Rebuilt 727 Sources

[saforwardlook]

That's not an option for me, I don't have a 727 tranny yet, but I'm gonna need one with my 383 engine that is going into the car. Does that guy have transmissions for sale, or repairs only?

About that kickdown adjusting, what could be wrong with my 904, shifts up like it should, but won't shift down from 3rd until the speed is 10-15mph?

I don't know if Don has transmissions for sale, but the shop that twostick mentioned sure does. And they too are probably good units coming from a race shop. But I don't know for sure about them.

You mean that if you floor the throttle you won't get a 3 - 1 down shift until 10 - 15 mph or that you won't get partial throttle kickdown until you are in that speed range? What year is your 904? While you might be getting adequate upshifting, you still might not be getting the throttle lever to move fully rearward at WOT which would inhibit downshifting any earlier than at low speeds. Part throttle downshifting was a feature on 1971 and up torqueflites only. I know that is true on the 727s and probably the 904s too.

That's a good question about 904 transmissions, and the part throttle. I thought they employed it earlier with the /6 engines anybody know for sure.

No I didn't mean any of the kickdown stuff, I mean when I'm slowing down the transmission won't shift to lower gears from 3rd until my speed is that 10-15mph. Asked because that's way too low speed to drive at 3rd, I'm afraid that it'll burn my transmission, so I just manually shift to lower gear in that situation to avoid driving with 3rd gear at too low speeds you know. I believe that is the original transmission so '70 it is.

Sounds normal for a 70 trans the part throttle downshift didn't show up till 1972 on 727 the 904 had it on the /6 early on Thats why I was asking if anyone knew is it was standardised earlier on say a 318/904

Got it, thanks a lot for the info. I must be doing a big favor to my transmission by manually shifting down or what!

Picked this up the other day...this is the mildest shift kit offered by Transgo. This company received a lot of acclaim on the Allpar site on the page that talked about the "Legendary Torqueflite". The founder, Gil Younger, was known as "Mr. Shift". Sounds like he was quite the well-respected go-to guy for trannys.

This kit isn't really supposed to make shifts much firmer, according to various sources I've read, just improve the flow of fluid, prevent converter drain-back, improve oil flow to bushings, correct soft shifts. As an added bonus, it'll allow the fluid level to be checked in park.

Tranny is working fine now. But figured I'd install this kit over a weekend and hopefully keep this 727 in service for a few more thousand miles, maybe 50. currently at 93k.

Part throttle kickdown was actually introduced in the 1971 models, not 1972 for the 727. I really do not know when it started in any of the 904s. One of my few small blocks is my 1973 Monaco with a 360 2bbl, and that is the extent of my small blocks. And I must say that 360 2 bbl rocks!

I agree that your downshift pattern when slowing down sounds normal to me too. Part throttle kickdown was intended to alleviate driving in 3rd at low speeds, since tipping into the throttle just a little at low speeds will cause an automatic downshift.

Speaking of which, this is one of my current projects. I sure hope I remember how to put it back together...

It looks a lot worse than it actually is. The factory service manual is actually pretty good in describing the sequence and the adjustments. It sure helps to have some of the factory service tools for some of the clutches and such. I personally would not take apart the valve body unless there was something wrong that suggests it as a culprit (rare). Just clean it and save yourself some time. I used to take them all apart until I realized it was pretty much a waste of time.

One caution, be sure to replace the o ring on the kickdown lever shaft as the service manual is skimpy on mentioning that, and you don't want a leak from it down the road (it will leak out the back of the case).

Put the long part in first, put the rusty part in last. Done.

And what do we do with the leftover parts?

Weld them together along with a cast crank and make a custom mailbox post out of them.

One of the best guys on the planet for 727's. Keith is well known on the other Mopar boards. I know him personally...one of most knowledgeable 727 guys on the planet. I bought a bunch of txsm parts from him a couple of months ago for my Newport. He build txsm's for every genre from restoration projects to the top Mopar drag racers in the country. He builds a lot of txsm's that go to Germany, Finland, Israel, etc.

Well I bit the bullet and ordered a rebuilt 727 from Keith. A pleasure to deal with and got everything on time as promised.
I had it delivered to a friend's shop then I picked it up last week. It sure fit nicely in the trunk!
Keith said his catalog listed a TC with weights, however mine doesn't have any weights on it. Anyways, a new TC should arrive tomorrow.
I've been studying the shop manual and putting a list together, hopefully throw this sucker in the car within the next month...

I have one of these in my '69 NY. I love it. The shifts are firmer, but not harsh. Just as advertised. The weights on the converter, by the way, might be for helping balance the motor. I have heard that since 440's are internally balanced, using a torque converter from a motor that is externally balanced (such as a 400) should be avoided (I trust someone will correct me if I've got this wrong). My guess is that externally balanced motors use weighted converters.

Pat Blais Transmission,...he's been doing it for MoPar 727's for 35+ years.

...and roughly 8 months later, the weekend has finally been set aside! Got the tranny, TC, a new starter, new U joints, seals, O-rings, rags, pans, blankets, containers, and tools packed in the trunk (still with lots of room leftover, lol). Driving 100 miles east to the in-laws' ranch to do the job (since we live in a beehive and wrenching is frowned upon here). Should be fun.
