Tranny maintenance

The wind finally died down today so I did the tranny fluid change on the motorhome.  I first marked a 5 gallon bucket at the 1 gallon, 2 gallon, 2 gallon + 1 quart, 2 gallon + 2 quart, 2 gallon + 3 quart, and 3 gallon mark.  I was told I would only get about 3 gallons out on a refill.  I purchased 3 gallons of PB Autrans Syn 295 at about $57 a gallon (ouch!).  Finally I slid the bucket under the tranny and pulled the plug.  1 gallon, 2 gallons, 3 gallons (oh no!).  Imagine my anxiety when it went past the 3 gallon mark with no sign of slowing down.  After pulling the pan and draining the screw on filter I measured 3 gallons 3 quarts and 3 cups.  Off to the store I went for another gallon.

 

 

Well all went fine.  There was absolutely no metal in the bottom of the pan.  Some fuzz on the magnet in the pan and filter, that’s  normal.  I was thinking I should replace the main filter since it was right there after pulling the pan but didn’t want to run back to the store.  Would probably have to order one anyway.  Also I figured since the fluid was so clean and the main filter change is only recommended during a rebuild, I didn’t worry much about it.  I placed a tarp under the motorhome just in case but didn’t spill a drop.

Torque specs on the pan bolts are 18-21.  I torqued them to 18.  The drain bolt is 22-30.  I torqued it to 25 which sure seemed tight.  Next I started it up and ran through the gears leaving it in drive and reverse for about 2 minutes each then put it in park and checked the level.  Lastly I shut it down and checked for leaks, none found.  Glad that’s done.  Since I used synthetic this time, the next change isn’t for another 100,000 miles.  In other words…never again.
