could a week shift cane cone shaped retainer spring cause it , the big one under the twist & lock dowel pin retainer cap i remove in the video with the SST ?
Yes, but I don’t see how it could get “weak”. There is just enough up and down play that it someone leans hard on the end of the shifter it can pop up and out of its slot.
First time I ever encountered this was in an FJ40 driven by a girl who used her shift lever like a grab bar as she drove over rough terrain. One hand on the wheel, on on the knob and popping it out of gear/jamming it between gears on an almost regular basis. We could not seem to get through to her that it was a bad habit and terrible driving style. But at least it kept the beer out of her hand while she was driving the trail.
It might have come out of its gate. Take the shift cane out and peek inside with a flashlight. Use a large screw driver or pry bar to pry the reverse shift gate slot in line with the other two shift gate slots and reinstall the cane. Post up a picture if you are not clear which one is out of line.
Gonna try your suggestions tomorrow morning to free up this H42 that's stuck in reverse gear .
@ksrunner & I would really like to know the why and how , surrounding it occurring in the first place ?
I plan to take few detailed photo's of the cane itself & engage tip .
I have a Theory that might hold water or Not ?
is it possible to install and use a J30 cane in a H42 , if u also installed the H42 Lever spring & twist lock dowel pins retainer / Lever cap ?
this 1978 FJ40 has a Mix of early 1970's parts on it as well .
there is No Good reason so far for the stick to have popped out of reverse like it did , so knowing & understanding the root cause would prevent a future failure and vehical breakdown stranded situation
I just noticed that yours is a 78. so this does not apply it is on for the 8/80 and later 4 speeds with the aluminum top plates. This is a common issue in the FJ60 when the seat goes bad. However yours being a 78 this is not the issue. Sorry

we dug further into the Mystery H42 getting stuck in Reverse gear position & discovered how the problem occurs , but the Why factor is a even
bigger mystery now . Please see attached Grey FSM Diagram & Red ink notations below
I used a big flat head screw driver and Lined up #9 Reverse shift head , #7 1st-2nd shift head , & #4 shift fork , so that all 3 were in the center
position ready to accept the cane tip , the first try i was on target and proceded to use the SST gear shift remover to re-install the spring loaded retainer
i pushed in the clutch and proceeded to run the shifter through the 5 gear positions , The engine was NOT running at this time
everything felt normal for the first few trys , i then put it in neutral , for a few minutes . went back and the shiftier was stuck again in the
same general area and truck locked in reverse again ? i was like WTF ?
so i pulled the cane again and starred hard down the hole at the 3 shift heads that i lined up initially , the reverse shift head was a inch or so
forward ( towards the engine ) of the other two ? i proceed to use the screwdriver to pull it back to center , as i did i felt pressure or
resistance , i got it back to the center alignment with the others spot , and pulled the pry bar out , i then noticed the #9 Reverse shift head
Move on its own / by it self forward again ? sliding slowly under its own power back to the same spot we found it the first time ?
i repeated this step a few times and same results ? So whats happening is when u shift from reverse to Neutral when the truck is engine
running , that #9 reverse shift head is sliding up forward to the reverse gear shift position without the cane tip engaged , it gets left in the
Neutral position and cant get out and go any where . the depress button on the #9 reverse shift head does seem to work normally
i can take a screwdriver and move the reverse shift head back and forth / front to back w/ button depressed at the same time , with NO
major resistance , again i was even more like WTF ? Then it hit me there should be detents or points of locking resistance , and there
appears to be none . So i asked myself what or why would the #9 shift head move on its own forward like is does , and i thought of the
reverse light switch is spring loaded contact maybe pushing on it ?
So , how come the Reverse shift head move freely back and forth like it does ? maybe #2 Detent Ball and Spring are broken or missing
some how
i mentioned above that ALL the #1 shift Lever Retainer bolts show signs of recent removal / re-install .
Based on the Symptoms & the current Moving parts behavior & function any additional thoughts on what can cause this or how its happening , Why ?
My theroy on the Broken or missing #2 Detent Ball & spring is just that , also is My thoughts that the reverse light switch spring loaded contact tip is pushing on the # 9 rod to make it go forward on its own like it does , ?
But , as of now that' all i Got ...............
Any Constructive Input or Comments are Appreciated
