long story short I replaced my ISb if i could get in to 1st 2nd 3rd and 4th does that mean i should be able to get into 5th and reverse, because i cant get into those gears right now and there is a small crack on my tranny so i have to jb weld it before i put any fluid in, please dont hammer me on this question i was just wondering

 

What do you mean by "ISb"? Good luck with the JB Weld, it will not stick to oily metal.

 

An ISB is an input shaft bearing.

I'm guessing it might have something to do with the shift interlock.
