    Has he finished the MM yet. I assume his p71 was a column shift car.

    Its like asking what's the difference between the ride quality of a Chevette compared to a Cadillac , the 4L80E does everything better shifts are much more solid and shifts are night and day!

    You know as soon as you drive the car that its not a 4r70w, there's really no comparison.

    Could you possibly make a "sticky" about the swap or post some photos? I think a lot of MM folks would be interested in this swap.

    The gates didn't seem to line up very well, close but not the same. But that could be my geometry at the trans.

    Going to be picking up a 6r80 this weekend, still swamped with work, but hope to get the swap completed by spring. I'll start a thread when I start on it,still trying to decide on whether to run the stock converter for a while or not, the whole unit only has 23k miles the 6r80 1st gear is 4.17:1 compared to the 4r70 2.67:1 I believe, should be interesting

    Spent this past weekend building my first 4l80e... Not a basic rebuild but a build... they are not for the faint of heart or wallet. We machined drums to fit extra clutches, installed a Transgo shift kit, replaced every single bushing, then fitted them all one by one by measuring them and the shaft that rides on them, then honing the bushings to the correct size. The pump was fitted with new pressure springs, relief holes drilled, new epc solenoid. pressure blow off valve installed in the valve body, billet drums, redline racing clutches, kolene steels.... almost 20 hours of work went into her... can't wait to throw it behind 428 cubic inches of Supercharged Pontiac Power!

    You may be interested in this HUB for the 6r80. If you didn't know about it.

    Thank you, it was fun. I should have taken photos of the machining and measuring process. Just did a 4r70 for our current Marauder build, basic rebuild with good clutches and steels. Also added billet drum ($800 gulp!) so hopefully years of enjoyment.

    LOL, I know right? I may be interested in doing a conversion for ya! I'd like to know a little more about the stand alone set ups and how to make the speedo / shifter / cruise control all still work.
