I was wondering what kind of longevity you guys are getting out of your 2000/2500 allison transmissions. We seem to be getting 125-150K out of them, following the service recomendations to the letter.

| We have only had one trans failure on an Allison 2000/2500 most of ours have over 7000 HRS. on them. We change our spin on at every oil change and keep an eye on the color and smell as well as do an oil sample. The oil, although expensive is still cheaper than a transmission if my guys have any doubt the oil is changed reguardless of hours or miles. |

| We've been lucky to get 150K. My way of thinking is to stop wasting money on junk and buy the 3000, take care of it, and be done with it. Of course I keep buses for many, many, many years/miles! |

Most of ours are around that 6000/130000mile hour mark when they go down. Filters are changed every 12000 miles as recommended by Allison for servere duty. Fluid is changed around 40K unless it starts to smell or change colors (every two-three years depending on use). We are using only transsyd TES-295 fluid.

What is the common failure?
What are remanufactureds pricing at, before core charges/credits, in round $s? |
I may not know the answer but I can usually find who does. |

| Years ago we were swapping out 3 to 5 at545's a year and for the last 11 years we have not had a single 2000 go down till a few weeks ago. I was beggining to think they were lifetime transmisions. Most are at 150k now . Always use transynd. |

| Have a 2000 with over 200K on it. Change spin on at 25k and spin on and fluid at 50k (religiously) |

My trans jack gets loaned out more than I use it as well. I lost a couple 545s back when we had them. I used the darn jack monthly back when we had all stick shifts. Lots of clutches,syncros and blocker rings replaced. Thank Science and Allison for the automatic transmission!  |

 Amen...and for the TES295 too!!
No probs here with the 2K, even behind the DT. I know I shouldn't have said that. |

| We have two, 2500's with 125,000 on each of them. No problems on either one except leaking fill tube seals. Change the spin on filter every 10K. Go with the 3000 (world Transmission) and you cannot go wrong. Have 35 plus transmissions and some close to 200K with no issues other than the occasional output seal weeping. We did have one transmission replaced due to a Main filter Imploding (the boys from Allision flew in a transmission over night and replaced it. never heard another word from them). |

| Ours are all behind DT's 215-230hp. We are not in the mountains but certaily a very hilly partof western wisconsin. The most I have ever gotten out of a 2000 Allison was 140K (and counting). Most seem to have issues around 125K. |

| No issues to speak of on our 2500's, but we only use them on sped buses - one of them has 223K on it! Regular ed transits all have 3000's. |

My Allison dealer tells me, that you can have ABS issues that cause the 2500 to overheat, sounded kind of like what the 545's use to do. Their Tech told me it can have an ABS problem without having a ABS warning light come on.
Basically sounded like the torque converter may not go into lockup or will bounce back and forth causing fluid to overheat. when this occurs. He said the driver should notice the Rpm's changing, but of course you need a very observant driver behind the wheel that pays close attention to how bus is operating....
As I said above, so far I am very pleased with the 2000 series Trannys... the gen 1's had a few issues, but nothing major here. a few seals and some solenoid problems, but no complete failures.
All of my buses are special needs, but have had between 35-40 buses in fleet for the 9 yrs I have been here and just lost my first 2500 at 228,000 miles a month or so ago.(Torque converter sounded like a rattle upon removal)
I really can't complain, I almost forgot how to remove a tranny, it had been so long since I had to do one...

152,000 and another on bites the dust.
Build date October of 2004, so I am guessing that makes it the 2500 series?
This place has always sent out transmission replacements for reasons beyond my understanding...well...the budget says that needs to stop! I'm going to get a reman and do it in-house.
Here's my question since I've never done an electronic Allison: Do I need to put a computer on it and reset the pressures or anything? Would an older (2003) version of DOC do the job?

| We have 115 buses with Allison 2000 and have only replaced 2 ever. We are 95% special needs with 218 wheelbase conventionals of all brands. We have a lot over the 200,000 mile mark with original trannys. The 2000 has been great for us! |

| Being 95% special needs, are they subject to a lot less stop-n-go than a regular ed bus would be? |

| Yes, and the total weight I am sure is less. |

| The only resetting you have to do is reset adaptive shifts, so the new trans can relearn how it is being driven. Every thing else should be done by the rebuilder providing they are reputable.As for the question of your software I am not sure we had to upgrade our software to keep up with the new units. |

Ok, so it's not like some newer automobiles that progressively crank up the pressures to compensate for wear, then if you replace the tranny, it keeps the pressures cranked and ruins it?
That's good news if so!
The reman doesn't include a TCM, just the transmission itself. |

| When you reset adaptive shifts it also resets learned operations in TCM. We found out by trial and error when a 3000 went down because the driver put "red" fluid in the trans, I guess he thought it was water cooled. The shifts were hard and down shifts harder after reset all was well. |
