Well I need to bypass my ECM/TCM control of my AW4 so it doesn't downshift when I force it into open loop due to the turbo. (don't ask, its a long story and has to do with the air/fuel ratio in closed loop.)

I made this simple mechanical shifter that actuates 2 normally open/closed switches. I made this with some crap I had laying around and some hardware store items.

This is a rough idea of what it will look like but this exactly how it works.

Its about 4.25"x3"x2" ish.




Its bascially just a rod welded to a big fender washer that I drilled recesses into. I used a spring and a ball bearing to give it a positive shift feel. Its pretty smooth and does have a good solid stopping point between gears.



I cut the rod and ground it down to center it. (no I didn't measure it) Then I TIG'd it on. The spacers are some 1/2 copper tubing I found in my basement.


I used the same rod and cut pieces off and welded them to the fender washer to hit the switches in correct order to shift the tranny.



Here is the schematic that you need to use to get the order correct and wired up. I printed the TCM pinout from the Shopkey at the shop.



Here is a quick vid of how it works. It will obviously be bolted down when in use but you get the idea.



I need to make a nice cover for it and get rid of the bolt that is the pivot and get a 1/2 rod and some locking collars so there won't be bolts hanging out of the side. I am also going to incorporate a lighted switch on the cover to actuate the convert lock up.

you know what i use is a manual shift setup that tricks the TCM into staying in whatever gear selected. its a really trick set-up that you can see in my dash picks. ( i put it right where the cigar lighter would be) I also have it so one LED lights up in first , two in second ect... ii can bypass the tourqe coverter to so you can keep it 100% locked for steep decents and stuff. you can see it at AWSHIFTING.com check it out!!:thumbsup:

Yeah, I really wanted an actual shifter instead of buttons.

think momentary buttons would work a little easier?

Cool, but can you put red LEDs in for the eyes and have them flash for 5 seconds after you change a gear? lol Reminds me of the shifter in the Bruce Willis movie, Armageddon.

Nope. You don't need to figure on what position what switch is in. Just forward to up shift, back to down shift.

Ok, got the cover assembly all set. I went to Cable and Connectors looking for a 3pdt switch which they had so I can run the tranny on the shifter or the tranny computer. While I was there getting more switches and wire then I'll ever need I see some hobby boxes. Son of a bitch they had one that was perfect!! I was stressing about having to make a box that would work and look reasonable. I think this does the job and was only $9.

I first started out by getting some locking collars to get rid of the big bulky bolt. There is no exterior overhang now from the framing.


I drilled and tap 4 holes in the side to secure the cover to the shifter frame.


The entire side comes off with a few screws to allow access to everything.


I made sure to get the box wide enough to put a lighted toggle in for the torque converter lock up.



All I need to do it mount it and wire it up. I will fit perfectly directly in front of my cup holder and I can leave my arm on the center arm rest and shift at the same time. Very comfortable. I may add my Hella light switch to this box too. There is enough room.

The rocker controls the converter lock up solenoid.

yes, I was thinking momentary's for my plan as I want to set it up as an H-pattern shifter.


that thing looks great btw.

Happ makes a nice h pattern shifter. I was going to use that but then I would need a board to control it. Here it is.

HELL YEAH!! I got the shifter all wired up and mounted. This thing works awesome!! My favorite mod to date!

Here it is mounted. Sorry for the blurry pics. Im not sure whats up with the camera. (thats my wife's department.)


Notice I changed the knob. Im a "ricer" at heart and found a Type ARrrrgh shift knob in the basement from my Honda days. I drilled it out to accept the shifter.



This simple switch contain 9 connections and switches the shifting from the shifter to the TCM computer. Its a 3 pole double throw switch. $20 meh.


This is the position of my arm in the normal position when I drive. The shifter is nice and comfy to use!


Im very happy with the way this came out. Works great! Converter can be locked up with the lighted switch and also works great.
