There are times when I really would like to reach out and touch someone at Winnebago, GRR!
We bought a new Adventurer LT on July 3, 08 with the new Workhorse UFO gas pusher chassis. Aside from the normal and frustrating minor problems at delivery we were on our way in short order. After one return trip to the dealer for some service problems we set off for Duluth MN. On our way I discovered a transmission oil leak (oil all over the front of our Toad). Called our dealer and found we had to contact Workhorse for chassis service. (I wonder how Winnebago handles Michigan Lemon Law issues?) Called Workhorse and was referred to a truck service facility in Superior WI. Talked to the technician who worked on the problem. He claimed the oil pan gasket was leaking. I am a retired mechanic so I had a look but didn't see anything. Anyway, no disputes, just replaced the seal and on our way. 177 miles later in St Cloud MN the same problem showed up (oil all over the front of our Toad). Crawled under and checked the leak. Seemed to be lots of oil around the Shift Selector shaft. Called WH. We talked, and agreed it may be better to go to an Allison service shop. Nearest shop was in Virginia, north of Duluth. WH suggested I talk to Allison and I called their Tech Support (800 252 5283). Allison Tech support agree, go to Allison Service in Virginia MN. When I talk to the service tech he crawls underneath and comes back with Yup, seems like the Selector Shaft Seal. When the seal is removed we both agree there doesn't appear to be any problem with the seal but a new one is installed and we are soon underway. About 270 mile into our trip and I again find oil all over my Toad. By now I am no longer a happy camper. My clothes and hands are covered in black oil every time I unhook/hookup. Call Workhorse again. We discuss options and agree I can proceed to Stoney Creek ON.
Park it for the weekend. Talk to a mechanic I know, he says is the oil coming from the case vent? Oh Oh, why didn't I think of that? Crawl under, stretch my arm up and run my fingers around the vent. Lots of oil and dirt, Bingo!
Tuesday morning into the service bay at Detroit Diesel. Talk to the Tech. Tell him my probs and what has been done and what has been found. Yup, he says he will crawl under and check the vent. Back to me, yup oil from the vent. Asks me to open the back so he can get to the Dip Stick. He runs his fingers around the top of the tube and says there is a Vent Hole missing. Also says it is a common problem with Allison Transmissions. He drills the hole and I am out the door and on my way back to our campground. A few hours after we are settled in I call Workhorse and tell them what was found. Workhorse customer service claim to be taking notes. Thank me for the information.
Not long after, I receive a call from the Allison Service Shop in Virginia MN asking me if all is OK. I tell of my continuing problems. After that I call Allison Tech Support and ask if they are aware of the Dip Stick vent problem. Oh yes they say, we know all about it! All the OEMs were advised to vent the Dip Stick tube in 2 places. The OEMs are given a time limit to carry out the work, after that they are responsible for the cost. I call back to Virginia. Oh yes, we know about the vent problem!
By now I am back to my old "HATE WINNEBAGO" attitude.
Winnebago build the coach and should be aware of all recalls and engineering mods relating to the chassis they use. No one at Winnebago took the time to check engineering issues with the Workhorse chassis. No one at Workhorse bothered to follow through with engineering issues relating to the equipment used in the construction of the chassis. The selling dealer couldn't care less, they don't deal with chassis issues. I am out several days and many unpaid miles on my MH. No one pays me for my out of pocket expenses. As usual, the builders just shrug while the customer gets the shaft!
By the way, if you too own a new MH with the WH Gas Pusher arrangement you too may have the problem with a transmission oil leak. And OH YES, try putting oil into the filler tube! It takes a turkey baster with a thin hose attached to put oil into the transmission. And the best of luck to you too!

I too had oil all over my Toad on the first trip. I guess I was lucky as I took it to the local Workhorse repair facility and they found the problem right away. On mine it was just a loose connection on one of the transmission cooler lines. Some teflon tape (I presume) and tighen the fitting. 8,000 miles later and not a single drop of trans fluid has been lost.

Wow - how frustrating - I can feel your pain!

Line most airline accidents, it was caused by a series of multiple events: Allison didn't vent the case, Workhorse either didn't get the word about an unvented case, or didn't follow through if they knew, Winnie either didn't get the word about an unvented case, or didn't follow through if they knew.

I had an issue of slow retracting jacks that took two years to finally resolve. Out of desperation, I took a trip to HWH for the issue and it took the tech about five minutes to tell me "oh yeah - we had a bad batch of jacks where the inner seal was compressed too much which caused slow retraction" ... what!?!? Why in the #$&$%@!* didn't you tell somebody (or maybe they didn't track parts) you had a bad batch of jacks??

Welcome to the club Hopefully you are now done with major issues.

John - HWH is good about that. We bought a new coach in Feb. 04, went to West Coast in May 04 and in June on that trip one morning the jacks wouldn't retract. After several phone calls to HWH finally just had to retract them manually by releasing the valves and proceeded on for several days until we could schedule an appointment with a Winny dealer. Took Tech 5 minutes to determine the control board was fried. When he called for replacement, HWH told him that was a new model control board and the were having problems with it. Said he was surprised it lasted us 4 months. Why in the h___ didn't they contact all customers with this information. It could have saved us 4 days vacation time plus the cost of extra nights stay and overnight express on the new part. Guess its always cheaper to let the consumer find their problems but maybe they won't complain about it.

Beethovin - This stuff makes us nuts.... As far as you know is this vent-hole issue ONLY with the UFO gas pusher? Thanks for any info, 'cause I don't trust the companies to give it to me.

John . . . tell me more about the HWH slow jack issue. Our coaches are the same year and chassis - and my rears are getting slower . . . and slower . . . to retract.

Has anyone else had this vent problem? I did have a leaking seal on the shifter shaft about a year ago. But it was a very small leak. Not even enough to drip to the floor. Allison dealer replaced it and haven't had any problems since. I've not heard of the venting problem. Why would it only happen on some transmissions and not the others? There are a lot of Allison transmissions out there and this is the first I've heard of it.

Bob, I think it only applies to the new(ish) UFO chassis with the gas engine.

Norm - we had our slow jack retraction problem from the very beginning. In warm weather, they would retract within the specification time (but never quickly), in cool/cold weather they were out of retraction time spec. Two different sets of springs didn't cure the issue. One set of rebuilt jacks installed at HWH completely cured the problem and now our jacks are up in warm or cold weather within five minutes. In warm weather I have seen them retract in a minute.

It is possible you need new springs - yours could have lost their temper. If you are a DIY type, try a set of new springs. They aren't that difficult to replace and there are a couple of threads about how to replace them.
..OT end...

To the best of my knowledge, the oil leak issue is part of the Allison 2000/2100 series of transmissions. These are used in MH and commercial vehicles. The leak is not unique to the WH UFO chassis.

The rear HWH jacks on my Winnebago Adventurer LT are also slow to retract. I think it is simply due to friction. If they are very slow to retract I would suggest you check for pinched lines.

Thanks for getting back on this -- So, if I want to see if this affects my rig, I feel around the fill tube for a small vent hole, right near the top? Any other helpful info on determining if there might be a problem? Thanks

Then I stand corrected. The only place I have heard of it was related to UFO's. I have a 3000, so I don't know.
