4R70W Video and Pictures

[Smokie]

I found this while searching for info on our transmission.
Complete video of disassembly and assembly, plus pictures of parts. I would recommend downloading and saving in your hard drive. A lot of companies charge money for videos like these.....enjoy.

I originally posted this a long time ago and original link is gone, courtesy of Magindat and the Sunshine State Marauders the above are current links to downloads of the 3 video files. I hope that these videos remain as useful today as they were 3 years ago. Javier.

Is the 4R70W that the '03 models have. The '04 has a 4R75W.

There are differences, but overall those 3 videos contain a wealth of valuable information that applies to more than one specific transmission. It can answer a lot of questions that our members have posed from time to time.

It can make even a novice well informed and have an understanding of what is inside that "mysterious" box right after the engine and before the drive shaft.

Javier - Thanks, great videos.

Thanks, now we know what the tailshaft is and how it is lubricated, separator plate, accumulator springs, O/D band. mechanical diode shaft, c-clip that likes to come off. It puts a face on some of these components.

The '04 has a 4R75W.

NOT all 2004 Marauders have the 4R75W.
You have to check the Door Label.

Code H or U is a 4R70W.
Only Code R is a 4R75W.

It seems there is a bit of overlap between model years in a lot of different areas. Here is a bit of information on the differences between the 4R70W and 4R75W.

Source Blue Oval Forum:

4R75W is an updated 4R70W.
4 is the number of forward gears.
R is Rear drive
75 is the torque capacity of the trans without the zero. Thus 750 ft lb on the input shaft.
W is for Wide ratio.
4R70W is one of the more reliable auto's, so the '75' should be also.


Source Ford.com:

The 2004 Marauder also gets a new 4R75W heavy-duty, four-speed automatic transmission for greater efficiency and low-end torque. Other refinements include the addition of needle bearings and Teflon seals to a new 11.25-inch high-stall-speed torque converter with a one-inch one-way clutch. The new transmission provides quicker upshifts and downshifts, and lets the driver “kick down” into first gear at a higher speed.


This is the most complete explanation I have been able to find in regards to the differences.
