I stand corrected. Thanks for clarifying that. I've never dealt with any Lightnings. There's always exceptions. The '02 F250 5.4L V8 Superduty, we have at work, is 2wd and has the deep pan.

 

I just experienced what I'd consider shutter while sitting at a light. I let off the brake to pull forward a few feet and it was jerking forward. I stopped, then let off the brake again and it was fine. Waited a few seconds and tried again and couldn't reproduce it. Then pulling away from a light a few blocks away it did it again. Pulled over and checked fluid and the level is fine.

Any ideas?

 

Trans temp was at 150 and chip was in 60 tow (no load). Just did a hard accel and didn't feel anything abnormal.

 

Not-so-sure that the re-used filter is such a good idea.

Also, did you pay careful attention to the orange o-ring where the filter mates to the trans?

Just thinking out loud.....

Yes, I inspected the oring carefully. It looked and felt fine. That was the first thought in my head, oring sucking air. Hasn't done it since, been in stop and go red lights for the past 30 minutes.

I agree, reusing the filter was probably not the best decision I've ever made.

 

Reps sent for video and pics....

 

7.3's only, like Mark posted.

4R100's are used in the V10's too.

Aint there always something that muddies the water?

Wasn't able to reproduce the shutter all day. Maybe it's just my mind. Who knows...

 

Jeff, you are free to run the radio she'll be fine.
I try to remember to run mine a little every day.

When I dropped my pan and changed filter there was no way that the orange o ring was falling out. Took some work to change it.

 

Hey Jeff, ill be back down there like the second week of march, so if you wanted I can hook AE up and maybe see whats going on with ur truck.

 

Sounds good rob. I'll be in live oak March 20-25, so if you're here any weekend other than that one, we'll set it up. I think a slip test might be in order.

 

And the 5.4L, too, and some F-150s and Expedition/Navigators. All second generation Lightnings were 4R100s, too.

Only a trans from a 7.3L will bolt to a 7.3L.

 

Great write up Jeff and Mark. Thanks for doing it.

 

Great write up and photos. I have completed the trans fluid exchange as well following Mark's write up. The only thing I added was oil analysis from Blackstone. When I first pulled the fluid it was very very dark but didn't smell burnt. I first changed the oil at 187,900 miles back in 08. I bought the truck in 05 @ 153,000 and didn't know the history. I just made the assumption that I had 30,000 miles on the fluid. The report back wasn't bad but wasn't good either (IMO) Blackstone stated iron, read at cautionary levels (258ppm) and recommended a 15,000 mile oil change. After 9,900 miles I pulled a sample and again the iron was high(205ppm) but down from the last sample. They recommended another change, which I did and a sample after 10,000 miles. At 11,500 miles I completed another full service and sent in a sample and the report back was alot better. Iron was down below the universal average of 156ppm to 56PPM. I then ran for 20,500 miles (01/2010) on this fluid service and the report back showed typical wear levels. Viscosity normal and no trace of moisture or contaminants. Insolubles are at a trace. Iron at 72ppm up from the last sample and all levels are down under the universal averages. Recommendation: 30,000 miles for the next change. I plan to change out the fluid next month (close to 30,000miles) and send in a sample. I have 266,000 miles on this 4R100 transmission with no repairs made. I haul a gooseneck horse trailer and haul a 9" cabover camper. I use the Ford filter and Valvoline Merc V. I think adding oil analysis as part of the maintenance process a small price to pay for getting the most out of these transmissions.....

Thanks for the addition. I was too scared to do an analysis on this change. Probably not the next change either (planning on a 10k second flush) but after that I'll prolly send in trans and engine oil for some info.
