So I've been having random 3rd gear problems where it will grind or kick back. Every time i take it to acura, they can never duplicate the problem which means that there's nothing wrong with it. After reading threads after threads i decided to try out the GMC fiction modified tranny fluid which seems to work well for others. I always bought the CT shortshifter, Corsport bushings and cable bushings. I am also thinking about buying a skunk2 knob for a heavier handle. Do you guys recommend any other ones? Should i stay away from the new fluid?

 

BTW, i have a 2007 TL-S

 

If you have warranty i would bring it back to the dealer. ANd if you dont i would still bring it back to the dealer i had my 3rd gear grind fix at no cost from acura they replaced the syncros. And also the GMC fiction modified tranny fluid will help but the other stuff like shortshifter and heaver knob will not help the grinding problems.

 

GM syncromesh modified fluid fixed my 3rd gear problems,
