AOD to 5 speed swap

[1990Coupe]

My buddy has a 93 gt AOD, he's going to swap to a t-5. Other then the trans, bellhousing, clutch, petals, cable an flywheel what else does he need? Can't the A9P computer work for him? thanks in advance

you mean i dont have to worry about the computer, or wiring harness for the o2 or like the neutral safty? someone told me i had to swap those too

You will need a pilot bearing for the crank, a flywheel, clutch and pressure plate, throwout bearing, a different corssmember (or a modified stock one: break the welds and slide the X-member forward), you will need to splice the two harnesses on the underside of the car to enable the backup lights and neutral safety, the interior plastic/leather for the shifter, a pedal assembly (this will be the worst part of it besides dropping the AOD), a pedal cable, some kind of adjuster for the clutch pedal (dont waste your time on the stock quadrant thing: its terrible. Get a firewall telescoping unit). Um, thats it.

AOD's can get plenty fast, trust me. My AOD'ed stang would hand my t-5'ed stang it's *** hands down. The AOD's just need a better converter (3k stall at the least) and more gear (4.10's plus) and a shift kit (to cure those slow sloppy shifts). I went the other way (stick->auto) and will never look back. To each his own.

Best of luck

PS make sure the T-5 is not one of the weak 2.3 t-5's.

Which harness are you talking about?? Is the harness for the park safety switch on the auto the same as the neutral safety switch for the 5spd? Also, should I swap the computers or not? Since we have a donor car it's not a real issue.

btw, me and 1986Stang are doing the swap.

I did the swap nearly a year ago so the details are fuzzy but I remember that the wires on the snip of harness coming off the drivers side above the selector lever had a different color scheme than the harness descending from the car floor right above it. I figured out which was + and - and then put it in reverse and see which wire turned hot. Then I did a resistence check and see which wires had a closed circuit in park and neutral.

The other connector is for the speed sensor and is on the tailshaft near the speedo cable.

Make sure you get the connector plug and a few inches of wire with the replacement t-5

Dont worry about the computer, it will work just fine. Depending on his model year, the AOD might have a cable actuated pressure regulator (you'll see 2 levers instead of one on the side of the aod) in which case the computer wasnt even involved in the first place. But if you have doubts, start the car then unplug the AOD's main harness. You wont have backup lights and you wont be able to start the car if it stalls but it should drive just fine.

sorry if I'm asking the same thing two or three times, but what I understand is that I can use the same circuit that is currently the park safety switch for the neutral safety switch? i do have a donor car, so i'm thinking things should be much easier.

i went to the ford dealer and i was told that i can just swap the neutral safety switch harness with the park safety harness.

thanks again

Yes, the automatic's park saftey switch will work. What you will be missing is the neutral saftey switch that the 5 speeds have on the back of the clutch pedal but this is not a big deal. I lived without one for 6 years on my 87 mustang. You will learn very quickly to never start it in gear =)
