BUT (yes, big BUT) the oil may have leaked onto the brake pads.  If so you need to do a rear axle brake job.
Well shoot, I assumed the oil around the right rear wheel was from the seal. But it looked kinda light, must be transmission fluid. Makes more sense as the oil is on the backside of the inner wheel.Those brake pads were put on in Indianapolis this summer, bummer. The fun never ends.

Any good truck repair shop can do the wheel seal, not motorhome specific.
Problem is all the big truck repair shops around here work on big trucks exclusively. Gotta keep the oil field trucks running.

Oil on the backside of the inner wheel is indicative of a leaking axle seal. If the brake pads got some oil on them, they may not need to be replaced. I had my curb side seal replaced at Colton Truck Terminal, and though the pads had oil on them, they cleaned up fine with brake clean. Believe me, if they thought the pads were ruined, they would have been all too happy to sell me a new set! by the way, my pads are original to the coach and at last inspection, they were still at 75% to 80% at around a 160K miles. A testament to the effectiveness of the Allison retarder and of the beefy nature of these air disc brakes.

Road,  as a quick fix to stop  so e of the leaking hose, get a short piece of hose that has an inside diameter the same size as the outside diameter of bad one and cut thru one side of piece. Place this short one over bad area and put a bunch of hose clamps along it to secure it to the leaking hose. I did this with a bad rad hose going to filter and it lasted over 3 months till I got home to replace it with silicone one. I realise the pressures are different but it will work if not a bad leak.

John the leak is at the connection with the transmission. If it's not raining tomorrow I'm going to see if I can tighten up the connection. I just took a quick look between showers this afternoon.

Very easy to tell by smell whether this is ATF or gear oil.

OK confirmed two separate problems, just my luck. I have a transmission fluid leak AND a right rear wheel seal that is leak. The rear wheel seal leak was confirmed by color and odor, like Brett inferred kinda easy to tell the difference by smelling.

I can't tighten the fitting where the transmission fluid leak is, so I'm going to have to have a hydraulic shop take care of that. Going to try to make an appointment in Carlsbad to have the rear wheel seal leak fixed. Gotta find some transynd first however.

Glad to hear not a REAL big $$$$ thing but still a major PITA. Good luck on getting things resolved.

Roland,

Tell us your route and perhaps we can locate a dealer who handles Allison Transynd.

I actually bought my Transynd from the Allison distributor/repair shop -

Amazon does not carry - a quick Google search turned up this on-lne source - no idea RE price/shipping costs

If you are just topping off, you can buy it by the gallon.

But, if changing fluid, the 5 gallon pail is less/gallon.  And, if changing, be sure to use genuine Allison filter kit.

Latest update. I had the right rear wheel seal replaced yesterday by an outfit in Carlsbad NM. I will supply the same and recommendations after this issue is resolved. After three seal was replaced we drove a couple hundred miles and stopped in a rest area on I 10 thirty miles east of Deming NM. Went outside to check stuff out and found a puddle of 90 weight oil on the ground. Now waiting to see how the outfit that did the repairs handles situation. Leaking worse now then before it was fixed.
You can't make this stuff up.

I wonder if they are trying use new style seal, and the old style ware sleeve is still on the spindle. Take a look at Barry's post on page 2 in technical guestions ptoblems with front spindle.

It's the rear seal that is leaking not sure the front spindle is related. Thing is all that stuff was replaced this summer drums disks the whole nine yards on both sides. And Dickensons in Indianapolis got all their part numbers from Foretravel. In any case still sitting here waiting AND I'm not a good waiter.
