So im looking into converting my 2004 lb7 5 speed into a 6 speed. is it as simple as buying a 6 speed valve body and tcm? if so will any year work?

same here.:thumb:Love my 6 speed-- lot quieter and a little better fuel mileage. After the sticker shock-- I am all Happy Face. :hug:
I have 265/75/16's and i trimmed the fuel at 1650rpm and added timing to 9deg's,i have seen a 2mpg increase at 65mph.towing seems about the same but then again i went from towing at 65mph to 75mph.What kind of milage gain did you see?
Could go to a 3.42 ring and pinion and you will have about the same final drive as the 6 speed.
What all do you need to convert everything? What gains did you have if you don't mind me asking?IMO, the ONLY way to convert to a 6-speed is to convert your truck to ALL 06-07 stuff. Complete LBZ/6sp swap as I did. I was messing around with the 4th Gen TCM trying to get it to work with my 04LLY ECM, as well as tried to find a 3rd gen 6sp cal that I could get to work, and finally converted over to LBZ everything (except shortblock). With the full conversion I have everything an 06 would have; Enhanced elevated idle which works much better than my LLY's winter idle ever did, tap shift, no FICM... Depending on what you were to get the parts for, you could potentially end up spending roughly the same amount on converting to a LBZ as you would on the Suncoast kit (factoring in what you would spend to get the LBZ Trans, engine and harnesses minus what you get selling the old parts). Things may have changed at Suncoast, but while there's nothing wrong with their rebuild kits, based on posts I've skimmed and conversations I've had, I wouldn't touch their 6-sp conversion kit with a 10 foot pole....
Holy old threadWhat all do you need to convert everything? What gains did you have if you don't mind me asking?
