will a automatic transmission out of a 98 dodge 12 valve work in a 94 12 valve

 

As far as I know the 94 models came with a 47rh and the 98's 47re. The rh doesn't need a computer to run but the re does. You would need to swap in the computer and add a tps to make it work right. I would use a 47rh with a lock up converter and call it good.

what does a lock up torque converter do?

 

When a lock up converter is "locked" your engine and transmission are directly connected with no slippage. Less slippage means that less heat is building up in the trans and that can make it last longer. Another advantage is that it gives you better performance and increased mileage.

Not endorsing ats, that's just a pretty good explanation of how a tq converter works.

 

thank you that helped alot another question is if my fuel pump is turned up does that mean the star wheels is turned or not

 

You can back the star wheel out until it's loose and go from there.
