I am trying to identify a Packard 3 speed trans with a Borg Warner R11 overdrive that was behind a 392 Hemi that I purchased. Any info would be appreciated. Main case casting 412234 Center overdrive casting R11-8B Tail housing R11-1D Looks like the top loading shifter forks have been modified. Possibly from an earlier trans? The overdrive solenoid id missing an the hole capped. Governor is missing and hole is plugged. Overdrive lever has heavy wire holding it forward locking it out? Missing is the slip yoke which I am trying to locate. It is 16 spline and the output shaft has a diameter of 1 3/8" and a barrel OD of aprox 1.710 Anyone have any thoughts on what I have here and where to find a slip yoke?
Pulling the OD cable out locked out the planetary gear set (overdrive). It looks like that is what they have done.
Cane shift is likely from an early non-OD trans. That can be done, the side shift gig bolts on top. My parts book stops at 41, that number for the case is probably postwar. R11 was more Clipper than earlier. You could try www.packardinfo.com and snoop around but the site is a little clunky. Some good info and water cooler talk on the AACA forum packard pages too. Edit: I have this one still, you can see how the column shift bolts on top. I'd take less (hint-hint)... https://www.jalopyjournal.com/forum/threads/48-54-packard-o-d-trans.1265100/
The R-11 was strtonger than the R-10, so that would be a plus. Solenoids and governors can be found on the web. I think Van Pelts has new solenoids. They are manufactured in 6 and 12 volt vareity. Not hard to wire up. I used modern relay's and switches vs the factory hardware which would need to be mounted in specfic locations. A cable is needed to engage the level which is locked open on your unit. Also easy to find.
Any ideas what year these components are? Particularly the tail housing that takes a slip yoke which I don't have.
Just stopped by Fast Shafts in Des Moines, Iowa and they have the slip yoke in stock. I am doing an R10 so would need to verify that they are the same spline. If you call them with the dimensions to verify, I'm pretty sure he will tell you if it will work.
This link is to the original BW overdrive manual. R-10 and R-11, lists Packard as one of the applications. I’d give it a really good going over, for no other reason than the missing gov and solenoid, before I installed it. They’re a great unit when wired and working properly. But if it’s marginal you don’t want to lunch it. Often they’ll run in direct, but not in o/d, so look first. Van Pelt Sales has a lot of those parts. http://www.oldwillysforum.com/forum/TechData/BWOverdriveManual.pdf
This R11-1D tail housing does not look like any Packard transmission I can find. It looks more like a Ford type R11. Can anyone ID the R11-1D casting number on the tail?
you got the hard part , the top shifter 37-39 only , i have a down load showing the mods to put on the later trans just the forks , , you have exactly the setup i want to run behind my flatty , keep an eye on ebay seems to be a lot of Packard trans parts there , and reasonably priced seems Packard's are now limited or parade use cars so there's not much of a calling for these parts ,, there are manuals for the overdrive on ebay as well , may help , I've read somewhere that because of the planetary in the over drive ,backing when its engaged can damage it , somebody correct me if I'm wrong , there are packard drive yokes on ebay as well ,, keep up the posts on this im all in fabricator john miss you dad
My Clipper had O/D, no worries backing up. It worked as a normal trans. If you went too fast in 2nd it would engage O/D on the 2-3 shift, and if you were deft enough with the gas pedal and clutch you could O/D 2nd, go to straight 3, then a light lift for final O/D. Car was fast for 47 technology.
That ****** was made by Packard '37-'54 and was hell-for-stout, big I8 and a big, heavy car. The early versions had a Borg-Warner R9 and the better R11 overdrive came along mid-way. The overdrive was always an option and about half of the production was straight 3-speed. jack vines
Thank you to all who have responded. I have learned a lot about these transmissions. I would still like to know if anyone has the R11- codes? This Borg Warner tail housing R11-1D does not look like any other Packard trans photos I have found.
If overdrive is engaged, meaning that it is actually in overdrive, it will back up just fine. However, if everything is working correctly, it shouldn't be in overdrive when the vehicle is stopped. The potential problem is backing up if the overdrive is not engaged but the overdrive cable is pushed in. That's because below the overdrive cut in speed, you are driving through a one-way clutch meaning it simply won't move in reverse. However, on overdrive transmissions, the shifter mechanism is designed to push the sun gear into the planet carrier when you select reverse (this is the same thing that happens if you pull out the overdrive cable). This locks out the overdrive and you are not driving through the one-way clutch so reverse works. The internal mechanism is spring loaded so that when you take it out of reverse, the sun gear moves back into the position to allow overdrive to work.
Jaracer, i stand corrected,, Indianmark i looked for a while on codes R11-1D ,, r11 obviously is the o/d model and next number being 1d was identified as the transmission code ,, maybe just to identify the housing application ,, this was all i was able to find thus far .... as usual i could be wrong found a free manual download http://www.oldwillysforum.com/forum/TechData/BWOverdriveManual.pdf fabricator john miss you dad
OMG some have is SO wrong, all manuals say NEVER back up with the OD engaged doing so will destroy the overdrive...BUY with a stock complete B&W T85/86 stock units there was a safety function where shifting into reverse IT locked the overdrive out so you can back up. ON the other hand you should also NEVER try to take off in overdrive, and this can happen with people who override the governor or hard wire a switch to switch in and out of OD, and leave it in OD and take off in first and OD...good by OD.
Also Looking high and low for a manual for the RARE R11 over drives. Every manual utube video ONLY covers the R10s I was working on a R11 and there are more differences that just a extra planetary gear, as in C clips instead or the U Clips the R10s use. Rich
The BW O.D with R11 in a 66 F100 I bought would jump out of second gear The rear rearing was worn and you could seperate the input from the output shaft with a screw driver The steel syncro teeth on 2nd gear were worn down The trans can leak out of the rear part and starve the rear bearing of lube The main case can still have lube I always put the trans in reverse with parking brake as well, would roll away in any other gear I read you pull the OD cable out and it would not roll would did not have mine hooked up Ricky.
That was the only safe way to park, putting it is reverse lock the OD up and it would not roll. Are you going to repair/rebuild that transmission?? Rich
Just ***embled 2 r10 ODs The reverse is locked out when the solinoid in engaged Pushes the sun gear out of the blocking ring if the cable is engaged but the solinoid isn’t.
