Today I had quick go at fitting a MOMO auto shift ****. I am not sure if you are meant to use any of the black rubber adaptors or not. However it sort of wouldn't engage the plunger to enable gear shifts. I was just holding it and it was a quick attempt. However I have suspected for a long time my auto plunger sits too low in the lever. It only just clears the top. I wonder if its the issue for the MOMO. If anyone can describe how the MOMO goes on in particularly the black rubber bits please let me know. And if my shifter is too low and what the fix may be. Note the standard shifter is fitted in the lower holes. Thanks.
I have had a Momo shifter on both my trannys, first on the 90S4 and then I deployed it on my current GTS after I lost the S4..
Fitment was about as simple as can be with no adapters needed as I recall. The **** simply slides over the shaft and is held is place by a grub screw low down on the Momo unit that has to be tightened to restrain the reaction. The central push button then pushes on the inner plunger to release the latch and thus permit travel of the main lever as required back and forth..
The Momo unit is far superior to the crappy original item that invariably falls apart after 12 or so years of use or did so in my case at least.
OK I will have another go at it. It just wouldn't push the plunger down. My push rod almost sits level with the top. The standard one still works as it comes in from the side and pushes through the slots. Can the push rod be adjusted.

Greg,
The plunger rod in the centre of the tube should not put up much resistance to engagement as the thing takes little in the way of effort to get it to engage.
Sounds as though there is something causing it to jam but what I have no clue. Can you get the central plunger to depress simply by pushing down on it?
The fitting instructions go something along the following: turn your car to on, pull your shifter into "N" then put the momo back on, and then push on the MOMO button then push down on the momo at the same time and make it fit, then screw it into place, then let go of the button and see if you can push it back into "P" and have it stay there without being too loose
Nah the push rod moves very easy. However not much sticks above the lever. The momo works by pushing downwards. If not much sticks up then it cant be depressed enough before it bottoms out on the lever top. If I lay a flat rule across the top of the lever its not enough to release the mechanism. If I push it a little further in with my finger it works. However the original handle pushes from the side and has a progressive bit that goes in between the slots. What I am interested in is from my picture should the push rod be sitting more proud or is it normal. I suspect a weak spring or something in there. I will try again tomorrow and follow your instructions. However the momo plunger is not narrow enough to go internal of the shaft to push the rod enough. I can probably extend the rod a little. Lets see how I go with a better attempt.
I agree the MOMO fitment seems very simple. I dont have any springs on mine. The rod looks different to both of yours. Also it does not sit anywhere near as high. It only juts out a few mm. If I push it down level to the top of the handle it wont shift and this is as far as the MOMO can push. It does spring back so I assume the mechanism is controlling that. I could easily extend the rod a little. However it would be good to know what the issue is. Maybe my rod has been modified or broke or something like that. I wonder exactly how long they are. Also looking at your lever you only have one set of holes for the grub screws. I have two for mounting the original lever lower. I wonder if thats factory. Mine wont work in the upper holes which may indicate an after thought due to a short rod.
Interesting differences in the push rod! I would be curious on what PET shows as far as part #'s.
Since you are not using the stock T-handle w/ the side button, you might be able to try different length dowels or aluminum or steel rod until something works. If metal, just make sure you smooth it so it won't wear on the Momo or anywhere else.
Yeah I just dropped a punch in there that was about the correct size. almost the perfect solution. Just a little heavy. I found I couldn't put a small piece of aluminum tube on the end as the recess is too narrow. I will get a short piece of rod from somewhere and make it more permanent.
The push rod seems too short. The punch clears the top by probably 10 more mm and works fine with the MOMO. Guess I will never know the issue unless I can get my hands on another push rod for my model. I will make up a new rod.
