I have an Allison Reman PTS 2500 that is 4 years old (our of warranty). the thing appears to be leaking where the bell housing of the tranny bolts to the main body. I'm fairly confident it isn't a converter or converter seal, because I have nothing coming out of the engine bell housing. Bolts are TIGHT.
Anybody have this? How'd you fix it? Nightmare or simple job? Another reman or fix this one? |

Got him in the shop today and dropped it. Definitely leaking at that seam, not the breather vent.
Now the million dollar question...can I sit this thing bell housing up, yank the converter, and yank the front section off and reseal? Ok, I know I CAN do it, I've just never done one...does everything fall apart internally once the front section is removed or are the internals held in place by some other means?
**I'm just debating if I should send this one out** |

| I've never done one myself, but if it were me I would send it out. You already have it droppped. Just my 2 cents. |

It's Friday and I felt like destroying something, so I went ahead and pulled the front housing off. Not bad at all really.
Allison gets an F for this reman. Some clown wrinkled, folded and forced the gasket between the main housing and the spacer plate into place, then cranked it down and hoped for the best. I'm amazed it lasted this long.
Here's a pic of the great job...

I sat it up on end (converter end up), everything stayed in place. Converter housing comes off, then you have to unbolt the pump assembly from it. About 30 bolts all said and done, 4 different sizes,some have O-rings.
I ordered the gaskets from my Blue Bird dealer (Allison dealer). Didn't have in-stock, should come Friday, I'll let you know the prices and how it turns out.
I think I pay add a converter seal to the order just for safety since I'm RIGHT THERE anyways. It would make me say some bad words if that started leaking. |

| Post some pics of the assembly if it's not too much trouble. Yeah good idea to replace the convertor seal while you're in there. |

I forgot to post my pics!
https://www.flickr.com/photos/27265743@N03/albums "Allison gets an F" is the album title. It wasn't a bad job, really, just a lot of cleaning and care in reassembling so that the same thing didn't happen again. |

PTS 2500 Leaking
