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:

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?
