Keep an eye weekly on that engine oil level until you figure out why it was low.
Its not uncommon for it to be down 1-2 quarts between oil changes but it could be a symptom of something else.

|Howard Avery||I changed the engine oil because the level was very low. Tranny fluid was full when I bought it.|

|Absolute||Just out of curiosity , what fluid did you put in there? Transmission I mean|

|Howard Avery||Okay thanks Mark. Maybe the oil change/trans shift thing is only a co inka dink, but it happened. Sorry, I have no way available to get the PCM data, so I guess time will tell if I actually have tranny issue or not. Thanks again.|

|Mark Kovalsky||No, engine oil doesn't affect the transmission shifts. An extended time in second gear may or may not be a problem. There really isn't enough information here to diagnose that. I'd need the pedal position that you are at (from a readout of the PCM data) and the vehicle speed it shifted at. Also, a time from when the PCM commanded the shift until the shift actually happened.|

|Howard Avery||Okay, update on my shifting issue. Like I mentioned originally, we just recently purchased the Excursion when we noticed the strange shift from second to third gear. Along with checking things out, I noticed the oil level was low and looked like it was way overdue for an oil change. So I changed the oil and surprisingly it seems as if the strange shift has gone away. The only thing I notice now is that it seems to stay in second longer than it should and that hard acceleration sometimes causes a hard shift. With lower acceleration the shift is normal. Even pulling my 8k pound camper the shifts are smooth. So I guess my question would be does the engine oil level affect the transmission in any way and is the extended time in second gear sound like a possible issue?|

|Absolute||Hahaha, yup, valve body, my typo. Oops. But yes, I totally believe that VALVE BODY made a massive difference in the longevity of my transmission. It also made massive improvments in shifting across the board with all my tunes. Towing included. I think it was around 200 bucks when I bought it, well worth the dollars. Wish I could afford the transmission he makes as well. Being in Canada, by the time I cover shipping and core return, exchange, duty etc etc, I'm looking at about 10k for it. Want it , just cant buck up that much right now. I'd prefer to do a standard conversion. Had an entire kit lined up, with everything I needed, procrastinated, and at 1500 for the whole works some one else scooped it up before I was done humming and hawing. Haven't seen one since. Any one have a tissue.|

|Mark Kovalsky||Valve body, not throttle body. Transmissions do not have throttle bodies.|

|Howard Avery||Thanks guys. Sorry I couldn't give a better description of the problem. Just one more question. Does engine oil level have anything to do with transmission performance? I was reading some of the earlier posts about transmissions and came up on one that mentioned that it did. Anyway, I did notice my oil level was low, so I changed the oil and seems like it's shifting much better? Crazy or what, lol?|

I probably have 50 000 miles on it since I exceeded 500hp, still holding together. lol

|Mark Kovalsky||I don't know what the problem is. I need more data. You need a tool that can tell what gear the PCM is commanding, and whether it is commanding the torque converter to lock or not.|

The stock 4R100 in my 2000 7.3 had a weird kind of shift when under full throttle for that gear.
Original 4R100 lasted 203k miles, I replaced it with an HD4R100, the odd 2-3 shift under power was gone, so someone figured out how to fix it in the HD version.

|Howard Avery||The fluid level is full, no odor and is red in color.|
