I use cope for my stuff. I'm sure you know but for the other guys out there.. definitely use the billet low reverse servo assembly. I had the old assembly get cocked in the bore so the low band did not release and the 2nd gear band came on. The trans instantly locked up !!!!thank god it was on light throttle! My 904 liked to burn the hi gear stock clutches, break the top thick clutch plate on the hi gear drum and crack the converter hub. I rebuilt that trans 5-6 times in the course of 15 years.probably cause i never got good aftermarket parts.Now i have a 727,that i built, with a cope reverse manual V-B, billet low reverse servo,billet hi gear drum with piston and return springs and retainer,Alto clutches,kolene steels, also the ultimate sprag. My old 904 had the 2.77 low gear set .That combined with the 4.30 gears made my mild 360 in my 74 cuda ,an awesome ride ! you are gonna love that low gear ,if it hooks up.
I did go with Cope for the parts. Both billet servos, accumulator, band strut and apply lever. Race clutches, steels and bands. Should be here Monday. I can’t wait to get this thing in the car!
Pull pan, pull valve body and then air check the system to see if any seals have “blow by (holes at front of case at front of valve body, rubber tipped air blower will act like valve body)… Never used a slide hammer for a 904 or 727, put screw driver between hubs and wiggle, pump will fall out…just how I did it when I built transmissions for a living many years ago… Also, really good video…
Hands-down, my favorite Mopar guy to watch great video bro I got a duster to that I’ve had for 30 years like I said last time I’m gonna be making videos I hope you watch them. I’m going to the track December 2.
@@Duster_Garage I think it would help your channel quite a bit. If you got on there man there’s a lot of duster guys that are responding just just the pictures of my car. In fact, I’m depending on Facebook to help get my channel rolling when I start.
There is also a lube mod you might want to do for the rear support. it involves drilling a small hole. The support is subject to galling where the output shaft goes thru it.
Thanks for making this! I have a 904 sitting the corner I want to build but dread it so bad. I don’t know very much about building them or what to look for.
@@Duster_Garage It will be good on the street, I drove one back when they said Never and no problems for 10 years as weekend cruise and drag raced. Just one thing Must have Lock out shifts , reverse is just that instant reverse lmao no whoops. oh yeah My Neighbor had Dart Sport .557 Mopar cam close to same as your set up , he ran 11.4s as a Bracket racer 6 point cage,360 "home ported J Heads 10.:1 , 4.56(spool) gears with 29.5 x10.5 Bias M/T slicks
I have a Valiant V200 1961. Does my car have the same transmission as you show here? My transmission leaks fluid pretty bad after parking 2-3 days without running Thanks

It's gonna be an animal with that low gear.@@Duster_Garage
You really do a great job with your instructional videos! Detailed and helpful. Nice job! Looking forward to your next part. 😃
Thank you very much!

Thanks man. I did get a pump out of a 727 before without a slide hammer. This one seemed extra tight though.
@@Duster_Garage I’ve run across some that I thought would never come out…hammer & screw driver time. lol

Absolutely, I can’t wait to see your plum crazy Duster in action.
@@Duster_Garage or are you want Plymouth duster’s only that’s on Facebook?
@@joshuacohn2004sounds cool but I’m not on Facebook

@@joshuacohn2004I have thought about getting on Facebook and instagram
This is perfect as I stocking parts for my 72 duster and looking into rebuilding my 904 rather than a swap
I hope this video series helps. Keep an eye out for part 2
Good video.....glad to see your stepping the Duster up a little bit.
Thanks man. I know you’re going to hate to see it go but the kick down linkage will be coming off. I’m putting a reverse manual vb in this one.
@@Duster_Garage Oh wow your going full outlaw 🤣🤣🤣
@@moparsareeverything1980😂
There is also a lube mod you might want to do for the rear support. it involves drilling a small hole. The support is subject to galling where the output shaft goes thru it.
I will look into that. I have seen that galling before. I that it was caused from towing with the cars rear wheels on the ground.
Good job dude
Thanks. I just watched your 904 rebuild vid!
A box full of goodies from CRT just arrived at my house today.
@@Duster_GarageCope Tax 😆 should be a great bang shifting unit 👏
My first reverse pattern manual vb. Can’t wait
Thanks for making this! I have a 904 sitting the corner I want to build but dread it so bad. I don’t know very much about building them or what to look for.
Cool! Stay tuned, I have more videos coming on the build. I should have all the parts on Monday.
Sorry if I’m getting a little too excited lol I just love old school duster street cars that are fast like yours!!
No worries, I love ‘em too
Awesome stuff dude we will get this thing together soon
I can’t wait
adding cheatah valve body did wonders for My transmission, I hear "A and A"
Right on, I will be installing a reverse manual valve body in this trans. Can’t wait

@@smilsmffthat .557 cam was a serious piece, I’d like to find a NOS one. I can’t wait to get this trans finished and in the car.
I have a 904. It’s definitely worn. The shift into 3rd is horrible, hahaha.
Take the plunge and rebuild it yourself man. It may be easier than you think.
💯👍🏻 Great info/video 👍🏻 👌 👏
Thanks buddy
Good video.. 😎👍
Thanks buddy
I have a Valiant V200 1961. Does my car have the same transmission as you show here?
My transmission leaks fluid pretty bad after parking 2-3 days without running
Thanks
@@sparky5431 Yes, that should have a 904 in it. It may have some slight variations compared to mine because yours is a ‘61 model.
Does the manual and automatic transmission Torqueflite 904 have the same core?
Thanks
@@sparky5431 A-904 is the automatic.
A-833 is the 4 speed manual.
A-230 is a 3 speed manual.
