Ford Automatic Overdrive vs AODE vs 4R70W Episode 437 Autorestomod
We look at the different choices in Automatic Over Drive (AOD) transmissions. We hook up with Monster Transmissions www.monstertransmission.com and Baumann Electronic Controls www.becontrols.com . We’ll be using a US Shift Quick 4 with this install.

General Gearing:
C-4 2.46 1.46 1.00
C-6 2.46 1.46 1.00
AOD 2.40 1.47 1.00 .67
AODE 2.40 1.47 1.00 .67
4R70W 2.84 1.55 1.00 .70
AOD:
Pros:
• Now the cheapest way into an automatic overdrive for your Ford. Can be
built to handle almost anything.
• Lost of choices for mounting in Mustang.
• Can be updated with AODE parts.
Cons:
• TV cable setup can be an issue.
• Done wrong it will lunch the transmission. Mounting to other Ford
chassis will be less easy, but many ran the FMX which is a cousin to the AOD.
• Lower numerical gearing than the stock C4 or C6. Car will be a bit more
slugish off the line.
• Thin valve body is more likely to warp.
• Weak input shaft (in stock form)
Torque Limit: 450hp (average) Can be built to handle 600Plus HP.
Parasitic Draw: 45 hp estimate. We’ve seen numbers as high as 55-60 (same as the Ford C6) (C4 is our base at 28 hp).
Gearing:
1st: 2.40:1
2nd 1.47:1
3rd: 1.00:1
OD .67:1
AODE
Pros:
• Stronger than the original AOD larger overdrive band and overdrive servo.
• Stronger input shaft.
• Electronic controls for easier set up.
• Lock up converter: You can unlock the converter for acceleration or
unlock it for efficiency.
Cons:
• Costs are higher due to electronic controls and better components.
• Lower numeric ratios than your original C4/C6 equals less acceleration if
a stock axle is maintained.
Torque Limit: 450hp (average) Can be built to handle 600 plus HP.
Parasitic Draw: 45 hp estimate. We’ve seen numbers as high as 55-60 (same as the Ford C6) (C4 is our base at 28 hp).
Gearing:
1st: 2.40:1
2nd 1.47:1
3rd: 1.00:1
OD .67:1
4R70W/AOD-EW
Pros:
• Top of the line Overdrive Transmission.
• Ratios more resemble those from the C6 and C4 allowing you to run your
stock ration with no lost of acceleration on takeoff.
• Lots of choices for controlling the transmission via aftermarket shift
controllers like the ones from US shift.
Cons:
• Costs are higher due to electronic controls and better components.
Torque Limit: 506 hp (average) Can be built to handle more..
Parasitic Draw: 45 hp estimate. We’ve seen numbers as high as 55-60 (same as the Ford C6)
Gearing:
1st: 2.48:1
2nd 1.55:1
