98 ES 300, 80 k. Now that the overnight temp is 40 - 50, the car shifts rough (it's kind of lurching forward) in the morning maybe just once when the car shifts from either 2nd to third or from third to forth. Once the engine is warmed up, then there is no problem. Is this normal or something serious forthcoming?
The dealer chnaged the transmission fluid at 65k. My other mechanic says the transmission fluid is dark as if no change of fluid occured and he recommended a transmission flush for $200. The dealer told me that only 4 to 5 quarts of fluid is being replaced when they chang the fluid. Do I need a flush?
Thanks.
