Trans pan
Ok, after pulling the brand new trans pan off at least 10 times, replacing the gasket, re torqueing and re torqueing... This 300td still leaks from the pans around the bolt holes.
So, took it off and it seems to me that the outside metal of the pan in the center is actually contacting the bottom of the trans before the gasket can actually do it's job. At correct torque, I was unable to get a feeler gauge between the bottom of the trans at the top of these metal flanges (see pic). I'm thinking I'll flapper wheel that bulge down a bit to get the gasket to seal. Ideas? Also, I was able to replace the bottom guide bushing w/o pulling the spring off. Yahoo! |

Look very carefully at the whole situation before you start removing metal from bits.

Also, with a new pan (presumably unwarped) and not overtorquing anything it shouldn't leak. So have you considered if it's leaking above the gasket or dripping down from elsewhere? |

Leaking above the gasket.
Yes, after countless attempts to get it to seal, I BlueRTV'd the gasket down to the pan, because it seems like the gasket wants to 'roll' into the pan. I also diegrinded (with the 3M gasket remover wheel) all the extra paint around the top of the brand new pan, thinking it was somehow causing the gasket to not fit correctly. Yes, torque'd correctly, to inch lbs, barely hand tight. After putting the pan on, filling the trans, it won't start leaking until I start the car. Then... drip drip drip from right above the center bolts. Right where that metal flange hits the bottom of the trans. Also, Army, I looked at the clearance of the filter. It does not seem to be hitting or obstructing in any way. |

yup, feeling dumb...
So, after repeated R&R's on this trans pan, I finally clued in to what Yak was saying. I took 'above gasket' to mean btw tran and gasket, not that it might be leaking from somewhere completely dif than the pan.... Doah!
So, cleaned everything above the pan really well, filled it up, started it, and checked for the leak. The drip comes out right below that green bit in the pic, only when it's running. It seems that's where it's leaking from. You can just barely make out the wetness on the back part of the trans flange. Solutions? |

Well, best I can tell, from under or behind that green part....

My blurry photo recognition skills are off. I'd call Phil or whunter and describe the problem. They've probably got a gasket or O-ring for that part.

Which side of the picture below (of my 722.118 transmission) is your leak coming from? ![]() Left hand side of the picture => rear end Right hand side of the picture => front end Bottom of picture => driver's side

The green thing is the modulator, it's located on the left (drivers side) of the transmission.
At least I'm fairly certain, (722.3xx) not sure what year it is, katumba1, please put your car in your avatar or signature.

Ahhh that'll be the red thing in my picture then? We are talking about the vacuum modulator then? If so that's on the opposite side on my 722.118...

I believe so Army, the 722.118 seems to be on the right side and is red.
BTW, do you have a Euro or North American?

It's my buddy's 82 300dt that I'm working on.
In that pic, I'm looking up at the left side of the trans, facing back (drivers side, facing rear). By the look of the trans and the fasteners holding it in, the trans seems to have been recently pulled. No idea what was done to it. Really appreciate any input on this. It's sitting up on jack stands on my side driveway. I'm in Vegas. The heat is coming... If I've got to R&R the trans, rather do it sooner rather than later. |

OK it sounds like you've got a newer transmission than the picture I posted.
If you have a quick search on the internet I reckon you'll find plenty of data (some of it written by ATSG) on the 722.3 transmission. You should then see roughly where the most likely place is for a leak to come from... ...I can't help anymore so I'm banging out!
