Commercial-type sales postings will not be allowed.

VIEWING MULTIPLE TOPICS ON SCREEN: You can choose to see more than 10 Topics at a time ... Log In and choose "Preferences" from the top bar on the Forum page. Scroll down and Change the "Default Topics Returned" parameter to 25 or 50, and save the changes. Since this setting is stored in your browser 'cookies' (if enabled), it seems to use that stored value even if you are not logged in. So, if you use a PC that you haven't logged into the forum from, the setting still seem to remain at the default.
EXTERNAL PHOTO LINKS ON FORUM: You can still use external photo links in your posts on the new forum. They follow the rules of any link in that they have to have the URL link qualified down to the full image file name (example: .jpg). The links will open in a new browser window, the same as an uploaded image attached to a post. Since an image attachment to any post does not display inline with the post, the results are the same. You can use multiple external links within a post. This link is from photos on a site from Don Clink's 'Deuce@75' albums:

Using links from photo sites such as Photobucket can help in "size" issue with uploaded attachment files. For best viewing in web browsers, photos should be around the 800x600 pixel range, and probably not more than 1024x768. Most cameras today store HUGE jpg image files, as the default settings are in the 7, 8, 10, and 12Mb image sizes. The image files that are then attached are very large, and the browser can't display the full image size without using the scroll bars. Use the re-sizing functions of your photo editing software to reduce the image to 800x600, which reduces the file sixe and the image load time in the browser. Don uses Google's free Picassa3 software, which is an excellent photo management product. All of the photo albums of the Deuce, Grand National, and Auburn that are links on the NORG site were built using Picassa's web creation functions. And it's free? (THANKS to Don Clink for the info!)

Look closely at the picture and you will see two holes at the bottom of the plate. These should be nuts and bolts and will let you remove the solenoid. Then there is a hole at the top which is the remaining one holding the cover. When the cover is removed the other bolt holding the plate is accessed. The plate is then rotated and removed. You should not have to do this unless you want to replace the seal. It is the same one for all but there is an extra one for the adapter.
If you remove the solenoid and disassemble it take note of the angle of the flat in respect to the rest of the solenoid. There is a weep hole on the cover that should be positioned on the bottom to let out moisture. Also there are two coils on the solenoid. One is a pull in and the other is a holding. When it engages there are a set of points in there that switch one from the other. Also there are a set of point to ground the coil when the kick down is engaged. It may sound confusing but it is all pretty simple.

Its got the convertible plate to off-set it. The one bolt look hard to get at, but I suppose its do-able.

I am going through the complete test of the system as soon as the temps lower some. The govenor look like it wouldn't be real easy to miss with either. Some
say the points may need cleaning up. If it has to come
off to do that, how bad will that be???

Also is there an oil seal for the plunger like the sedan for the solenoid

As the photo shows, the convertibles used a special right angle adapter for the solenoid. Without it, removing the solenoid is not possible without pulling the transmission.

If it looks like that you just take out the two bolts and the solenoid will turn and come out. It should be under the transmission so the frame is not in the way. You do not need to take out the governor to test it. Just hook up a temporary test light from the power out side of the relay. If it comes on when you go over 23 mph then the governor is working. Next step is kickdown switch and solenoid.

Mine looks like the picture, but the frame is close to unit. Not much room for wrenches. I'll check the goveneor before removing the solenoid. But, like I said sometimes it work OK. So when I am testing things
it is operatoring normal. When its hot and doesn't work its too hot to do it under the car.............
Jim Taylor Thanks for any help. PS I'll let you know if aand when I get it fixed.

It should not be buried in the X frame. Someone has probably removed a bit of the X member and put a non-convertible installation. Here is an overdrive showing the assembly that lets you mount the solenoid underneath the transmission.

As I recall, the dash cable position doesn't matter. Removing the solenoid in a convertible can be tricky, but turning a quarter should disengage the shaft. Check both the pull and hold points in the unit when you get it out. They should be dressed to remove any burned spots. Before you do that, check the governor contacts to be sure they are not sticking. That sound more like the cause of your problem.

My OD will not re-engage after driving 20-30 miles after slowing down before 22 mph. After the car cool off it works fine until its been drove on the highway.

When taking the solenoid off a convertible, where should the pull cable be, In or Out? Do you turn the unit a quarter of turn like the sedans? Never had one out and its buried in the X fram. Thanks for any help
