Ok my transmission....grabs fine....goes into gear fine.....doesnt grind unless i have a crappy shift....buttttttt it has started to whine alittle you can barely hear it unless your listing for it due to my exhaust i think it would sound louder if i had stock exhaust.....it rattles some times when im in low rpms and its like i can here all the gears....but if i turn on my music loud and cant here any of the noise i would never think the trans is bad so do i have a problem and if sooo im thinking about rebulding it....are there any rebuild kits out there good but wont break me....and i have a shop that does all my stuff cheap how many labor hours do you think it would take to rebuild mine and can any one give me a estimate on the total cost of all this and any cheaper solutions

one month ago i drained it and put in redline mt90
