November 20, 2010Yes, BIG difference!
Your truck has a 4R70W and a Lightning has a 4R100
November 21, 2010Oh I see now! Wait, no not really lol
So besides the name, wut makes it different? One can handle more horsepower?
November 22, 2010Yes,
the 4R100 is larger, longer and stronger.
November 27, 2010Phils right of course but the 4r70w can be built up to handle mucho hp.
November 29, 2010Hey 1Black.
He is right also, in most cases the 4r70 can be built to handle extra power.
A lot of it depends on the builder, the weight of the truck and the power level you try to get it to handle!
I wasn`t that lucky,
I had one of the best builders in DE that has been doing tranys for a long time.
My truck weighs in at 6000 pounds and was making close to 500RWHP.
I went through 3 ,built 4r70w tranys in 3 years!
I finally swapped in a built 4r100 and have been good since. But it was a PITA!
So, unless your making big power with a heavy truck. I`d highly recommended to build your 4r70 up.
November 29, 2010I thought I read somewhere that the 4r100 was good for 1000 ft lbs of torque in its stock form - I can be way wrong here....
But I do know the 4r100 is a nice tranny and has been around for a long while and can be made to handle gobs of power, you can build a 4r100 to handle much more power for much less money the 4r70w
while you are at it... here is who I would suggest...
