First I'm shocked
@Cudafever doesn't know how to rebuild his own transmission! Certainly rebuilding that Holley carburetor was much more intricate...
So first of all let's just start by stomping out this automatic transmission Boogeyman. Probably perpetuated by transmission Folk who will tell you that there's things you don't know and say all kinds of Boogeyman scary stuff to make you not try it yourself... remember the old days the tranny starting to slip so you better sell the car?..
First off when I rebuilt my first transmission a couple years ago I had no book and just some YouTube videos and a very gracious member sent me a Factory manual DVD...
Second 99% of my tools are from Harbor Freight... There was only one special tool needed and I actually used a bent piece of c bar and my vice in lieu of it... If you want to get super crazy you might buy some bushing setting tools which is just a round piece of metal the same size as the bushings to pound it in straight..
Taking off the tail housing I think was four bolts and a c clip. Then tighten the front band adjuster which is the only bolt sticking out with a set screw so the guts don't fall out when you pull the pump off the front... Valve body is the two or three screen bolts and the 10 bolts that hold the valve body on... The standard way to take the pump off the front is to take all 6 bolts out and to the side boats have inner threads to grab it by and slide hammer it out which I did that like a rookie the first time that watch the video and a guy just stuck a screwdriver from behind and gave it a whack in the pump flew out... then you remove the front drum by loosening the band and the rear drum comes out and then you can pull the entire shaft out and that's it... You take the snap ring off the front drum and replace the Rings clutches and seals it's obvious when you pull it off. You do the same to the rear..
I went ahead and put a transgo 3 shift kit making it a full manual shift transmission...
It was by far the best automatic transmission I'd ever driven... it was neat to look at my friends when I shifted the transmission and they look at me like wow that is the way it's supposed to shift nice crisp not banging but crisp and right on cue..
of course this blew my head up and gave me confidence to do my buddies 350 turbo for his 6. 6 Trans Am.. it was a little more difficult as it just had twice as much of everything it seems like for what seemed like the same results and he's enjoying his ta...
this hillbilly I watch new like 13 videos and they're dry very dry but funny because well he's a hillbilly.. so as far as space he was doing it in his kitchen LOL...

You can just see used a 2 foot by 8 foot sheet of plywood that I had ripped at the hardware store and set it up on two chairs as a workbench for this temporary project and it worked perfect...
Now if anything ever goes wrong with the transmission you'll know exactly what it is and why and how to fix it..
It was about $120 for the rebuild kit and about $85 or so for the transgo stage 3 shift kit...
I just haven't had the luck that you guys have had and i know why now......
Any ways here is the story.
Rebuilt my first 727, and you are right, with a couple of home made tools it was painless
Lasted until almost the end of the season, then failed.(this was when i was racing every other week end) at the now defunct RMR Raceway in SLC Utah.
Sooo i decide to take it to a "professional" aka a transmission shop!
Cost me a boat load of money and it failed yet again half way threw the season. Took it back and he adj the band and said that was all he could do because i race the car there was no warranty at all. The band adj was just being nice.(the band material was gone off the band so now the timing was real bad between the 1-2 shift lost 2nt gear before i got home that night!
My buddy had this guy build his 904(actually was a 998???? the one with the low first gear set) any ways, my buddy had been beating on his 68 dart that when into a 73 duster and work GRATE!
So, i had him rebuild my spare 727................Yup half way threw the season, it failed( this was my daily driver at the time.
There was a guy at the track that had a dragster with mopar big block and was running a 727 behind it. every time i failed a transmission i keep hearing about this guys transmission skills.
Soo, I Get ahold of him, drive to his house, drop off the transmission. He tells me that i should run a manual valve body in it if i'm going to race it........so i say ok and that i was going to build a new eng(I wasn't) and would it hold up to 500 Hp(stock 340 with a cam) He says no problem!!!!
That next year it live thru the hole year and i placed 17 at the end of the year.
The next year i was in 2n't place, the last race of the year but choked and ended up 4 for the year.
I have not raced hot and heavy like that and chase the point like that sence.
HOW EVER, that transmission was built in 1997....late 90' any ways...................STILL RUNNING STRONG TO THIS DAY!!!!!
CAN I REBUILD A 727 AND MAKE IT LIVE???? Yes i think so, because my failure was in the improper kick down linkage set up on the transmission.......Manual valve body eliminates that problem. All of my problems was 2nt gear band burning up.
When this 727 fails, will i rebuild it myself........................Not as long as that old man is still alive. If not then i will probably give it another go.
So J par
There is your answer, to your "Shock" and disbelief of my skills......................................
