Hey guys hope it’s okay to post this here. I have a 2007 Nissan Frontier LE V6 4x4. I want to do a drain and fill of my ATF. I had the fluid changed once at about 40,000 miles do to a recall on it. Than after around 90,000 my u joint needed to be replaced. I had broke my hand so I had to have a shop replace it. The tech said they had to drain the transmission so I’m assuming it was changed. Now I want to drain and fill it again as it’s due. I’m a big fan of Amsoil Oil and was going to use their ATF fluid for the fill. However I’m hearing people say that after 120,000 miles you shouldn’t change the ATF. It could cause problems such as slipping. My truck runs great and I have no problems with it at all. I want to change the ATF to help save the transmission not kill it. I’m hoping someone here might be able to help me decide if it’s worth doing or should I just leave it be. Thank you all for your help. Anything I should look for to help make the decision? Now it would only be a drain and fill. I wouldn’t be doing a flush as I know that could be bad. Any advice?
