Some of you may remember that I lost my 1 year old Manny Tranny last month due to low fluid. I suspected my dipstick and today I started getting ready to pull the tranny tomorrow. When I removed the dipstick tube I found this:

http://www.gmcmhphotos.com/photos/data/6256/medium/IMG_20141103_121332_170.jpg

Obviously, about 1/4 of the O-ring is just plain missing.

Sigh. My bad, my fault, all on me.... Sad Embarassed Nothing at all to do with Manny other than him selling a transmission to a dumbass.

I have no explanation for why I didn't take 10 minutes and pull the dipstick tube out last summer when I noticed a big transmission fluid leak. Could have saved myself a chunk of change and lot of work. Embarassed

If I recall correctly, the O-ring was just a basic Harbor Freight O-ring from an assortment box. It should have been high temp Viton. Regardless, the broken O-ring let fluid run out of the tranny when the converter leaked down. The fluid is definitely burned. On a positive note, there is no transmission fluid in the final drive. I was concerned that the mating seals on the 3.21 might have failed.

And when I was removing the cooler lines, one of them self destructed...guerrrrrrr

I think I understand why the tranny temp sensor never got hot. There wasn't enough fluid in the pan to heat it up.

I'll get the tranny out tomorrow and next week take it down to Ken Hendersons and pick up one of the new Manny Trannys that Manny built at Ken's and left there for us poor unfortunate souls in the South that might need one.

So, what can I do to keep this from happening again. I haven't talked to Manny about this but I'm thinking there is bound to be some way to 'know' when the fluid is low while driving. Yes, I'm going to implement a front access dip stick but what if something happens while driving? Loose an oil cooler line or ?? It sure would be nice to have a gauge or warning system of some type.

Ken mentioned there is a diagnostic pressure port on the side. Perhaps a gauge or sensor there would provide an indication of falling levels. Or, new cars have a sensor in the side of the pan that detects when the oil level is low and turns on a 'low oil level' message. I don't know but there is bound to be something. Isn't there?

I don't have my GMCMI parts interchange manual handy,

Does anyone have a part number for the O ring to fit this?

That seal is way above the normal fluid level isn't it? I know there is some level of churning going on but is it really the cause?

Bob what happens is the torque converter drains down and fills the bottom of the tranny which overflowed via the missing O-ring. From what I can determine, all converters leak down but some quicker than others. When I first noticed the problem, I was 2 quarts + low. Manny said no 425 can survive that.

Larry, I don't know about the parts list but Manny said that HF has a Viton O-ring assortment.

Kerry, et al,

For your front access transmission dipstick, consider just modifying the
existing dipstick tube rather than replacing it. There's a bend in the
tube just above the FD. I drilled a 3/8" hole there, then distorted the
hole to a "warped oval" with a 3/8" rod. Into that hole I brazed a 3/8" x
12" tube, trimmed so it didn't extend but 1/32" or less into the dipstick
tube. A compression coupling and additional tubing extends the 12" to the
driver's side of the radiator.

With the minor interference inside the dipstick tube, I can still use the
OEM dipstick, with its top seal and vent (essential). For the extended
dipstick, I use a 1/8" steel cable, with the lower end brazed to eliminate
raveling and provide a markable/readable surface. I made a T-handle from
1/2" Lexan with a set screw to hold the cable at the proper calibrated
length. The "vertical" part of the T is drilled to fit over the 3/8"
tube. The small cable can share the dipstick tube with the flat original,
but if one wanted to, they could cut the original off short of the new tube.

It's worked for me for several years; your results may vary. :-)

Only the word picture. :-)

I'll check tomorrow whether it's possible to make useful photos of the
installation.

Kerry,

I'm sure this isn't the first AW S#!T you've run into tinkering with "stuff" and I'm sure it won't be the last. Hopefully Manny will
be able to rebuild your transmission.

If I were you I would inspect the chamfer where the dipstick goes into the final drive. With the final drive out you could use a
beveled grind stone like this in a drill to increase it a bit:

So, you are saying that you, or someone put in a HF "O" ring and that O ring disinigrated leaving what is pictured? I agree, in retrospect that while you (or anyone) is at it, you might as well spend the extra few pennys and put in a Viton O ring....But until now....who knew??? I would have thought that temps on that part of the trans would not be high enough to deteroriate a standard O ring....but then what do I know...

Don't beat yourself up...could be happening to me and many of the rest of us right now. Difference now is...We've been told!!

Thanks for the update.

Another possibility. The O-ring got nicked while inserting it and seperated.

I installed my tube with the front clip out of the GMC. It was a bit putzy to get it to seat correctly. With the trans installed it would be more difficult to feel if it went in correctly. It is, IMO, a wheel off and fender liner out job.

