Been chasing a vibration in my steering wheel when in gear and stopped. Goes away in park or neutral. Have replaced all mounts with OEM (big $$$), cleaned TB, MAF and IACV and even adjusted idle to make sure it is at high side of spec. Just read on another forum where this guy was having same problem for years and did all the stuff I did. Finally he added Lubeguard. After a few days vibration was gone. My car is 99 Toyota Avalon with 140k miles. I replaced DexIII with DexVI years ago when I could no longer get DexIII. I was happy with performance. Two years ago I got stuck in snow bank and worked trans pretty hard getting out. Not sure if vibration started then or not. My question is could a cabin vibration be caused by ATF (type or condition) with car stopped in gear? Thanks.
PS I have been doing ATF drain/fills every 15-20k miles since buying her new in Aug 99.
