Hello dudes im new to the fourm just wanting to get an opinion from you guys. I got my 2012 nissan sentra (automatic) 2.0 at around 95k miles with no service history. My manual says that my car needs it every 30k.My question is since I have no idea when the last fluid swap was done would it be advisable to do it? I checked the quality of the fluid still looks redish in color i don't have any slips on the cvt. The only problem that really errks me and the reason i want to change the TF is the poor acceleration. I've done a full tune up in hopes that it would be the solution to the acceleration problem but not really. So official question i don't know the service of the vehicle should i go ahead and change the transmission fluid? Or would doing so mess up my tranmission?