I guess you could ask NASA if correct "O" ring installation is important.
Remember Challenger? That dipstick o ring is important and it is not the
easiest to install. Kinda like the one on the transmission filter. If you
don't get it right, bad stuff happens.

I know most folks don't care for my glass engine cover but I love it. One can make a quick engine inspection anytime you want. Teri normally does that for me, looking for oil that should not be out on the engine, that we keep clean. We have saved ourselves some headaches with the 1/4 inch tempered glass, as has wally up in Omaha. Makes me feel more comfortable seeing what is going on. Oil from this dipstick problem would have blown up to where we could have seen it.
One could also put a couple of cheap cameras done there to monitor most of the engine area also.
Life is good when we own a gmc.

Jim,

If you're interested reading how badly NASA screwed up here's a link to the Wikipedia entry on the Challenger failure.

http://en.wikipedia.org/wiki/Space_Shuttle_Challenger_disaster

Scroll down to Rogers Commission and there's a sketch of the seal. Along with what they say in the Wikipedia report I remember
reading a report noting that water had seeped down n between the metal, frozen; and expanded the joint which exacerbated the
problem.

At the time a close friend of mine (Director of the Hamilton Standard Facility at JSC) mentioned something interesting about how
NASA had evolved after Project Apollo. He noted that during Apollo NASA had a "Can Do" :-) attitude. By the time Shuttle had arrived
hubris had changed that to a "We Can't Fail" attitude. :-(

As far as Kerry's problem goes I reckon the o-ring he selected could have been a bit too big and a chunk snagged on the chamfer
going in and got cut off when the tube was inserted in the final drive - been there - done that on other installations.

Kerry,

I don't mean to sound like I am contradicting anyone but my Dad had a similar experience back in the 70s with his coach.

Coach wouldn't move forward or back, terribly burned fluid. Really nasty smell.

Changed the fluid and filter. Coach would move in forward and reverse!! It worked fine.
Put about 100,000 miles on it before he sold it. Never another problem!

I would spend the cost of fluid, filter change and see if it works again.

Just my 2 cents worth.

Thing is Rick that the coach moves forward in first and second perfectly. Its only 3rd and reverse that are slipping. That points to a problem (burned disks) in the drive package (thats not the right name).

Regardless, it's out and on the ground...actually in the shop... now. I was really dreading it but now that it's over, it wasn't as bad as I was thinking it would be.

Thing is Rick that the coach moves forward in first and second perfectly. Its only 3rd and reverse that are slipping. That points to a problem (burned disks) in the drive package (thats not the right name).

Regardless, it's out and on the ground...actually in the shop... now. I was really dreading it but now that it's over, it wasn't as bad as I was thinking it would be.


Water over the dam now if it is already out.

Sorry to hear of your trans troubles.

I too just had to have trans redone. But mine was because a snap ring broke at 94k miles.
I was travelling in Texas and had to have AAMCO fix it. Frustrating because I have an extra trans and torque convertor at home!!!

Such is life. It ran great on the 1000 mile trip home.

Some of you may remember that I lost my 1 year old Manny Tranny last month due to low fluid.
So, what can I do to keep this from happening again. I haven't talked to Manny about this but I'm thinking there is bound to be some way to 'know' when the fluid is low while driving. Yes, I'm going to implement a front access dip stick but what if something happens while driving? Loose an oil cooler line or ?? It sure would be nice to have a gauge or warning system of some type.

Ken mentioned there is a diagnostic pressure port on the side. Perhaps a gauge or sensor there would provide an indication of falling levels. Or, new cars have a sensor in the side of the pan that detects when the oil level is low and turns on a 'low oil level' message. I don't know but there is bound to be something. Isn't there?


This is a most interesting question because, like many, when driving I idly wonder how the transmission is doing. I have a temperature gauge but wonder if a buzzer to sound or a light go on when pressure is low would help.

I found this buzzer sender adjustable up to 50 lbs. That seems to be low a pressure from what I read, but on the other hand it might be soon enough to stop real damage.

George, you worry too much.(grin) Look out that huge panoramic windshield,
watch the scenery go by. If there is sinister stuff happening under the
hatch, it will either get worse or not. If it gets worse, then deal with
it. A Manny Transmission will cost you the same $$$ with a small bit of
trouble as it will for a lot of it. A LOP switch that malfunctions will
leave you beside the road same as a failed engine or transmission will. It
is just one more link in the failure chain.

How is that Jim? I guess if it broke off and let fluid out perhaps but otherwise you'd just get a buzz alarm...or not.

I spoke to Manny about this and he said he has something...he was in a noisy place and I couldn't quite understand what he was saying. I'll follow up with him.

Kerry, I was referring to the LOP switches that sense loss of pressure and
open the ignition circuit. When they fail open, you have no spark. Sorry if
my answer was confusing.
