I just did my 50K Transmission flush (had a local Lube Shop do it) I was driving my truck today and noticed that my truck kept shifting repeatedly at 70 MPH, I don't know if it was because of some headwind that my truck was struggling to keep up or what!! I really never noticed it before and now I'm a little nervous. It hasn't done it anymore but still worried me a little. Anybody have any ideas or comments? Maybe something like "you should know better than to have someone else change your fluids!"
The best place for this question i sup in the Super Duty forum. The V10 forum is for engine discussions (for the most part) only.
How's your fluid level?
Are you absolutely positive that you have the correct fluid in there?

Yes this would be the first 2 things I would look into, especially the correct fluid bit. I would be pretty suspect of having a "jiffy-lube" type shop change my tranny fluid. At minimum wage I always wonder how much concern those quick-lube guys have for my $30,000-$40,000+ (new) truck. You don't see many BMW's, Mercedes-type cars in those places. I don't even let them do my wife's 2.0 liter Zetec Contour's oil. As I change it myself I get a chance to look at the belts, the exhaust pipe(s), the hoses, etc. I know what's going on with all my rigs by taking 15 minutes of my time and changing my own oil and fluids. It's time for a tranny fluid change on the big rig and I'm even going to do that myself, I'll let you all know how much tranny fluid I end up wearing ! I think it takes what, 16 quarts ? I'm going to Mobil 1 synthetic trans fluid @$6 a quart ? Yowzers, that's only the major portion of a hun, plus the filter,,,,,gadzooks !!

Just to let everyone know, I did take it back to the shop and had them change it again. No problems this time. I watched them do it the first time and second time, right fluid, checked the levels replaced the filter...everything. I have no idea why it had problems the first time. I can tell you that I do my own maint whenever possible, sometimes do have the time, but you can bet I will make time from now on with a 30,000 dollar truck!!!
If they drained the convertor then it is very likley that thet did not put enought fluid back in. I have done this the trans slipped and jerked like crazy. Once you drove it then it filled the converter and all you should have had to do is add some more.
