The SD's use the 6R140The 6R80 trans on our trucks is also used on the F250 & F350 super duty trucks. . . they should handle 500 hp easily. I don't
plan on stretching the envelope that much, I'm happy with modest gains myself
The 'boost makes the same or better torque than the 6.2....I was misinformed, but they are capable of putting 1000 HP to the ground with mild modifications for the Mustangs.
The 6.2 V8 uses the 6R80 though
call and talk to Circle D Specialties.I've been looking into tranny mods for the last few hours. I'm really interested in a higher rev torque converter like the hemi guys are running. Apparently it makes for huge gains in the 1/4, but I don't know if it'll still be suitable for towing.
No.... The 6r140 is used the 250 and 350 trucks. I am a trans builder for the dealer and thus far this has been a phenomenal unit...they got a ton of clutch insideThe 6R80 trans on our trucks is also used on the F250 & F350 super duty trucks. . . they should handle 500 hp easily. I don't

I got my info from the Full Race website, where they state the following:No.... The 6r140 is used the 250 and 350 trucks. I am a trans builder for the dealer and thus far this has been a phenomenal unit...they got a ton of clutch inside
The 6R80 is currently used in the mustang and f150. The current f250 uses the 6r140 transmissions. I guess they mean that's basically a scaled down version of the 140, but it's not the same tranny.I got my info from the Full Race website, where they state the following:
"The use of a properly geared six-speed transmission provides improves fuel economy 4-6 percent. This F-150 '6R80' six-speed is a solid and proven transmission from the SuperDuty F-250 and F-350.
6R80 also features a Tow/Haul mode and FX4 includes "Hill Descent Control" from the Raptor."
I believe that to be a typo or an incomplete thought that wasn't caught.I got my info from the Full Race website, where they state the following:

The 6.4l powerstroke utilized a 5-speed transmission, so it's not that either. It may be the transmission from the transit van? idk.The 6R80 is currently used in the mustang and f150. The current f250 uses the 6r140 transmissions. I guess they mean that's basically a scaled down version of the 140, but it's not the same tranny.

he 6R140 is just too big. id bet it it weighs in at 75lbs more that the 4r100. i have to use a cherry picker to get em on the jack. thats the only tranny i can say that about. the insides are insanely large. the ford manual wants you to use cherry picker to remove the geartrain for repair. its that heavy! the hard parts are massive. id be comfortable putting it in a kenworth...but all in all its just too big/heavy...but the durability is definitely there. the 6r80 can definitely take what the lightning can dish out. its a smaller version of the 140. its got a massive planet that looks to be indestructable. i was amazed when i saw how much clutch was in this tranny. the steels are nearly .120 thick...and there still 6 plus clutches in each section. this is unheard of. im sure this can take a ton of power reliably. also the drums are GROB....a badass cold rolled steel that dissapates heat very quickly. i believe it to be a bit lighter than the 4r100 but not much. if you were dead set on a 6 speed swap this is your tranny.... now both these units have that crazy low 1st gear......to me this would be a detriment for any built truck now that TCI 6 speed.....come on! 8K for a trans only good to 800hp......gimme a break! its a reworked GM 4L80E..... |

The mustang and s/c raptor boys prove that it can handle the power everyday!From the Ford Lightening:

now both these units have that crazy low 1st gear......to me this would be a detriment for any built. theres no way youre gonna hook it when it counts......this being said i think the 4r100 is the overall winner here.......id just keep it. for the cost of a swap with all the supporting hardware i dont see the benefit here....truck
