Just a little info for all you guys with ZF6 trannys.
Driving to work a couple a weeks ago and at about 70 mph the damn tranny locked up tighter than hell. That'll stop ya quicker than brakes. Seems the coolant lines to the radiator rubbed together at one of the clips, ruptured and dumped the 4 quarts of fluid on the asphalt. Well, 2grand later (used tranny) all's good again. So CHECK those lines...

 

OUCH! Good thing to keep in mind. I didnt know the 6 speeds had a cooler?

 

Wow I had no idea of this either. That sucks man, sorry to hear.

 

Every one of the 6speeds ive torn apart was dry. These are great trannys but nothing works long with no oil. Wonder if you could put an oil pressure switch in the cooler line or some kind of oil level sensor.

 

Sorry to hear that friend, but good info.
