NO. The 1998 has a electronic governor while the 1994 has a mechanical governor.
It may fit, but the control systems are different and it will not shift.
sounds like to me your transmission needs to be rebuilt
A 1995 should work.
The part number is 2118350
O2 sensor or vacuum leak
Not exactly. The motor is the same, but the transmission is different. The B vans with the 3.9 used a mechanical 3 speed automatic (32RH), the Dakota used a 4 speed electronic automatic (42RE). You could use the engine but not the transmission.
In 1994, Dodge used Emerald Green Pearl Metallic.
