WOW! Actually this is the first I've heard of a 6spd auto, but my research found that they are due out in 07's. Not to go overboard but probably a 4spd OD will do fine. Looking at Monster Tranny 4L65e. Ever hear of Mad Dog or Hughes? What do you think? Thanks

Went to GMpartsdirect and found that part #, good price $1871. Now I don't want to have to modify the tranny tunnel as I would with the 4l80 thats the reason I like the 4l60. Does anyone know the size/shape of the 6l80. I'm afraid that the 80 in 6l80 corresponds to the 80 in the 4l80 as far as size is concerned. I hope I'm wrong because 6 gears are more fun than 4.

As for the computer, it might be possible to reflash the one he has for the new trans, or possibly get a stand alone unit to control it.

Did the search, got specs for the 6l80e, and found some opinions that the 6l80e is lighter than the 4l80 heavier than the 4l60 and size wise somewhere in between. No definite info on if it will fit a 69. Couldn't find bellhousing info. Luna I'd apprecite specific threads if you got em. And yes from what I can gather, the electronics still need to be worked out. I thought I kept up on the conversion stuff since I've been thinking about for a while but the 6l80e was new to me and I'm definitely excited about the possibility of 6 gears, especially a 4.02 1st and a 0.67 6th. WOW I wonder how that will feel with a 3.73 rear. With a my 700R4 I have to shift manually from 1st to 2nd before I'm thru an intersection.

You CAN NOT use a 6L80E without the factory harness and computer(s). Nobody makes an after market stand alone transmission controllers for this transmission. This transmission works on a CAN-bus system and the transmission's "computer" is located in the transmission. In order for this unit to work it needs inputs from other "computers" on the network. You would have to take EVERYTHING from a donor car in order to make this work.

So you would have to take all the electronics from a a 07 corvette, caddy etc. if I understand correctly. Dang. Ok I'll just manually shift it with my B&M.
