when im cruising at 70 and above and lightly on the gas its fine then if i push the petal prolly 1/3 the way to the floor not causing the car to downshift it get a wobble in the steering wheel almost the the tranny is tourquing im fairly sure this only happens (or i only notice it) when in fourth gear! o yea the torque converter seems to lock and unlock well im need to rotate and balance tires not sure if that could cause doubtful because how it occurs i have replace the drivers side cv axle (which had a split boot) thinking it could possible clear it up ... no such luck... any ideas !

 

Trans Mount? You should get that looked at soon! You dont want to be messing around with trans issues bro.

 

Take it to the infiniti doctor . He will put some good old japan bandages on it for u

 

How much tread are on your tires? Do you have them aired up? When was the last time your alignment was done?

Id say start with alignment and tires and see if the issue goes away....you mention it happens at higher speeds, which sounds like one of the two that i mentioned.

 

i actually have that very same problem on my 97. torque converter wont lock up unless i ease on it very lightly! and i also have that annoying shake. from my experience and to my knowledge i believe its the tranny just going out. if you have fixed the problem info on wat it really was would be much appreciated!

 

had the smae issue when i got my i30
fixed it with a full fluid change and filter, I use RP max ATF now it cruses at 75/80 mph like a charm.
