Sounds like the transmission isn't been making a great connection. My Explorer does a little of that, but I have 186xxx miles.
Do you know if they just did a filter and pan gasket or an actual flush?
IIRC, that car still may run OBD 1 electronics so if you do go to get it tested, make sure the auto parts store has a scanner for such.
I doubt that a throttle position sensor would cause the tranny to slip. I would check the level and condition of the fluid first and also
stick you head under the car and see if you see any leaks.(the fluid should be red-ish)
Only problem is we are not there. Did the RPMs go up for minutes or milliseconds. Did it ever go back into gear. Did it drop down a gear then slam back into the higher gear. Does it happen all the time. Every day you drive the car. Does it happen when its cold or more when its hot.The part with "I didn't accelerate" sounds like tranny slipping to me. If the tranny was not slipping and the motor started to rev up, then he would have accelerated.
If you are cursing along at 40mph and have you foot steady on the gas and put the car into neutral, the rpm will go up quite a bit from losing the load.
IF his description is good, that is a slipping transmission.
Kinda funny(not you op) but I am on my 3rd tranny for just this week at work. That and I am (and still will be) waiting on my motor to come in from Japan for this lady's GS460......if she would have just payed attention to the gauges she would have saved $$$$$.
Atleast your explorer backs up //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gifSounds like the transmission isn't been making a great connection. My Explorer does a little of that, but I have 186xxx miles.
