Nah I haven't tried a transmission flush. I read somehere else on here that it is good. How do you go about it? LIke what product do you use, how much does the product cost and what is the process? And it's done about 155,000kms. Thanks ahh you car is still a baby :P hehehe....... Transmission Flush, you have to take it to Toyota. What they do is, they drain the old oil then fill it up with new oil (I think they also use a high pressure system to clean the inside), then drive it around for 5-10mins. After that they drain the oil once again, fill it up with new oil and done. This takes up to 1hr, costs $100. But it is worth every $$$$. Gives smoother transmission and hopefully in your case it will gain abit of power. also remember to clean the intake filter n intake inlet :) Ahh i c. Well i've had my trans fluid changed a couple of thousand kms ago so I might just change it again and see if it makes any difference. Thanks for the advice! Lataz
