Mopar transmission ID help please

I have a chance to get a original 40k 318 motor and trans combo out of a 1969 dodge motorhome, but the trans has what appears to be an e-brake set up on the rear of the tailshaft (a drum?) . What kind of auto trans is this and is it a good one to use in a engine trans swap? Sorry, no pics, I'm on the work computer and it won't let me do it. Bud

 

It's a A727. Bulletproof trans. I'm pretty sure that if you unbolt the E Brake, you can bolt on any pre '65 trunion style driveshaft.

 

with an E brake in a commercial ch***is it's like the white guys says a 727

 

If its a 69 transmission, wouldn't it accept a later model driveshaft?

 

If it has a trunion style flange, you can find a later model 727 out of mid 70's vans that had a bolt-on U-joint yoke that should swap on. Try a ****** shop for these.
There is also a "conversion" joint that'll bolt to the trunion and allows standard u-joints.

 

So where does the slip take place? I want to convert my 65 Barracuda 904.

 

In the driveline....like a 4wd.

 

In My opinion Keep that E brake on the back of the Transmission. What can it hurt. A 727 with a rebuilt Ebrake on the driveshaft. YEAH.......... 727 is the Best you could hope for.

 

thanks guys, I knew I could count on you. I will tell the lady it is SOLD.

 

I had an Iveco with a 727. Long story, but the case need replacement. Seems the motorhome and large truck cases, esp. the tailshafts, are different. The bearing is larger, is a bearing, and the shaft is different as well. You may need a donor trans to swap to auto-style tailshaft.

If you were putting the truck trans in a street rod or truck you would have more clearance, I've done some swapping around with these transmissions, the parking brakes and drive shafts. Not all flanged Mopar drive shafts have the same size flange that fits the drum. From what I've been told in the past you would have to change the main shaft and tail housing to convert to a conventional trans, not easy or cheep! I would find another 727. If you decide to go ahead you can PM me and I'll give you any tips I can. David

 

Oh, I forgot to tell you, a friend of mine bought a low mileage 413 motor home engine and trans wanting to put it into a Dodge Dart, not only is the trans a problem, but the small and big block Truck/Motor home engines have a lot of differences that will be a h***le to convert for use in a car, just to mention a few: water pump, timing/water pump housing, possible gear to gear instead of gears and chain, intake, and especially on the big blocks-heads and non-interchangable exhaust manifolds. I also have one of each motor home small and big blocks. Good luck!

 

All you should need is the output shaft and tail housing. They shouldn't be too hard to come by.

You do need to do a complete teardown of the transmission to install the output shaft though. Torqueflites are easy to tear apart and re***emble though so I wouldn't get too worried about it. You might have a couple of hours invested in doing this if it is your first attempt at it. Even less if you have experience.

 

Since I'm getting the driveshaft too, can't I just have one made to accept the front shaft?

 

If you're got the room in your driveshaft tunnel for the E brake, just use a four wheel drive style driveline with the slip yoke and spline in it and call it good. If Jag could do it in the XJ6, why can't you? (they also used a two piece driveline that utilized a carrier bearing and a really funky rear transmission mount, but that's not the issue here) Converting to rear disc brakes? The driveline E brake would mean you wouldn't need rotors with a drum brake inside or rear only calipers to have a parking brake.

Same goes for the front end accessory dress, if you have the room in whatever you plan on putting it into, why not?

 

This is what I got for $300.00 with 49k on the clock. no sludge in the engine and the oil is clean and fresh looking, the trans fluid looks like new. oddly enough, this 318 was built on 3/18/1968

 

Yes on the D/S, but as the others pointed out on most truck/motor home applications the slip yoke is on the second D/S just after the hangar bearing, you can take all of the shafts apart and make up your D/S similar to the one I posted before. Looks like you got a good buy, it just depends on what you put it in whether the truck parts I mentioned before will fit. Let us know later.

 

Wow,
I thought I have seen a lot of mopar water pumps, but that one truly is unique. The 1969 318 I have has the water pump pulley mount much lower.

 

apparently it has a unique timing cover that was made for certain motorhome uses. I got a stock timing cover and the water pump will be in the correct place. Anybody need to mount their water pump higher? I have just the part for you!!!
