Welcome to TRS
A4LD and the 4R or 5R are the same transmissions, the A4LD just has a different valve body, FYI
If you have a 4.0l 4x4 then you can only use an M5OD-R1(M5R1) from/for a 4.0l 4x4, 2WD won't work
M5R1 from a 3.0l or 4 cyl also won't work
But yes, any M5R1 from a 1990-2011 4.0l Ranger or B-series 4x4 can be used(1994 and up B-series)
And will bolt up to your current BW1354 transfer case, need that because it has the 4x4 speedometer cable hook up, after 1997 they do not have that
The 2001 - 2011 M5R1s have a different shifter arm, so get the M5R1 complete with shifter
I think you can use the clutch/brake pedal assembly from 1993 to 1997 Ranger in a 1994
And you will need a 1990-1996 4.0l Flywheel, 6 bolts, 1997 and up 4.0ls were changed to 8 bolts
The M5R1s use ATF, yes automatic transmission fluid in a manual transmission, Mercon V was spec
Your 1994 4.0l computer will have automatic transmission software, so it will "look for" the transmission solenoids with Key on, and won't find them, lol
It will then turn on the CEL(check engine light) and set codes for solenoid faults
Everything will work fine, so driveable
Idle will be high because automatics have higher idles
You can swap in a 1994 4.0l manual trans computer, plug and play, if you can find one, 2WD or 4x4 don't matter to the engine computer
If you are in an area that has emissions test then you will need a computer that has that requirement, "earth" was not specific enough
