Well, this weekend I replaced the KDW on my 93 CDE. Not a bad job, really. And it cured my snapped KDW problem, lol. Anyway, it was pretty easy, pull the battery, and battery tray out. I chose to zip-tie any hoses/vac lines that were in the way off to the side so that I wouldn't have to disconnect any. Then, you make sure the valve body cover on the tranny is clean (especially around the edges, when it comes off you don't want dirt falling into the transmission) and remove the 4 bolts holding the cover to the top of the transmission. Pull the dipstick out and remove the cover. The next part is that you need to take out the metal pipe in the front of the valvebody (on turbo cars, non-turbos don't have this pipe), and you need to be gentle, as it will bend fairly easily, I sort of worked it out with a screwdriver on one end, and then swiveled it around and it pulled out of the tranny pretty easy. Here's the tricky part, you don't take out all the bolts from the valvebody!! Its pretty hard to say which ones they are without showing a diagram, if anyone wants this, I can scan it in and email it to you, or get the Automatic Transmission Service Manual on eeuroparts - its a HUGE help. After you take the, I believe 10 bolts out, just lift out the valve body, and set it on something clean and level, and watch the fluid running out, ATF isn't very good for paint. Now, the easiest part is changing the cable from here. You can see the plastic cam in there with the cable attached to it. Disconnect the cable from the KDW motor, OR the TB if its a non-TCS car. pull some slack into the tranny, and disconnect the cable from the cam, then pull the cable housing out of the transmission, use a screwdriver to coax it out as there are 4 tabs that you need to press together to get it out. After here its pretty self explanitory, however, do NOT hook up the KDW until you have the transmission fully assembled, and make sure the wire is as far into the tranny as it will go. If the cable is pulled all the way out when you put the valvebody back on, it will break the plastic cam (at least mine did, luckily I had a dead auto tranny in the garage I stole the cam off of). Other than that, reassembly is pretty much the reverse of removal. One note, it says in the manual that if that pipe that you have to take out on turbo cars is bent and cannot be straightened, to just scrap the pipe as the metal can come off the pipe and will probably damage the transmission. Also make sure the rubber O-rings are on both ends of the pipe, it says if they're missing that leakage will destroy the valvebody. If you need to do this and you have any questions, just email me!
-This whole procedure took me about 2 hours to complete, just for a time reference.
