Hi Scotty I have a 2015 Subaru legacy 2.5I with the cvt tranny in it and has 156,000 miles in it and recently I replaced the axel in the car and lost a lil diff fluid doing so, so I wanted to just go ahead and replace the front diff fluid. Bought all the oil drained the old and in the process of filling the front diff back up I accidently put less than a quart more than half a quart of gear oil into the cvt tranny. I caught the mistake pretty quick and knew what I had done and did not start the car and pump any of the gear oil through the tranny!! Everything I have read says the port I put the gear oil into goes directly into the tranny pump it is on the left/driver side of the tranny right above and slightly to the right of the axel where it goes into the diff!! What do you suggest I do to fix the mess up?? Can I take the tranny cooler lines off the tranny and flush the fluid out that way?? If the gear oil went directly into the pump like what I’m reading would it fist go to the cooler then the tranny or the tranny then the cooler? I replaced the tranny in this car at 100k myself I’m pretty mechanically inclined but these newer cars and trannys scare me and I don’t want to be putting another tranny in this car again!! Any help would be so greatly appriacted!
Easy (and common) mistake to make. Not a real great design on placement of the fill plugs. But anyway...
Subaru CVTs are not DIY-friendly, especially for this kind of thing. I’m extremely impressed you swapped out the transmission assembly yourself. But even though you’re pretty advanced, I’d have it towed to a transmission shop that has experience with Subaru CVTs, have them open it up and thoroughly clean out the gear oil. If it isn’t done correctly, the transmission will never be quite right.
sorry to hear about it.
Drain it, or Suck it out with a fluid pump
You can’t suck it out that was the first thing I tried and I can’t drain it from where it went into the tranny without pumping it all through the transmission. Everything I have read and been told they all say it went straight into the tranny pump. It is a service port to prime the pump to avoid a dry start I guess if the tranny was new or rebuilt and the tranny was dry and completly empty the way I understand from what the dealer told me about it!! Of course they won’t tell you how to fix it they want the car brought in so they can charge me 1500$ for something I can do myself if I could figure out what’s the best way to go about getting it out!
Why can’t you put a long tube through the port you filled it by?
