Went to Tucson today with my mom for a Dr Appt. Had earlier this past weekend responded to an ad for a SB 727. Guy claims it was yanked out of a 74 Road Runner 360 car.

I met up with the guy and followed him about 30 miles to his house out in the middle of nowhere.There was the tranny,along with what looked like a 73 or 74 RR that looks like it had exploded,parts everywhere.

The guy told me on the phone that the converter came with the tranny,but this mustve been a different guy I was talking to now.There was no converter and the guy claims the tranny had been sitting outside for 3 months but was functional when they pulled it.


So what can anyone tell me from the numbers where the pan seals up?

Look at the crossmember...Sure dont look like a Car crossmember to me.

Whats with the drilled hole and 3 lines in the bellhousing,is that a rebuilders signature or
what?

This is a 727...Correct?

So last question,asking price was $100,I drove away with it in my trunk for $75. Good deal or Bad deal?

The crossmember. This is a Van or Truck crossmember...Correct?

So whats with this "signature" what does it mean?

The cross member is out of a B series van and the hole is for setting timming in the vans.

Here's the link from the archives.

IIRC all the van/truck trans had a 4 gear planetary.

you didn't show enough to prove it is a 727 at least for me. Pan area.

The hole was mentioned in a post about transmissions and I recall it is from an RV. So it would be a BB then?

Cool Wild Bill,Thanks for the numbers. Im having trouble locating the one on my tranny in the ones you provided.

I have found the following in that list:

3736139..........318/360......727..........truck, medium


*3736145..........318/360......727..........truck, short



*3736147..........318/360......727..........truck, long(heavy duty)


So wheres my number? Is it true what the seller states that my Tranny is a 1974?

So what does the whole 4 gear planetary mean?

Yes, 727 from a van. For 75 dollars you got a very good deal. A engine 727s are harder to come by than Big Block ones around here.

Production date - Aug 9, 1973
5359th made that day.
P/N 3736141
PK - Kokomo

A more complete list of numbers

Standard car trans have a 3 gear planetary. Some, Myself included, beleive the 4 pinion planatary is stronger then the 3.


I have a van trans in my race car now.

Found it,

74-5 318-360 B 100, 200, 300 vans

From Wild Bill's list.

Thanks for all the help guys

Will all the linkages and kickdown stuff bolt right up to this,or am I gonna have to tweak stuff here and there?

Is your car a column shift or console/floor.

Column shifts require the tabs on the bell housing (drives side) floor shift cars require the tabs that are on the tail shaft housing just below the speedo gear hole.

My car is a column shift car
