Question--Will the A4LD fit my 77 pinto 2.3 engine-if so would there be any modifications-ie:could I use flex plate and torque convertor from A4LD on my 77 2.3 engine??
tks

I'd like to know the same thing. I have a good 2.3 A4LD from a 1990 Mustang that I cant seem to sell. Might consider putting it in my 79 if its not too much work.
You can put the A4LD in behind the 2.3 but you have to change the felxplate and torque converter to the A4LD pieces. The A4LD uses a lock up torque converter. Also The A4LD is longer so you will have to shorten the driveshaft.
what fords and what years did the A4LD come in --also would I need any type of extra harness etc to make this work if I install one behind my 1977 2.3 engine
thanks in advance

I have an a4ld in my shed that I was thinking of putting in a Pinto also.
It is a few inches longer than a c3 and the mount is farther back. Thats what stopped me.
There are 2 solenoids that will need to be wired in- one allows/prevents the trans from going into overdrive. Should just need a manual switch to 12 volts. The other solenoid controls the lockup torque converter, and may be more complicated to connect up. I was going to experiment w/ it, but like I said, the tranny mount situation stopped the project before it began.

You could wire up the solenoids to toggle switches but what a PITA. Not so much of a problem flipping a switch to go into OD and then another for lockup, but if you forget to turn them off and you leave the converter locked the engine will stall at a stop. I have the entire set-up from an '85 2.8 Ranger. Most of the wires to the PCM can be eliminated, you need power and ground of course, also VSS, MAP and TPS. I have the PCM, harness, all of the sensors, carb (with the TPS), trans,converter,flywheel and shifter. I was going to put it in my cruiser but I have my eye on a turbo coupe at the moment, so this stuff may be up for sale!
Was going to do this in my CW clone, but have since decided I want a V8. I do have a question. Why wire up the O/D to a toggle? My Mustang has an A4LD, and the shifter actually has four fwd gear selections...Shifter layout is: P-R-N-O/D-D-2-1 Personally, I was going to use the Mustang floor shifter, and was going to either leave the lockup disabled (O/D without lockup is still more fuel efficient than C3 without O/D), or, hook it up to a toggle like you, with an indicator light somewhere eye-catching so I'd know when it was on/off. I even toyed briefly with the idea of, if it was toggled, for it to cut off below a certain speed (like 45 mph) so it wouldn't stay on at lower speeds. The problem I had, is I do not know what kind of signal the lockup requires for it to engage. Is it just a simple 12+vdc solid, or is it a momentary pulse like a spike to turn on and another spike to turn off. Maybe that would only be the internal inputs from/to the ECU, and maybe I am over complicating things, but I just didn't know enough about the lockup. And, now it's a moot point since I am going with a v8, possibly with AOD, and those things have (thanks to the Mustang following) stand-alone systems for them for non ECU-controlled vehicles. Maybe one of those setups could be used and retrofitted to the A4LD? Who knows?
btw, there is a bit of a write-up on the A4LD over on the ranger station: A4LD (http://www.therangerstation.com/tech_library/a4ld.html)
They even have a PDF copy of the A4LD Service Manual (http://www.therangerstation.com/tech_library/pdf_documents/A4LD_manual.pdf) (right click this link and save to your computer if you want a copy ;D)
Good info Doug, it looks like the earlier trannies had only 1 solenoid for the converter lock up. That would simplify things a great deal, just 1 toggle for converter lock up and you still have OD.
I have a C3 in my Pinto. When i put it in I forgot to count the number so splins in the input shaft as I had all the pieces. Now I need that information, can anybody help.
thanks

Never done this swap, but just a thought, if you want the lock up converter to cut out, why not hook it up to, or through a brake pedal switch ? Cut the power when the brakes are applied, would that work ?

I thought of this, but I think that as soon as you released the brake pedal, the converter would lock up and either kill the engine, or you would take off like a shot. I'm not sure though.

No help on the spline count of a C3????????? Somebody has to know.
Ok, slightly more awake, but i dont think it would be that hard to hook the lock up to come on with a push button switch, when brake pedal hit, it interups the power and will not come back on until switch hit again. I know I have seen a switch set up like this on something. cant think of what atm though
