OK - I have a 727 TF and a master rebuild kit. Let's here from all you tranny guys. I want to rebuild it myself. I have never done any more than a shift kit before, so this will be my first shot at the guts. What am I getting myself into? I have rebuilt 5 or 6 motors with success, overhauled a 70hp International Tractor and can be pretty dangerous with a book! LOL
Seriously, I am a certified millwright and have passed courses in hydraulics, lubrication, power transmisson, and many other subjects. I am no newbie to a set of tools and have been successful on my past attempts at a new subject. Should I go for it or just leave it to the pros? Money isn't the issue, I would just like to be able to do it myself.
Don't be shy, let me know what you think.
(yes, I do have a good selection of tools, solvent tank, air, etc.) I figure if a guy can kearn to rebuild a motor from a book, why not a tranny too.:read2:
 
What your getting into is in my opinion the absolute easiest trans. to rebuild.

When you rebuild it make sure and replace all the thrust washers and bushings and set all the clearances properly which is a lot tighter than the factory serv. manual specs. Not knocking Ma Mopar but the specs are unbelievably loose in the service manual. Always air pressure check each item (clutch packs, servo's) before and after final assy. (but before you install the valve body) that way you know it'll all work right in the end. And buy a shim pack to shim up the excess play in the gear train assy. so it's not slapping all over the place. I buy most of my parts from www.bulkpart.com as their prices are about the best I can find and they have a nice selection of stock to high perf. stuff.

My suggestion is to buy this book (see link below) and use the specifications it says and your torqueflite will not only work better but last at least twice as long

[ame="http://www.amazon.com/Torqueflite-727-Transmission-Handbook-HP1399/dp/1557883998/ref=sr_1_1?ie=UTF8&s=books&qid=1269235144&sr=8-1"]Amazon.com: Torqueflite A-727 Transmission Handbook HP1399: How to Rebuild or Modify Chrysler's A-727 Torqueflite for All Applications (0075478013999): Carl Munroe: Books@@AMEPARAM@@http://ecx.images-amazon.com/images/I/51DRYYSVH4L.@@AMEPARAM@@51DRYYSVH4L[/ame]

It's chocked full of great information about the Torqueflite and improvements you can do. The guy is a great writer too. Very easy to understand. Ton's of pics of the different variation's of torqueflites built.

If you need any information or just want to BS about them feel free to PM me and I'll do my best to help. I've been doing them for over 25 yrs.
 
Technical Videos #1205 727 TF

Great source and has many shortcuts that others say you need special tools.
 
Somethings very odd with that link. When I click on it this page comes up again?? Had to manually type it in to get it to work. LOL

Weird. Now it works right????

hey..Are you saying I am copying copyrighted material?????

The video is excellant..the guy walks you thru tear down...inspection...re-assembly of trans..

you can stop it rewind it...the books are nice....what watching it on video is better..

About 6 yrs ago I had never rebuild a trans...Now i have done, 727s, 904s, 46RH, 46RE, 42RH...
 
The 727 video looks like a good buy but are the specs the same as a 904? I wouldnt mind getting the video but I would like the specs to be there :D
 
Thanks for all the input. I guess I will give it try next week while I am on vacation. The shim pack you spoke of, is it for a 727 TF or just a general kit? I would like to have all the stuff availible when I start. Any special tools I will need? (I have a full compliment of hand tools, air tools, and dial indicators.)

Their specific to the 727. Here's a link

http://www.bulkpart.com/Merchant2/m...39A&Category_Code=A727washer&Product_Count=15

The only 2 things I can think of that you didn't mention is a set of flat nose outside snap ring pliers to unlock the big snap ring that's in the tail shaft and I made a tool to compress the clutch spring pack. It's used in conjunction with a press. It's not real pretty but works great. Also works on a few other trans clutch packs. So far I've used it on a 727 and A500 Chrysler and 350 and 400 Turbo Chevy trans. Here's a couple pics
 
I hope that link works. For some odd reason the last couple days links haven't worked right for me. If it don't go to www.bulkpart.com and look under Chrysler 727 transmissions then thrust washers and it's the bottom one on the thrust washer page.

Hell that looks like a Snap on tool compared to the one I made. I'm not home to take pictures but I used a tool meant to compress the steering wheel locking plate on a column, the one that looks like a horse shoe, I then ran a piece of all thread thru it with a lage washer at the bottom. This way when you run the nut down it will hold it in compressed state to install the snap ring. Cheap but works great.

I'll second that. I usually just lay everything out nice and neat on the workbench as I'm taking the transmission apart. Then, just put it back together in the opposite order after you get the new stuff put together. A factory service manual is handy too for the exploded views.
 
OK- I'm commited now, I just ordered the book! Anyone using the Trick Shift kit from B&M? I use to use them in my Chevy's. Manual Valve body instead? I am not going too crazy, just a strong running 318, 2200-2800 stall. The B&M shifter is already in the car. Might go stroker motor later, but if I do I'll do more then.
 
They're easy. Did my first one at 19. Have done a 904, and a C4 since then also. The FSM from the library is what I used.

LOL... I've seen them like that before and they work fine too. Since I have a hyd. press I made one to work with it.

I don't know what B&M offers now days for torqueflites but I can tell you their older kits were so inconsistent that I stopped using them in the early 90's. Sometimes they worked ok and sometimes they caused severe overlap. The only trans I ever do that I have good luck with a B&M kit on is a 350 Turbo. For a torqueflite I recommend a Trans-go. They have 3 different levels so you can find one to suit you. The TF-3 converts your stock valve body to a manual valve body.
 
OK - Book should be here today, and I degreased and wire wheeled the tranny last night. The thing cleaned up so nice I should clear it! LOL Hey, there's an idea. A polished transmission! I did remove the casting flash.
I might have to swap the tailshaft (it looks really long, but I have to check the one that is in my car) How much does this complicate my re-build? Also, I see tran-go is the way to go. How is the stage 2 kit? Does it give me manual control? Is stage 3 too radical for the street?
 
All car transmissions are the same length so you shouldn't have to swap the output section. Only 4x4's, 1 tons, and some motor homes used a different output shaft section.

stage 2 does give full manual control but keeps the automatic shifting feature. Never used a stage 3 so I'm not sure on it except I know it's full manual shift only.
 
I did my 4l60e in my camaro at home, Also did a nice little write up on it. This 4l60e makes a 727 look like a cakewalk. If you are knowlegable with how a tranny works, using feeler gauges for clutch pack clearences, and getting parts clean you should be fine.

Like some of the guys said get a good tech manual for all the specs and step by step, I also ordered a video, sometimes they help out even more.
