I did the rear differential breather today. Easy Mod. Went to check the Transfer case and transmission breathers to see where they are at and how high up on the truck they are. On my 04 Tacoma the transmission breather is not running up higher, its right on top of the transmission.
Here is the Differential breather that I put in behind the left rear tail light
Here is the transmission case breather on top of case up by shift
And the other breather on the transmission is also on top of the case. You cant see it because of the angle and how close it is to the floor board by the shifters
The breathers are just like the one on top of the Diff,except they are molded into the transmission case. Which means you have to attach the hose to the top piece after you remove the cap.
Here is the point of this post. The transmission on a 04 Tacoma Does not come from the factory with the breather raised up, at least not all of them? I will need to access the top of these cases from inside the cab buy pulling off the shifter boots and the cover to get at the top of the cases. There were a lot of posts that said these case breathers were already raised up. There are two breathers under the Hood probably going to Frt Diff and transfer case. But the ones I found on top of the transmission will need to be moved or water will come in thru them.
