MT82 to 6R80?

[Jenkins]

I am wanting to change my Boss from a stick to an auto. I talked to racerat and she pointed me in the right direction but i was wandering if they make a performance automatic i could go with instead of the 6R80. Or would the auto hold up to about 700rwhp cause that is where i am taking my car. Thanks.

You need a Circle D converter and the Greddy Stage 2 upgrade kit for the trans. You'll be good to go for 700+ :beer:

Do you know if anyone makes a conversion kit for this or would my best bet be looking for a totaled auto car and pulling its tranny?

Im looking at a 800 hp capable 4r70 conversion. Comes with controller.

Performance Automatic Mustang 5.0L Coyote 4R70w Street Smart Transmission Kit SS45103

the add says 650hp. i talked to the PA and they under rate it for some cushion. he said it will take 800hp all day long.and it has a lifetime warranty

 

[Jenkins]

Is that everything i would need going from a stick?

 

[turbosha]

this is a stand alone system for any car with a coyote.so it will work in our cars. the cross member and driveshaft is the only things im not sure of. im still trying to figure it out.

i was looking at this also. just have to get everything else seperate.
still cheaper than a factory 6r80

I read in an older thread where a guy detailed his sway from stick to auto that the drive shafts are the same just so you know but thats just what i read.

cool

I've been considering that 4r70w conversion kit but don't know anyone who has done it... Does anyone know if everything needed is included in the kit?... Also how difficult would the install be?

Someone on svtp said the tranny out of a raptor is stronger than what comes in the mustang.

Probably costs a fortune too though

In this video I can't tell if he get into 4th gear or not... I wonder what the top speed with this 4r70w kit would be in each gear with 4.10's? 137mph in 3rd would be insane I'm guessing he was in 4th?

i only heard 2 shifts. 3 rd gear in the 4r70w is 1:1. 4th is overdrive.

That maybe be true. Just giving the op what they asked for.

Yea I couldn't hear him shift into 4th but trapping 137 in 3rd? That's crazy
