I need to change my transmission fluid on a CVT transmission that is sealed. I have looked up some videos, but I trust you since you helped me along the way with my right side of my truck that needed the CV joint, lower control arm, and the strut package replaced and you were there with me the entire time answering any questions I had and offering advice and videos. I just need a little help with the controlled variable transmission because it is sealed, and I haven't ever had one of these before and I'm a little confused with the instructions that the guy at the parts store gave me.

Hi Melissa,

Yep, here are the instructions on how to do the transmission service and what type of fluid is used which is important.

All T355 Manual Transaxles require the use of ATF+4 (Automatic Transmission Fluid).

This guide will help walk you through the process, then check out the drain and fill port and filter change below.
