A4LD to T5 Swap in 87-93 2.3L Mustang
(not to be confused with an AOD-T5 5.0 swap)
 

Performance Parts List Price
Clutch (High Performance 6 puck) 120
Pressure Plate (Hi-Pressure 88TC) 40
Clutch Quadrant (3 hook, Billet Aluminum) 34
Clutch Firewall Adjuster (Billet Aluminum) 34
UPR Blu Thunder Shifter (Short Throw Billet Alum.) 125

This article is specific to the 2.3 Mustang.  With minor changes, it can be used to complete the same swap on a 5.0 Mustang. 

I chose to do this swap for three reasons.  The first was because I was sick of the automatic sucking all the power from my car.  The second was because the auto tranny wasn't strong enough to handle the power my new turbo motor was putting out.  Had I not done the turbo swap, I don't know if I would have ever taken the time to swap trannies.  The third is because I wanted the ladies to ask to drive my stick and to teach them how to handle the stick. :) 

Above is my parts list.  This is only the high-performance pieces I chose to buy.  I was fortunate enough to get the transmission and parts listed below from a Turbo Coupe that my sister "donated" to my cause.  I would highly recommend the Quadrant and Firewall Adjuster listed above.  They are far superior to the factory plastic, non-adjustable units that are prone to breaking.

Before you ever think of even beginning this swap make sure you  locate all the necessary parts and accessories listed below.  If you can find a complete car then it will simplify the process greatly.  All you need to do is get everything that is manual transmission specific (different than the auto trans equivalent).

Parts & Tools


Removal Of Automatic Transmission: 2 hours

1. Jack up the car as high as your jackstands will go.  If you still can't fit under the car, you either need to go on a diet or need bigger stands.  Put a jack stand near each wheel.
2. Remove driveshaft.  Watch as all the fluid runs onto the floor, making a big mess.  If you have a spare yoke that you can put in the tranny it will prevent the fluid leak.
3. Disconnect the throttle valve cable and speedometer cable as well as any plugs that are connected to the trans.
4. Remove the tranny cooler lines.  Don't be afraid to cut them if necessary.
5. Remove the inspection plate from the front of the tranny and remove the torque converter from the flex plate.  You will need to rotate the engine to get to each bolt.
6. Put a floorjack under the center of the tranny and remove the crossmember.
7. Use a box end wrench to remove the bellhousing to engine bolts.  You may find it easier to access the top bolts with a long extension.  I found it easier with a wrench.
8. Remove the transmission.  You will have to wiggle and pull back to get it to pop loose.
9. Pull the tranny out from under the car.  You may have to jack the car up even higher before it will slide out.
10. Install inspection plate to keep converter in place.


Shifter Removal: 20 min.

1. Remove the rubber boot that surrounds the automatic shifter.
2. Remove the plastic shifter bezel.  It will look like it's about to break and then the clips will let go and it will come loose.
3. Unbolt the shifter base and unhook the cable.
4. Remove the shifter.  It will take some force but the base will finally slide through the console hole.
5. Now you need to make room for the T5 shifter.  You need to lengthen the front of the hole by 1/2".  I have found that cutting a 1.5" by 1" slot in the back of the hole, directly in the center makes installation of the tranny much easier.
 

Removal Of Pedal Assembly: 2 hours

1. The first step is the remove the driver's side seat and clear out the area so you can lay on your back for most of this procedure.  Once that is complete you can begin the removal of the pedal assembly.
2. Remove the plastic cover below the steering column and lower dash.
3. Remove the hood release cable and bracket.
4. Remove the 4 bolts that hold the steering column up.
5. Lower the steering column.  Unplug the wires as needed.
6. Remove the steering column.  All you need to do is remove the bolt on the steering shaft under the hood.  Once this is removed you can pull the column out of the car.  I did this because it simplifies the removal of the pedal assembly, if you choose not to do this you will need to let the column lay beside/on top of you while you lay under the dash (not a real enjoyable experience).


