I think you are correct. I spent a long time on my back under the Jeep trying to put the transmission brake back together. But after a lot of frustration I gave up and put the problem to MLU members.
Their answers got me thinking and I solved my problem from a frustration into an easy job to fix. I can't understand why the original guys building the Jeep did not add another small inspection point take make the replacement of the hooked bolt easier to work on.
I used a long screw driver and pushed it from the bottom up through the holes to the floor and marked the spot directly in line with the holes that would take the bolt.
I then drilled a pilot hole from underneath to mark the exact spot. I then drilled a large hole from the top to take my electric jigsaw and cut the hole.
The hooked bolt just dropped through into place, I pulled the bolt upwards and placed the spring on the bolt lowered it a bit, put on the second spring and dropped the bolt through the last hole and put on the nut. so easy.
I then cut out a small cover and screwed it over the hole and painted it.
The transmission brake regularly needs to be removed, cleaned and lining replaced so why not make it easy to work on. I hope this will help others out there in MLU land.
