hi guys, so i had gone yesterday to streets of willow with speed ventures in my stock 01 s2000 has 107,000 miles, on my last session of the day i noticed a loud clunk/cracking sound when i would brake really hard and floor it after. Felt like it was coming from under the car, not only that i started to notice on my way home the gears where getting some what difficult to engage. which lead me to thinking it might be a transmission problem. The gears go in normal when the car is still. and the clunk/cracking sound only happens when the car is jerked. could this be the effects of bad transmission mounts???
