Allison losing fluid to the Reservoir tank
I have a 2005 Holiday Rambler Navigator PBQ45 with an Allision 4000 mated to a Detroit Diesel. Let me preface this by saying I know that this is happening, I’m just not sure why its happening – I am losing transmission fluid and its going to the hydraulic reservoir. I’ve never add any fluid to the hydraulic system, yet it is always full and overflowing making a big puddle on the ground right under the overflow hose.
Meanwhile, I can top off the transmission fluid, and within a few hundred miles, its lost fluid and my reservoir is once again making a puddle under the hose and it sprays fluid on my tow vehicle that is visibly obvious.
I do have an aft mounted hydraulic pump that is engine mounted – and I’m figuring that is the problem, but was needing some confirmation from somebody that might have experienced the same thing.
Is there another pump? Something on the transmission that could be causing this?
Thanks for any and all help.
