I have noticed that everyone seems to really worry about getting the fill plug out of the manual transmission before changing the gear oil. Then you have to use a fluid pump to fill it. I have always just removed the shifter from inside the cab. It just takes about 5 minutes to take out. Im not sure if it is different for 4x4's but in mine you just remove the shift knob pop off the cup holder console and then the shifter console(they just pop out) then unbolt the shifter. After that you just pour the fluid in through the shifter opening. It takes a little slow pouring but definatley faster than laying under your truck with a pump. Any thoughts?

Still need to pull the fill plug so you can watch it and know when you have it full. The published amount is more of a good estimate than hitting the actual fill level.

And yes, I have been filling manual transmissions through the shifter for about 25 years now. Just be careful not to spill any on the inside, it stinks and is really hard to get out of the carpet.

I've never quite understood why it's supposedly difficult to remove the transmission fill bolt. I replaced my 6-Speed's transmission fluid and had no problem whatsoever with the full bolt or drain bolt. I used a torque wrench to tighten both and expect no problems with future changes.

There is just always the possibility that a bolt can be stuck. It happens. I just wanted to give the option to people who may run into that problem or would rather not pump the oil into the tranny. I hadn't seen anywhere else that someone had mentioned it

i'm pretty sure it's much more difficult when you're using slip joint pliers (snicker). i don't have a problem with this task.
