fully manual, electrically shifted 4L60E ?

I just found this very good article about converting a 4L60E to fully manual, I would like to know if it was possible to shift gears with 2 electric switches connected to my steering wheel, one for upshifting and other for downshifting, kinda F1 like. since in this article the solenoids were removed I think that's not the way to go, but what if a wiring is setup for activating the solenoids at will? does this tranny works that way, is it's shifting controlled fully electrically or what?
Augusto.

I don't know about removing the solenoids -- most transmissions use them for shifting. If the solenoids were removed the valve body had to have been replaced also.

You can use the switches on the steering wheel, but need to create an electronic up/down switch, and the wiring would wrap around the column.

I have a Jeep AW-4 electronic auto trans in my 63 Rambler. It's all manual shift. I still have the column shifter for reverse, park, and drive, but the trans will not shift unless I turn a switch. I just traced the wiring harness out to find the three solenoids (one for the lock-up torque converter, the other two for shifting). Then run a power wire from the battery to a switch, and turn the correct combo of the two solenoids on for four gears. Both on is first, both off is fourth (OD), I forget the combo for 2 and 3, but one is off, the other on. I wired a four position rotary switch to "dial" the gears, required a couple diodes to prevent back feeding the solenoids in some positions. The switch is mounted on my center console where my hand rests right over it when on the arm rest. It's nice an convenient! The car is in my album, but I don't have any interior shots. I like it! I started out with toggle switches just to test the transmission because I was having problems with the shift computer. Since I have the rotary switch I'm not going to bother with a computer.

Farna, like your rotary switch idea, never thought of that. How does your transmission control line pressure? I know the Fords need an external PWM signal from a computer to maintain proper line pressure, maybe yours is internally regulated somehow?

I used the Baumann transmission controller (they only do Fords though) and they have the option of using your cruise control buttons for upshifting and downshifting. The theory is the same though, it is just energizing and de-energizing solinoids to controls the shift points.

Augusto, do you have a link to the article? (assuming it's online)

take a look, and if somebody comes up with a paddle shifter for this monster please let me know.

Thanks for the link. interesting read. That looks to be a permanent upgrade though and tailored for the the track. They are not limiting the line pressure at all and I'm not sure that's a good thing, at least for the street.

The more I think about this, that is what a lot of the new performance cars are doing with the "autostick" in the manual mode, moving the shifter simply sends a signal to the appropiate shift soilenoid. Looks like Farna is way ahead on that one.

there is a paddle shifter kit for the 4L60E trans... I need to find the information I have.

Got the info from the PRI show participant..

Arrowhead, the AW-4 uses a throttle valve cable like the 700R4. I think the 4L80E also uses a TV cable? I didn't know the Ford AOD (or later models?) used an electronic pressure control. Toyota used an electronic gizmo in place of the TV cable on AW-4 models in the Supra, but use the TV cable on trucks that use the same trans. Toyota has a different model number for the AW-4, but it's the same trans with some minor mods.

The
AOD does use a TV cable, the AODE and 4R70W have electronic pressure control. I belive the AODE and 4r70W are the same except the4R70W has a wide gear ratio set. All three have similar cases, but different internals depending on year.

PLEASE !!!! look for the info and let me know, I have a 4L60E sitting homeless, it could be the perfect mate for the 454 that sits behind it.
Thanks.

Remember it still needs an aftermarket shift computer:

"Twist Machine’s proprietary electronics are “plug & play” compatible with leading aftermarket transmission controllers from TCI, Compushift, Powertrain Control Solutions and Baumann Engineering

I dont understand why they didn't do this electrically, using an arrangement of switches and diodes. With a little electronics skill, you could make a circuit that would provide a PWM signal to the line pressure solenoid using the TPS on the engine.

Anybody knows anything new to add to this post? I still want to use that 4L60E but don't want to spend $1.200 on a computer, full manual will be ok, electrically shifted better.

Augusto.
