Welcome to TRS
2WD or 4x4?
1985 to 1994 Rangers used the older EEC-IV 60-wire computer, for fuel injection and automatic transmission control
Your 1994 would have the A4LD automatic
And you would want to use an M5OD-R1(M5R1) manual transmission for this swap
The M5R1 has an integrated bellhousing so each M5R1 was made for a specific engine, not interchangeable
So an M5R1 from a 2.9l engine would not fit on a 2.3l or 4.0l engine
You would need to find an M5R1 from a 1989-1997 2.3l Ranger, 2WD if thats what you have, 4x4s are different
Can't use the 1998-2001 2.5l M5R1 because it wouldn't have speedometer cable hook up
2001-2011 2.3l was a different engine so wouldn't fit on your 1994 2.3l
Besides the transmission you need the flywheel and clutch, the clutch/brake pedals and clutch master, clutch neutral switch, and shifter floor plate with boot
Need the rear drive shaft for manual trans to match your length, regular cab or extended, or long bed
Need manual trans starter motor
Manual trans steering column is optional, but would be nice to get rid of the auto shifter
The automatic computer will turn on the CEL(check engine light) if the A4LD is not hooked up, but you can still drive it
Getting a 1994 manual trans 2.3l computer would be last step, its optional but needed, since CEL is on full time you wouldn't know if computer set another code not transmission related, unless you checked the codes every few days
Its not a simple swap and will take a bit to round up the parts unless you can find a 1993/94 2.3l 2WD manual trans Ranger to get all the parts from at once
