(some manual transmissions use ATF, some use gear oil.

Their is no modern manual TRANNY or for that matter any T5 that uses Gear oil.


Their is a whole lot of Bad info on this post. And i think you should ignore most of it. Other than follow the manufacturers recommendation on intervils and Fluid type. Peace Tom

I am going to do this, sometime this week and will post an update.

Who makes up this Garbage. So lets see the people that design the transmission does not know about synthetic motor oils and chooses to use ATF. Fascinating how people start these WIVES TALES. This post is dangerous and costly for some that do not know what they are doing. I would suggest having your tranny serviced by a professional other than people that are sketchy about it or believe these posts as gospel. I cant believe what i am reading here. I in my best day cant make this garbage up.

By the way modern trannys with out dip sticks have a set refill procedure and some need a scan tool to accomplish this. So i would suggest not to follow this post unless you are a professional. You just might be replacing you tranny that was working before you tried to service it. Peace Tom

Because it interferes with the lock up clutches in the converter. And it throws the converter out of balance. Some trannys have drain plugs on the converters and they can be removed but you cant remove them to many times. You will strip them out quite easily. It is not a communist plot. That is why we have a tranny flushing machine. Anyone that drills and taps a converter is playing with fire. Peace Tom
