13 Speed Splitter Valve Replacement

Hoping some one knows which air lines go where in a 13 speed shifter. It has two red and two black hoses, when I took the hoses off it was easy enough to remember. Red hoses went to the front, black to the back, one black hose was longer than the other and it went to the right where there are three fittings, the left side has one fitting and it had a red hose. Aft hours of frustration I still can't get them back on right. I get air coming from the center (not the exhaust port) of the shifter when in low range and it won't #### to low.

 

Go to eatons website.

 

I tried that, they tell you where each one goes but that means crawling under the truck to chase hoses. I guess I have to do that. I was hoping for a simple "this red goes here, this black goes here..". Oh well.

 

You should be able to figure wick one is the main supply and where it goes on the shifter. Once it's in place, the others you can get by trail and error with the manual as a guide. Read up on the logic of how it works, it'll make sense.

 

Your colors are not as recommended. If you start the engine air will start to leak out of one of them. That is S-supply, and goes to the right front. Red. The left front is P, the range line. With air built up and shifted for air to come out of P connect the remaining lines to it one at a time. The correct line will make the loud range shift when connected and removed. Black. Now in high range one of the other hoses should have air coming out of it. That connects to HL, the center connector on the right side. Green. Now when shifted in OD air should leak out the fitting on the right rear. Connect the last hose, SP-Blue, and everything should work.

 

That was a great explanation. Thanks you.

 

Good afternoon fellas I have a 2012 Freightliner Coronado with a 13-speed Eaton in it and all the sudden I've lost 5th gearr and 10th acts like it's in neutral there has been tarantula downpours so I'm not sure if it might be electrical or something else no grinding no vibration no nothing didn't have 4th and 9th a few times things like that but now it's just 5th and10th gear I was told it sounds like the splitter valve anybody have any clue?

 

Should be a new post but start with listing the model #. Look for a tag on the right rear of the transmission. Post the # or send a pic.
