syfer

thanks for replying. no its not an engine knock noise and i dont think its coming from the engine either. it has to do with the trans. it gives me no problems but i just want to be aware of what it might be so ill prepare for it if it ever grows into a problem thanks. the noise is not from the engine, that was my mistake putting it on writing that way, it stems from the trans. a trans mechanic drove it and told me my trans was in good condition. ITS GOOD TO NOTE THAT HE THOUGHT IT MIGHT BE MY TIMING BELT. IS THERE A WAY TO KNOW WHEN TIMING BELTS ARE READY TO GIVE WAY?

hi gs guys, first off i must sau that the gs 400 is one of the best cars in the market, i dont care what yr u have , just be proud u have it. now to the problem i have ---when i accelerate hard in my car, i hear this noise coming from the engine right before it pushes off, this happens in any gear whether i am in the manual mode or not. ill give a better description of the problem but it will only make sense to the people that have driven a stick car before. you know when you are (lets say in 4th gear in a stick vehicle ) and you slow to a low speed, when you try to accelerate without shifting down, there is a clutch noise that the car makes which continues till you attain the right speed---thats exactly what my car sounds like when i press down hard on the gas pedal. i spoke to a lexus worker and he claimed not to know what i meant. said i needed to bring the car in but thats money right there. its good to know that i heard a similar sound in a 745 i in front of me and was puzzled. please someone help for i have put in 800 dollars already into my gs in the last month. :(
