LOL...I was going to mention that ,those are tender an require only very slight turn to make a change ,you
can also damage the spring by over tightening it ,also ,you have to make sure that the little screw dont
vibrate loose!
Some people also make the mistake by thinking it is the set screw to...
There is many things that can cause this issue ,including ,things that dont include really the transmission!
Like loose drive shaft hub pins or grub screws that tighten the shaft to the output shafts on the trans or
to the diffs!
Also ,make sure that the flywheel on the engine is not slipping...
There is hidden components inside the trans that you will not know that they are bad!
One is the Pawl ,they have a swinging arm that swings out an catches a pin in a hub ,if the
arm doesn't swing out ,then it is jammed!
Two ,there is a O-way bearing in which consist of tiny needle bearings...
If that truck has reverse ,it could be quite possible that the shifter is stuck in a neutral state ,or
in between reverse & forward ,what ever mechanism works that part ,make sure that it is working!..:cool:
