Default 5.4 4r70w transmission install question.

So I have the 5.4 4r70w transmission combo. I'm mating the two together. Torque converter has 4 studs coming off of it evenly spaced, flex plate only has 4 holes on it so they line up perfectly. My concern is drain plug/counter weight from you tube videos it shows drain plugs coming through the flex plate instead of being on the outer ring.

That dumb factor being taken away to help line it up, does a particular stud need to line up and come through a particular hole on the flex plate? If yes how do I know which? I just dont want to get it all together and that little weight breaks something or causes undue vibrations.

Thank you in advance

When I installed my rebuilt 4.6 with the 4r70w I just bolted the tq back to flex plate. No problems.

It does not matter which stud on the converter lines up with which hole in the flex plate. Both are balanced independently of each other. The bigger worry is making sure the torque converter in "seated" fully into the transmission. Make sure when the block and trans. Bell housing are fully mated to each other and the studs are through the holes in the flex plate that you can still "wiggle" the torque converter before you instal the nuts. Good luck

Default new torque conv. verse an old torque conv.???

Whatís up with Ammco Trans.??? Did any of you have problems with them ?? My 2008 f-150,144,000 miles, 4◊4 tranny blew,took to dealer, wanted $3900 to replace,no way so i took it to Ammco,they been around long time so i felt safe. Price $2800(with 3yr warranty)had them do it.picked up truck,drove 40-50 miles then Trans error came on & would not shift,had it towed back to Ammco,couldnít find anything wrong,said it was just a computer glich so they re-set it. Drove 230 miles in 2 dayís,did it again,towed back,this time,they replaced trans. they got from ford,picked up truck, drove 22 miles & it blew again. Towed back,3rd time. This time they said torque converter blew(on receipt said new 1 put in with new trans.).My ? is- do you think they just said they put in a new torque & used the old one?? How would you know?? you canít see it. I think thatís what they did,itís $400 on my receipt(for nothing if they did that). I think,the new trans. used much more force & the old torque couldnít handle it & shattered it, What do you think? A new hunk of steel is tough to shatter but a torque 6yrs.old,with 144,000 on it would weaken it, what do you think?? Now towed back to them today(6wks later)because trans. cooler line blew,are you kidding me,rotted out,shouldnít they of known they were rotted when they disconnected them from the old trans.?? They said they were trying to save me money,i thought they came with a new trans.,they donít,so i said to them,thatís bull****,i said, every trans. you put in,every customer (like me) think new lines come with it!! When your paying $3,000 for a new tranny, there isnít one customer who would say no to changing the cooler lines(under $40.00)while the old tranny is out,would any of you?? All this crap dealimg with Ammco went from 2-3 day fix to 15 days(cost me ($930.00) for a rental,& now have to rent another car because of the broken line. They Suck!!!! thanks

Sorry you're hav ing such a hassle with your trans. I don't think new linew would come with the trans repacement, but if they're that bad, the shop should have mentioned that and given you the option to have them repalced
