A TRANS OVERHAUL possibility because of a cheap filter repl during a trans service is not an option in my book.

Re: New baby 1953 Merc
Ford's licensing deal with Borg Warner only lasted 5 years. Ford wasn't the only company to use BW designs before or after that time frame. The Cruise-O-Matic came about because Ford hired a previous engineer from BW.
A screen can be cleaned easily no mater what shape it is. Some do require special chemicals in an untrasonic bath but they are generally used in aircraft turbine engines. |

The actual ID letters/numbers were stenciled onto the left side of that oval plate with red paint in the rectangular silver box, but that's all gone now. It should look more like this poor example below... Last edited by dmsfrr; 06-25-2021 at 01:47 PM. |

Re: New baby 1953 Merc
OK ....
More bad news. The ID PLATE has been altered by a re-builder. That is a SERIAL NO and how they keep track of the trans they go through. Hopefully it is the OEM install and not an exchange. As for case measurement, there is a chart below that shows the case lengths. Follow it very carefully as to measurement.

Re: New baby 1953 Merc
Now that the clouds are dissipating ... ... awful fancy word ...
I owe you an apology. For some strange reason (CRS most likely), I have confused you with another member here, Dobie Gillis. You included a photo attachment in an earlier post and that car is absolutely beautiful. I hope MERCMAN FROM OZ reads this and blows the photo up so we can see more detail.

Re: New baby 1953 Merc
Well I do own a Merc but it's a '55, not a '53.

The main case only is measured. There is a small extension between the main case and extension housing that is not included in the measurement. Look at the ILL closely. If it is truly a small case, you know you have the correct period trans.

Re: New baby 1953 Merc
. I9-1872S2 . It's an air cooled Fordomatic that came in a '55 T-Bird I bought a while back.
Might be original to the car, or not, the engine wasn't. . Last edited by dmsfrr; 06-25-2021 at 07:35 PM. |

In the Hemmings article (https://www.hemmings.com/stories/art...c-transmission) it states: The Ford-O-Matic was manufactured in three different case sizes. It was initially offered in both small-case from 1951-'60 and medium-case from 1951-'68 (often referred to as the Merc-O-Matic); large-case versions were also used in 1958-'65 Lincolns. If the article is accurate, I am guessing I could have the "medium" case, since it is a Merc-O-Matic. I will jack the car up again tomorrow (with a jack stand in place) and remeasure just to be sure of my initial measurement. Any information on the IP-7000-N, that was only use in Mercury in 1953, per the parts manual. Was this a small case trans? Would there be any other tags or identification numbers, on or stamped on the case? Last edited by Merc Cruzer; 06-25-2021 at 08:24 PM. |

Re: New baby 1953 Merc
The HEMMINGS ARTICLE is inaccurate (as a lot of TECH ARTICLES are).
I too thought the mid-case was introduced early but the MPC states otherwise. You would need the years discussed AT WSM to actually nail it down. Look at the attached chart - There was no need for a stronger trans (IMO) until the 292 was introduced in 1955. Quote:
There may be CASTING ID CODES and/or CASTING DATE CODES. Anything you see with numbers record. MERC-O-MATIC 1951-1954 was a MERC DIV advertising description.

Re: New baby 1953 Merc
Mercury, Thunderbird, and Lincoln cars were the first ones to use the medium case Ford-O-Matic/Merc-O-Matic/Turbo Drive for 1955. They wanted heavier duty drive train for the Mercury & T-bird. Lincolns had larger engines so the application was called the Turbo Drive using the bell housing for the 341 initially followed by the 368. The large case transmission came on line in 1958 for larger displacement applications like the 430 MEL.
FoMoCo did use the GM Hydramatic for the 337 initially in 1949. I don't think they wanted to but they likely had plans to change before the big fire at the GM plant in Livonia back in 53. This set GM and other manufacturers that depended on the 4-speed Hydramatic back till they could crank back up at the old Willow Run B-24 plant. I'm sure this helped Ford develope a follow on transmission to avoid such things in the future. Rambler and Studebaker/Packard used similar design transmissions for some time as well but they differed a good bit from the ones Ford used since they had different engines and so on. The 1955 thru 57 T-birds show to use the medium case transmission. The early ones through 1957 were all single range units. Most Ford cars didn't get the medium case transmision till 1957. The T-bird is the exception. Last edited by rotorwrench; 06-26-2021 at 04:04 PM. |

Re: New baby 1953 Merc
More Info Below - incl 1951-53 FORD APP CHART
1P-7003-N used in both FORD and MERC. I am beginning to think those modified TRANS ID TAGS were used by AUTHORIZED FORD RE-MANUFACTURERS used during this and later periods.

Re: New baby 1953 Merc
The "X" frame, used on the convertibles makes it a bit difficult to get a thorough look at the trans. Project for the day is, to employ a mirror, and see what I can find, along with seeing how close to 9 7/8", the case of my trans is.
*********************** It definitely helps to walk in with a known measurement. Upon remeasuring, the case and only the case, is in deed 9 7/8", in length. The only other casting mark I found, with the aid of a lit mirror, was a raised "W 12", cast into the top of the case. Thanks for all your help. Now if I can find a picture of an original ID tag for these transmissions, I need something to compare to mine. Last edited by Merc Cruzer; 06-26-2021 at 10:44 AM. |
