im new to this forum so bear with me. im a current student at UTI getting my masters in automotive technology, ive passed my manual trans class with flying colors. im a car guy so trust me when i say i know how to work on cars, especially nissans.
my 350z has 51k on it so i decided to change the tranny oil. its a 6spd manual. everything went smooth, put in 3.5 quarts like manufacturer specs, didnt overfill, didnt under fill, everything was normal.
i let my engine warm up every time when i start it like i should, and it shifts fine...until i get onto an on-ramp for the freeway. in fourth gear around 50mph, i hear this crazy loud high pitch whine from my tranny, sounds like underneath my e-brake, in 4th, 5th, and 6th gear its very loud, unless i let off the throttle, and it goes away, push on the throttle a lil bit and it starts again. after about 45 sec to 1 min it goes away.
calls for 75w-80 spec, but i couldnt find it in the store, so i bought 75w-90. of all the brands, they only had 75w-90, so i was like what the hell, why not.
is that the problem???? help please! i dont want to kill my tranny!
