I have an 04 new body style f150, 4x4, 5.4. Where can I find what tranny I have? I pull a trailer a lot and want to help out my clutches all I can with a mechanical shift kit etc and not just bump up the line pressure. I heard that doesn't necessarily help out the situation. Any help would be nice. Also any advice to help out the tyranny would be sweet too, it operates fine with no slipping or anything, but with 107k on the ticker I just want to help prevent anything bad from happening.

 

You should have 4r75e, but check the sticker on the driver door for a 'Q' in trans code dight. It should have a TR above it.

 

You have a 4R75W with the 5.4L. I just had my trans rebuilt and they installed a transgo shift kit. Keep in mind the computer controlls the shifting in these trans when they are in automatic mode and that will affect your shift kit unless you have a tuner to compinsate for it.

 

I have a gryphon, and had a transgo in my tbird and could chirp the tires while shifting in that big heavy automatic

 

I just checked my tag, under TR it is a B. So is that a not normal tranny in my FX4? What upgrades would be good for my tranny?

 

Yup, 4r75e, just called Ford garage. Now what can I do to beef it up a little?

 

nope 4r75w. 4r75e came out in 06. trust me.

 

I swear, I gave them my vin and she repeated to me twice what it was.

 

The "Q" code is only used on 2006+. "B" code is either a 4R75W or 4R75E in a 2004 or 2005.

 

So what's the difference in the 4r75w and the 4r75e?

 

The 4R75E has a turbine shaft speed sensor. You do not have that as Gotts said.

 

planning on doing a fluid and filter change - is the filter the same on these, or diff. - whats the part #...
05 -5.4
also planning a plug change - holdingg my breath:o
independent shop say's he's done about a dozen of these and has not broken any yet,
it has 112,000 and i do not know if prev. owner ever changed them - i made it clear i was not paying any extra for broken plugs

 

Looks to me like all the 4R70/4R75 transmissions use the same filter.

 

for the trucks yes. In 96 all 4r70s got a deeper pan and a revised filter. The pan has that hump in the bottom where it sucks from. The early pans were flat and would lose suction around corners especially when cold.
