If the electronic calibration strategy has been used since 1998 and carried into the current model year, Protocol 1 will be used. Small revisions that don't affect compatibility - such as a change in suppliers - usually result in the suffix changing on the service part number to indicate the design change level. What can be confusing about these numbers is that a part designed for one year might actually be used for several years, or a part designed for one car line might be used on other lines as well. The transmission serial number is a production serial number and should not be confounded with the engine serial number, they are not the same. But again that's just a guess. Does anyone have insight into this issue? Example: tires, drive ratios, etc.
But both input shafts have the same number of splines of 10. It could also be along the front rail. Both are wheel assemblies, but they have very different applications. My sway bar link is the same as a 2008 F250's but nowhere from 2004-2008 in the F150 parts list is that used. In any case, I may have avoided the 2003. This is why sometimes the part inside the package will have a different suffix showing on it.
Edited March 30, 2007 by Mike Tracy Here's some additional info: Model: C6 Type: three speed non-electronic Years: '66-'90 F-series '78-'89 Bronco '91-'96 '97? These protocols are designed to provide worldwide standardization for vehicle calibration. Need help decoding what axle or transmission you have? Hello everyone, I'm new to Ford Trucks. Also, what's up with the spring code? Wow, thanks for checking that out for me, Socmeddir. I know F-trucks used C4's up till 82 or 83 but I don't think any of the big Broncos ever had one. In 2009, the Ford company decided to switch the Ford Escape to a 6 speed transmission, that was a mistake. If you own a Ford, the order of the various codes on your transmission tag depends on your vehicle's model.
It is also a unique number, and changes due to specific equipment options on a given vehicle. We didn't get it because we heard that sound, and found out that had to do with the transmission. However, it sometimes made finding the right part very, very time consuming. For comments and feedback please email. Not printed on label -------------------------------------------------------------------------------- Thank you Christina.
Engines: 300, 302, 351, 460 Fluid:? And sometimes, the date code can be stamped in the wrong order, as in the example shown above. Get under it and pull the Axle code off the metal tag on the differentials. Service part numbers are normally listed on the packaging the part comes in, whether it be a box, plastic bag, envelope, sleeve, tube, etc. Yeah, mine was an October of 03' build and there are parts on this thing that were on the 04-08, but also there are parts that seem to have mysteriously been put on with no mention as to their original application. Date codes are located in various areas, and are normally comprised of 3 or 4 digits. I'm not sure how to read that? Early Cobra's and 65 Shelby's used and all aluminum T-10 while a variety of all aluminum and part aluminum and full iron ended up used on 66 Shelby's. Refer to Protocol 2 below.
Protocol 1 Item Description 1 Model year model year in which calibration strategy was first introduced 2 Engine code 3 Engine revision level Protocol 2 Item Description 1 Model year model year in which calibration strategy was first introduced 2 Engine code 3 Transmission code 4 Emission standard designates the specific country emission standard 5 Design level design level assigned to the engine Protocol 3 Item Description 1 Model year model year in which calibration strategy was first introduced 2 Vehicle code 3 Transmission code 4 Unique calibration designates different hardware to similar vehicles. This includes 2 and 4 wheel drive. Also, what's up with the spring code? The unique identifier is a series of numbers and letters that are put in a specific sequence, and the location of the digit determines what that digit designates. If I need parts I always tell them it's an 05' just to avoid issues, then if it still isn't right I have to take it to them and have the part cross referenced. The easiest way to discern if a part is a factory original or service replacement part is to check the fourth digit of the part number.
Ford 4 speed Toploader Built Ford Tough. If the electronic calibration strategy has been used since 1999 and is carried into the current model year, Protocol 2 will be used. This list may not be comprehensive depending on the year make and model of your vehicle. I returned it to the dealer I purchased from and they did say there was a problem in the transfer case and replaced it. All content copyright Rennacs Limited, 2009.
They will not shut them down to go fetch a part. The Ford part number on the box shown at left is on the top line: B8A-9431-A. Identification of the Toploader is easy. Refer to Protocol 3 below. Housing 2 different casings available.
