Mach1 Driver 560 Report post Posted February 4, 2018 I've been leaning toward a 4R70W because it bolts right up to a 351W, but wonder what has been done lately with the 6R80? Its a 6 speed Ford that is wider for most of its length and about 100 lbs heavier, but a little shorter. The only hit I got in a search here was behind a Coyote in 69 Mach with extensive metal rebuild. Does anyone know of a more conventional swap of one of these beasts into a classic? My guess is that the tunnel is too small. Quote Share this post Link to post Share on other sites
ralt962 11 Report post Posted March 17, 2018 I might be able to get some dimensions of the 6R. But I do know the electronic controls of the 6R are much more complicated. The torque management system is buried in the PCM. Typically they need to work together with the engine controls as it reads the torque output of the engine, based on throttle position and the Mass air flow sensor. The 4R would be an easier fit. If you have the Coyote engine and the PCM the 6R would be a good match. Worked at Ford in Trucks for 37 years. Now working for Roush. Was never a calibrator but worked with them extensively over the years. Quote Share this post Link to post Share on other sites

Thanks, but since its that complicated I'll stick with the 4R70W and 351W 1 RPM reacted to this Quote Share this post Link to post Share on other sites

The engine is mapped with speed load points with the mass air flow sensor before the throttle body. Along with the output at the O2 sensor and the injectors they know what the torque is and try to optimize the trans shift schedule. Way too much for what its worth. The 4R will work great. 1 1 mwye0627 and Mach1 Driver reacted to this Quote Share this post Link to post Share on other sites

Correct, I too worked with Ford calibrators for over 20 years... They use the output from several sensors to calculate what they call "Inferred Load", which they use for several engine management functions... Before the days of Wide Band O2 sensors, they used Inferred Load to approximate Volumetric Efficiency for Fuel Management. The Inferred metrics are derived from extensive dyno testing which allows the calibration engineers to create "Maps" and "Tables" to control Fuel and Spark under almost all operational and environmental conditions!!! 1 Mach1 Driver reacted to this Quote Share this post Link to post Share on other sites

Stangn 1 Report post Posted April 16, 2018 The 6r80 in my 13 GT is a beast! Trans doesn’t have bands it’s all clutches and planetary‘s. Bands fail because of limited clutch material and hydraulic pressure to grab the drum, that’s the death card of a 4r70 or aod/aode. Bad thing for 6r80 is electronics to run and it’s bellhousing pattern is only for modular engines. Quote Share this post Link to post Share on other sites
1969_Mach1 333 Report post Posted April 17, 2018 The 4R70 is a good trans. Our old 1996 Mustang GT had. It went over 300K. Still worked fine when we got rid of the car. I serviced it regularly and installed both a shift improver kit and auxiliary cooler when the car was fairly new. I've installed both Transgo and B&M shift kits or shift improver kits on those transmissions. In my opinion, the B&M kit has worked better for that particular application. However, I don't think the 4R70 was ever installed behind a 351W. To the best of my knowledge Ford always put the larger E4OD behind 351W and larger motors. 1 RPM reacted to this Quote Share this post Link to post Share on other sites

Please correct me if I'm wrong, but I've never heard of the E40D being used in a classic Mustang. The 4R70W is the latest and greatest version of the AOD, supposedly redesigned to remove the shortcomings of the AOD and AODE. The AOD, AODE, and 4R70W are one of the few ways to get an overdrive in a classic, and it bolts right up to a 351W. Wikipedia says the 4R70W was used on these cars, but it doesn't mention the engine in front of it (notice that Mustang isn't on the list): 1993–1998 Lincoln Mark VIII 1993–2003 Ford F-Series 1994–1997 Ford Thunderbird 1995–2004 Ford Crown Victoria 1996–2001 Ford Explorer 1993–2004 Lincoln Town Car 1994–1997 Mercury Cougar 1995–2004 Mercury Grand Marquis 2003 Mercury Marauder 1997–2004 Ford Expedition 1997–2001 Mercury Mountaineer 1996–2004 Ford Mustang Quote Share this post Link to post Share on other sites

1969_Mach1 333 Report post Posted April 17, 2018 Back in the day of pushrod motors, the 5.0L and 5.8L (302 and 351W) in F-150 trucks and Bronco's, etc., the 5.0L models got the 4R70W trans and the 5.8L models got the larger E4OD trans. In 1997 when Ford went to modular motors in trucks I think they all got the 4R70W. It has always been that way with auto transmissions. Ford cars and trucks with a 5.8L (351W) got a larger automatic trans than the 5.0L (302) or small motors. Even these classic Mustangs. Mustangs with a 302 got a C4 and Mustangs with s 351W got the larger FMX. I can be wrong, but in my mind I think its because the 351W makes a lot more torque than a 302.

Monster rates their E40D heavy duty at 350hp/600tq and the super duty at 450hp/900tq. Interestingly they don't give torque numbers but have 3 versions of the 4R70W: mild= 280hp, heavy= 460hp, and super= 600hp Quote Share this post Link to post Share on other sites
Darkman 2 Report post Posted October 24, 2019 The 6R80 has 6 speeds and handles much more torque and horsepower than the AODE/4R70W. The rpm drop between shifts is much less. Adapter kits to bolt up to small blocks and FE's. I'm exploring putting one behind my 69 428 CJ Mach 1. I'd like to see them side by side to see how close the tunnel will be. It's supposed to be wider but not taller. In 2011 Ford removed the ECM from inside the 6R80 and now there are stand alone controllers available. Torque converters and internal parts are available. Can easily handle 1000 horsepower. Hoping this will work for my car Quote Share this post Link to post Share on other sites
stangman69 17 Report post Posted November 7, 2019 What about using a stand-alone aftermarket transmission controller al la https://www.usshift.com/usq6.shtml? Quote Share this post Link to post Share on other sites
ralt962 11 Report post Posted November 24, 2019 See notes at the start of this string. 6R80 is a good trans. At Roush we still use it in the Mustang that is tuned to 775HP. But we spend time on the trans shift schedule. The calibration is key to making it run smoothly. Its dependent on the engine control system and torque management. I'm not familiar with the stand alone controller and how they make it work. As stated before its a torque based shift schedule which reads a map of the engine based on the throttle position sensor. With out the other engine sensors I"m not sure how they would make it work. Quote Share this post Link to post Share on other sites
