I have a 2005 Toyota Camry with 44,000 miles. I recently had the transmission fluid changed at my mechanic, and soon thereafter a problem developed. When the car is slowly coming to a stop, and the car is going under 10mph, the car downshifts gears twice before it comes to a stop with a noticeable “clunk” sound. It accelerates fine, but I’m concerned I may be damaging the transmission. I took the car back to the mechanic thinking they may have short-filled the transmission or something. They connected the car to their computer system and can find nothing wrong. A trip to my Toyota dealer yielded the same results, no fault found. The mechanic drained all the fluids again and, under Toyotas advice re-set a computer in the car causing the car to 're-learn" the proper time to downshift. Toyota told us that this “re-learn” could take up to 500 miles to take effect. 500 miles later, the problem remains. Wondering if anyone out there may have an idea or two to share on this? ---

Did your mechanic “Change” the fluid or “Flush” the fluid??? transman ---

Yes, this would be my major concern. Are you SURE that the mechanic used the correct type of fluid for a Toyota? If he is one of those mechanics who uses Dexron for all transmissions and adds a can of some kind of addtive to “make it into Toyota-approved fluid”, that could be the source of the problem. ---

Thanks for your reply. The individual I need to speak with was out today. I will followup. ---

My receipt indicated “Flush Transmission including cooler lines, valve body and torque converter” 100% fluid change. Several replies to me have indicated that they may have not used ATF as a replacement. I did get one reply asking if they actually dropped the pan and changed the filter, which I think they probably did not do. Are you aware that possibly Toyota requires a specfic type of Toyota fluid? ---

Thanks for the lead. My receipt indicates they used a transmission fill kit Model VV 094. I’ll look into this. The receipt shows they " flushed transmission including transmission cooler, cooler lines, valve body and torque converter". Are you aware if Toyota specifies their fluid for this kind of work? I had two replies that asked if they dropped the pan and actually cleaned or replaced the filter, which I do not think has occurred. They said that sometimes during a tranny flush things get lodged in the filter. Any help is very much appreciated.
