce its size and the size of the Delrin® mount.
So, a few more weeks! And, yes, after the car is complete, one might look at remaking the entire case in magnesium (given the liquid cooling channels and other design features of the Tiptronic,® an entire carbon fiber casing would not be practical) and/or redesigning certain components such as the torque converter!!

I'd be pretty nervous if I was one of those guys balancing that "fortune" on the jack!!!!
Thanks again for sharing these pictures - what a beautiful creation!

Any chance the reprograming would be possible in the future for us TIP drivers? Something I am sure a lot of us would be interested in buying

It is, of course, technically possible but I would not let anyone but an expert do it. And, as for each action there is a reaction, changing the programming can have a variety of effects on the wear characteristics of the entire drivetrain (e.g., the internals of Humpty Dumpty's unit are quite different from the standard -- for this reason and due to its increased torque), on safety, etc.

You might actually use Magnesium on this beauty? Didn't think you were a big fan of the material.
About time Magnesium gets some credit for being of value when it comes to weight savings.

you bore/drill a hole in the plug and glue the cylindrical magnet in it. (in answer to previous question) I noticed this in the drain plugs in my car and I was ecstatic. Used to do this to all my old cars, though I never kept them long enough for it to matter.
I have a question. Why stainless steel bolts instead of high grade titanium. Similar alloys for expansion reasons perhaps? High strength Ti alloys are comparable to HS SS's and are more corrosion resistant at normal temperatures. I don't recall the fatigue data, but I think the good Ti alloys are superior to SS in that regard. Just curious since cost doesnt seem to be an issue with this project.
