This is "top of the head" (i.e. untested) engineering. My idea is to disconnect harness connector F42 and fashion a substitute electrical connector. Run the new harness into the passenger compartment. Mount a 5-position radio pushbutton switch to your homemade harness. The five buttons would control automatic gears 1, 2, 3, 4, and R.
Viewing the open end of connector F42 with the latch at the "12 o'clock" position you see two rows of four terminals. They are numbered 1-4 (left-to-right, top row) and 5-8 (left-to-right, bottom row). Terminal assignments are:
1 = Shift solenoid B
2 = Shift solenoid A
3 = Overrun clutch solenoid valve
4 = Line pressure solenoid valve
5 = Torque converter clutch solenoid valve
6 = ?
7 = ?
8 = ?
The question marks may be filled in by inspection of the connector and tests with an ohmmeter. One of them is for Reverse. The remaining one or two may be grounds.
The activation schedule for the solenoids is:
1st gear = A and B
2nd gear = B
3rd gear = (none)
4th gear = A
The Line valve solenoid would be energized if shift solenoid A, B, or both were energized, and de-powered during shifts.
I hope "Don in Texas" or other Maxima.Org members who know automatics will comment on this idea. Maybe it's whacko. Maybe it's do-able. Maybe it's not worth the trouble.

Someone here has too much knowledge.

I'm gonna go for it, I'll post pictures when I'm finished in June or July.

Here's a link to the post with a couple pics of the controller

Re: Here's a link to the post with a couple pics of the controller
- it's easy to operate
- the driver keeps both hands on the wheel
- the driver keeps his eyes on the road

A variation on the theme

- it's easy to operate
- the driver keeps both hands on the wheel

See that plastic pod on your wheel which contains the Cruise Control buttons? Buy one of those and fasten it to the opposite side of the wheel. On my wheel there is a removable panel as if somebody was planning for it. With some care, this could be made to look "factory".
I'd also like some kind of illuminated display which shows which gear the tranny is in.

That is some incredible sh*t. Does anybody have anything like this currently for sale, or would be willing to submit another prototype? I am not the most electronically inclined person, so is anyone interested in attempting this mod and willing to post specific step-by-step directions (detailed)? I appreciate any feedback and help. Thanks in advance.

TIPTRONIC OR SHIFTRONIC
THE ONLY ONE THAT OFFERS ANYTHING LIKE THAT IS LEVEL TEN. THEY HAVE A SYSTEM THEY CALL SHIFTRONIC. IT ALLOWS YOU TO DRIVE THE CAR LIKE IT IS A STICK. IT RUNS $1600. THEY SENT ME THE INFO AWHILE BACK. DESIGNED FOR THOSE WITH AN AUTO THAT WANT A STICK. CHECK THEM OUT OR EMAIL ME, I MAY STILL HAVE THE INFO. FURBISS112@AOL.COM
