i have the gbox out of my vit, and i cant select the bottom row gears. does anyone know why?
i hear sammys have a shifter bush that needs replacing every once in a while, could it be a shifter bush for the gbox too?
The "shifter sheet" problem on the Samurai/SJ-413 is found in the transfer case, which has a different shifting mechanism design than the Tracker/Vitara/Sidekick transmission.
Looking at the manual transmission section of the '96 GM FSM (pg 7B-10), it appears that the end of the shifter arm fits into a socket in a single linkage shaft. Moving the shifter causes this linkage shaft to rotate and slide length-wise to select the gear.
The Samurai transfer case has two rods with notches in them forming a "pocket" in which the shifter arm fits. A worn-out "shifter sheet" can cause the shifter to place one of the two rods in an "invalid" position relative to the other rod causing the transfer case to (usually) go into "neutral".
what about having no oil? does this make it hard/impossible for the gears to mesh and slide in?
I assume that you mean that you have drained the gear lube out of the transmission and are trying to shift it on the bench. I don't think that draining would adversely affect shifting on the bench -- unless -- you were having problems when it was in the vehicle.
Isn't this the truck that had damage to the clutch "fingers" that rest on the throwout mechanism?
I hate to be the bearer of bad news, but it looks like it is time to open the transmission up (or take it to a shop) and find out what is wrong.
There is good news! At least you don't have to worry about the expense of the shop removing it from the Vit!