(This is what your steering column should look like once removed.  If it's different than this, you screwed up)

7. Remove the 4 nuts from the brake booster.  You will need to use a long extension to get to a few of the bolts.
8. Remove the two nuts from the top of the pedal assembly
9. Remove the brake booster rod from the brake pedal. Make sure you know how to put it back together.
10. Get out of the car and get under the hood.  Grab the brake booster assembly and pull it forward as far as you can without crimping anything.  You may need to put a screwdriver between the firewall and booster to hold it forward.
11. Get back under dash and wiggle pedal assembly loose.  There is no easy way to do this.  You will just have to fight it until it comes out. Once you get the assembly loose you may find a few connectors or wires that you need to unplug to remove the pedal assembly.  At this point your progress should look like this:


(Notice the big mess of wires seen here, if you want to impress your friends make sure they see the car like this...they will think your nuts:)

12. Try to remove the speedo cable from the back of the speedometer.  You will need to use a pair of long 30 degree needle nose pliers to try to reach it from under the dash.  If you can't get it loose from under the dash you will need to do the following:
- Remove the gauge cluster cover.
- Unplug the wires.
- Remove the gauge cluster. There is one plug on each side and the speedometer cable holding it back. Don't force the gauge cluster away from the dash too hard.  If everything is removed, you shouldn't need to force it.  Once you complete step 5 you can put the gauge cluster back together.


(I took the dash apart just so you would have an idea of what to expect, I got the speedo cable hooked back up from below, really I did!)

13. Pull the speedo cable out from under the hood.
14. Remove the rubber grommet that is in the hole the speedo cable went through (see pics below)..


(Note: big red arrows won't be painted on your firewall:)  As you can see, the speedo is in it's new location and the clutch cable is installed in this pic.)

15. Install the grommet in place of the one approximately 2.5" left and 1" above the old hole.  Install the speedo cable through this new hole.
16. Run the speedo cable back to the speedo and hook it to the back of the speedometer.


Installation Of Manual Pedal Assembly: 1 hour

1. Wiggle the pedal assembly into place.  Make sure you slot out the holes in the brackets that go to the steering column bolts as well as slot the two middle holes and two of the steering column bolt holes, it will make it much easier to install the assembly (see pics below).  If you don't slot the holes like shown below, you will have a hell of a time trying to get the pedals installed.


(Here is a comparison of the pedal assemblies.  If your manual one isn't rusty like this it won't work...J/K:)


(Make sure you slot this hole, otherwise you will cry uncontrollably for hours after fighting to install the manual pedal assembly:)

2. Remove the screwdriver between the firewall and brake booster.  Install the 4 nuts that go on the brake booster bolts.
3. Install the nuts on the top of the pedal assembly.
4. Install the clutch cable in the hole the speedometer cable came out of.  You will need to drill a small hole for the screw to hold the housing on the cable to the firewall.
5. Locate the clutch neutral safety switch plug under the dash.  It is located above and to the left (towards driver's side fender) of the clutch pedal.  It will be taped up to the main harness.  You can look at the plug on the clutch pedal to see what it is supposed to look like.
6. Install the brake booster rod on the brake pedal.
7. Install the clutch cable and hook it to the quadrant.
8. Install the steering column and plug in all the wires.  Make sure everything is plugged in, you don't want to take it back apart later.
9. Install the hood release cable and bracket.
10. Install the plastic cover below the steering column and lower dash.  Now is a great time to vacuum your carpet.  You don't have too many opportunities to get under the seat.
11. Install the driver's seat.


(If yours isn't this pretty when it's done then too bad, better luck next time:)

Installation Of Manual Transmission: 2 hours

1. Install the pilot bearing.
2. Slide the starter index plate into place.
3. Install the flywheel.  Torque the bolts to 85 ft/lbs.
4. Slide clutch disc into place and center it using a clutch alignment tool.
5. Bolt the pressure plate to the flywheel.  Torque the bolts to 25-30 ft/lbs.


(This is an 87-88 TC pressure plate, the early cars look slightly different.  If your clutch disc and pressure plate  isn't centered like this you will be a tired SOB before you get the tranny installed:)

6. Install the throwout bearing on the tranny.
7. Install the tranny/bellhousing assembly.
8. Install the cross member.
9.
Change the Auto's neutral safety switch to a T5(Z)'s reverse light switch. The Auto's wiring harness for this consists of 4 wires. In most cases, this section of wire can be replaced with a simple 2-wire T5 harness. The 2 wires go to the reverse light switch and the other 2 wires are connected with a jumper wire already on the harness. The colors are the same so it's easy to see what colors need to connect to what.
10.
Hook the clutch cable to the tranny.
11. Install the speedometer gear in the tranny.  You will need to grind down the "nipple" on the end of the gear to make it about 1/4" shorter.  If you are using the 5 speed car's rear end as well then you can just use the manual trannies speedo gear.
12. Fill the tranny with Dexron auto tranny fluid. You will need to use an oil pump from under the car or try to fill in through the shifter hole.
13. Install the driveshaft.
14. Install the shifter boot, handle, knob, and bezel.
