Mack T2090 gearbox leak from cover

[Ryon Hess]

Anyone encountered a cover leak on there gearbox before? I think it’s even spraying a little by the specks on back of cab and fuel tanks nearby. Maybe breather is clogged and pressurization would explain the spray or a worn gasket? Maybe tower is loose also? When truck was ran first time in 8 years local shop thought the cover was issue but that didn’t fix.

Ryon,,,  since you have another post, about not getting into reverse, I would pull the shifter off the tranny and check it for wear.  check the bushings for the shifter shaft.  hopefully the service kit is available,  and re-build it..
