1985 2.0 Manual to Auto Swap Options

[CodyP23]

1985 Ranger with 2.0 engine and TK5 manual transmission. What would my easiest option be if I wanted to swap to an automatic trans? I couldn't find any existing threads regarding this engine/transmission combo. Thank you!

I'm not familiar enough with the engine to say what is all needed but someone else will probably know and help once they see this.

Normally, one would need the wiring harness, the pedal assembly, parts for the steering column or the whole column, and the PCM from an automatic. I'm not sure if the year of truck you have needs all that since I believe the engine is carburated and the transmission might not have any computer control. So, it might just be the pedal assembly and parts for the steering column/steering column.

An '85 won't need anything done with the steering column; they were all floor shifters until '89.

I suspect that originally the A4LD, overdrive auto, was used for the 4 banger auto, as it was introduced in '85.

If it were me, I'd look at converting to the C3 three speed auto that was used with the 2WDs up to '84. It'd be tough to find a working A4LD with a Lima bell pattern, and you'd need to swap to an auto computer and do some harness work. A C3 doesn't need a computer, but you don't get an overdrive gear.

I think that a C3 would make for a far easier swap, in converting manual to auto, and you might check to see if Pintos or Mustangs used the C3 behind the Lima 4, to broaden the donor horizon.

You'd need a flexplate, the floor shifter, and you might can just swap the clutch/brake pedals for an auto brake pedal and reusing the original mounting bracket (which can be done on the second generation trucks). Not sure on the driveshaft, nor on the starter.

Good luck!

I don't think they even made 2.0L Rangers with an auto so that's probably why you aren't finding much... and being a computer controlled carburetor options are limited, the C3 option Robbie mentioned is likely the best...
