Hi,
Came to visit our coach in Virginia for three week trip to New Orleans, and found out that, when warmed up after about 5-10 minutes, the transmission fluid leaves the transmission near the top of the bell housing.
Question: is the transmission toast, and if yes, how long does it take to get a replacement to Charlottesville, VA, and how long does it take a capable mechanic with or without a lift to replace the transmission.

Sounds like it is overfilled. Find a level (more or less) spot, crawl under
the coach after running it for 10 minutes, and where the vacuum hose
attaches to the transmission case you will find the modulator. Take out the
one bolt securing the modulator to the transmission, and pull the modulator
out with your hands. Have a drip pan capable of holding several quarts of
fluid directly under the modulator when you do this. IF IT HAS BEEN
OVERFILLED, FLUID WILL COME OUT. IF ONLY A TINY BIT OF FLUID COMES OUT, YOU
HAVE A PROBLEM. CALL MANNY TRAVEO, and ask him what is next.

Pere,
If it is inside the bellhousing, there are a couple of seals is might be.
If it is outside, it could just be the vent. What I am not sure why this would happen now.
Oh, and it is reported to take Manny about 45 minutes without a lift. I have no idea how long it would take a normal human.....

Flat rate manual says 6 hours, out the bottom. Some shops take a bit
longer, some less.

If wrong filter or bad O ring situation it may be ingesting air. The pump whips up the fluid turning it pink from red with air micro bubbles. This drastically increase the volume of the fluid/air mix and causes top over usually via vent. A bad seal would leak all the time. Start by pulling pan and assesing the filter (.075 tube) and correct O ring placement. Refill it checking level running in park to just below full hot mark.

I have already forwarded your contact information to Troy of Troy's Auto and Diesel here in Charlottesville. I am sure he will get in contact.
Thanks for the note on the refund. I'll consider the order and will let you know, probably on Tuesday, should I want one.
When would it be in Charlottesville if I order Tuesday around noon?

Most people are down for a week with a blown tranny. By the time it gets removed, issues fixed and re-installed it takes time. you are ahead of the game having a problem on a monday and not a friday.
hardest part is finding the right shop to deal with the problem correctly. our Midwest club is working at having a tranny ready to go, to lessen the downtime, but getting it hauled to where it is needed still takes time.
I think last summer, someone had a tranny swapped and back on the road in just a couple days. but that is because there happened to be a replacement tranny in the area ready to go.
good luck and report back.

I use to have a spare Manny trany in stock here but someone needed it in Knoxville, so I delivered to them. The spare never got restocked. If you are going to stock one, be sure that you keep stored where the temperature is constant year round. Otherwise in one year you will accumulate enough moisture to cause enough internal rust to make the trany unusable. Sorry but I do not have the spare any more. I need to get Manny to make us another one for stock near Chicago.
As far as how much labor it takes, I pulled mine in 1.5 hours and reinstalled it in 2.5 hours working on the floor with a floor jack. I saw Manny do it at a rally in under 3 hours. It makes a difference when you know what your are doing. Jim's book rate of 6 hours sounds about right.

When we find kinked trans lines and chipped flex plates, etc more time is
required.
At our shop we see considerable amount of these issues, even poor starter
cables.
Majority of owners have never been under it to see all the previous work
done that slowed down the R&R of any part.
That is why New Car Dealers can do things close to flat rate.

There is an update on my transmission in the 26'
Recap: Spills fluid when hot, shifts nicely when cold or hot, not
overfilled.
First garage didn't have time nor space.
2nd garage now finally (after about 7 month, said: We can do it: 5800USD
A replacement trans from Applied GMC is 1600USD plus shipping, according
to Jim H it 6 hours is the time it takes on a brand new GMC to replace
the trans, 45 minutes is the time, according to legend, it takes Manny
to replace it.
Anyone wants to fix my transmission in Charlottesville, VA for 2000USD?!

I forgot: My reasoning behind this: A rebuild kit is about 150USD, and
the Patterson rally has been cancelled, so someone might want to find
something else to do with their time :-D

Since you first posted about your problem I had my trans go out on the return trip from the Mansfield rally. My daughter and I towed it home about 63 miles with my PU truck at about 50 - 55 mph. The biggest problem was moving it backwards and parking it in my hangar.
My daughter and her boyfriend R and Red it along with the final drive and both axles. I repacked the CV joints, repacked the front wheel bearings, and replaced some seals in the final drive. None of this do you need to do.
I took the trans to Blaine Merrell's where Blaine, Diane, and I removed every part of the trans. The rebuild consisted of replacing one clutch hub that was stripped out and then we reassembled it. I have never had a GMC trans apart but it was not difficult under Blaine and Diane's supervision and help.
Your's is running, mine was broken. I am suggesting that you may have only a minor problem. Blowing fluid usually is a problem of over heating trans fluid or sucking air into the pick up tube in the pan. Before I made the decision to R and R it, I would try to fix it in place.
I would drop the pan and replace the filter looking very carefully for a possible air leak where the filter plugs in. It is a friction fit and I would put two rings or the replacement filter. Then refill with new fluid (about 5 quarts). Filter will cost you about $30.00. Trans fluid around 20 to 25 unless you choose full synthetic.
The next thing I would be looking for is a partial blockage in the trans cooler and the lines going to the cooler. I would remove both lines at the trans and blow low pressure shop air through them to see if they are indeed open. Blow air through them in both directions to make sure they are really open.
An over full or low trans fluid level can also cause this. Start the engine to allow the torque converter to fill. Turn the engine off and IMMEDIATELY pull the modulator (one bolt). if fluid comes out then you are over full. If fluid does not come out, then add fluid until it just starts to come out of the hole. Install the modulator and check the level on the stick. Fluid at the bottom of the modulator hole is the full point. Many sticks have been found to be mis-calibrated.
If the fluid is very old you might just try to change it. When I was a kid, my scout master was driving his car to upper Wisconsin with us in it. We stopped at a toll booth and could not get going again. It was blowing fluid out of the trans. He said :"damn, I knew I should have changed that fluid". He was a Phd chemist that worked for what is now BP. He explained that there is an anti-foam agent in trans fluid that wears out and causes this foaming.
We sat there for about 45 minutes and then drove away. We drove to an auto parts store and he bought one quart of trans fluid and something else that I did not see or at least don't remember. He put both in the trans and we drove off to Northern Wisconsin. A week later we drove home again to Indiana with no more problems.
A fluid change might be in order for yours.
If you have done all of the above and it does not fix it, then you are past my knowledge level. You need to talk to someone else.

Jim,
thanks for the information. Would you mind telling me what shipping is
to a commercial address in Charlottesville, VA, or if it is less
expensive a private address in Scottsville (24590)
