Hi folks,

I found the source of my rattle: the bracket that holds the tranny cooler lines to the exhaust downpipe.

The metal bracket that attaches to the transmission bellhousing is loose. I can feel that there's a hole on one side of the bracket, where a bolt would attach it firmly to the bellhousing... but there's no bolt there.

The other point where it rattles is where the loopy-bracket-clamp that holds the cooler lines is welded onto the exhaust pipe. I can just reach down and jingle the whole bunch.

How should I go about fixing this? I know this can't be good for my cooler lines.

By the way, this 740GLE was converted from a ZF to an AW70L sometime in 1999-2000. I think that the conversion may have left a few things bent or missing, or mismatched?

Thanks for the help, Brickboard-buds.

Hi,


Every bracket that I've seen recently had two large (19mm Head) bolts that clamped the bracket to the engine/transmission and the engine/transmission together as well.

If your two bolts are missing, that would explain the problem.

If the area is pretty greasy and dark, spray it off at the car-wash with the pressure sprayer, that trick works pretty well. Sometimes though, pointing the wand at what you want under the car can be difficult.

If you are still unsure if there are missing parts, it might be best to post a picture (a pain, I know).


Good Luck!!

LOL I'll just stick my expensive digital camera under my cooler lines...! But really, it's good to know I'm not crazy, picking at this rattle. Do you know offhand what thread pitch/diameter/length bolt I would need?

Gaah, does this mean that my tranny could fall off???!
