What's your opinion on this?

Hey guys,

I wanted to get some opinions on my new bus. I bought a 2001 International FE w/ the DT466E and Ally Md-3060 tranny. Drove it ~1000 miles home. (Well, drove it after some MAJOR problems, more on this later) When on the Interstate, at the governed 65mph, she cruises at ~1650rpm. Pretty sure this is in 5th (OD). At the slightest hint of a hill, and I mean slightest, like maybe 1% grade it'll drop a gear to 4th, then shift right back to 5th. It does this 3 times, before staying in 4th for a few minutes, until it kicks back into OD. I'm thinking the cruise rpm's are just too low and it thinks it needs to downshift too keep the power up, but at 65 the governor kicks in a cuts engine power until it slows to about 63 then it'll kick back in. I thought I read somewhere that this engine needs a cruise rpm of 1800-2000rpm to operate at peak efficiency. Am I wrong in thinking this??

I was thinking of getting the governor taken off so she'll cruise at 70 or 75 mph, which should put me around 1800 rpm. What do you all think??

Any international dealer can change the governor speed

Hi Kubla! That was a quick reply!

I already have the ServiceMax software, just need the interface cable so I can go in to the ECM and remove the governor setting. I guess what I was more or less getting at is does that "behavior" seem normal for the ally or should I look at something a little more serious, like maybe slippage, worn parts, etc. that might require a tranny rebuild.

A fluid And filter change won't hurt a bit and a good starting point as a new to you bus.
You can smell if the fluid is burnt when you change it.
Also tranny fluid temp. Guage's would tell you a lot if you don't have one I would look into getting one as well as looking at the tranny cooler if you have one to see if the fins are stopped up with dust,dirt,debris and anything else.
Basic preventative maintenance stuff.
Good luck

Thanks Jolly Roger!

Yes, PM issues are on the plate. I guess maybe I should just get the filters and fluids changed first and then see how she operates. That might just take care of the "issue." I wanted to put Ally's Transynd fluid in it but can't find it locally, which means I'll probably have to purchase from the nearest Allison dealer which is about 2 hrs. away. I have never driven a bus of this size before, so the trip home was getting used to her! The last few months in the military I drove a smaller BB shuttling folks around, but that was 17+ yrs ago now!

As far as the tranny visually, she doesn't look to bad. The cooling lines on the front are pretty caked with gunk but I am not sure if that is from leaking lines or the engine oil that dumped all down the underside and all over the front axle (major problem referenced to in the first post). Coming home, the tranny temp gauge never broke about 200-210?, even on longer uphill climbs. This 3060 is extremely loud though. The only time I could actually hear the engine was when the torque converter was locked up in 5th, on nearly flat stretches of road or going downhill. The rest of the time she sounds like a freakin' jet engine, completely drowns out engine noise, road noise, etc. On a few of the mountain passes I manually selected 4th on the shift pad and the engine rpm kicked up to about 2100 rpm, and I still could not hear the engine over the tranny! I was just unsure if this was "normal" for the 3060. After the engine fiasco I do not have the money to get her into the ally dealer to be checked out, -sigh- so I'll start with fluids and filters and go from there!

Has anyone used Shell's Spirax S6 fluids for the tranny? It's on Allison's approved TES-295 fluid list. If so, what are your impressions? The local NAPA can order this fluid. How much does the 3060 take and what filters do I need? Sorry for all the questions but I don't have any manuals for this bus, so nothing to cover regular service intervals, types and amounts of fluids, etc., etc. Thx

I am no expert but seems a little warm to me, I drove about 200 miles when I got my bus and it I went over the continental divide the trans temp did not even brake 100 hardly.

I agree with everyone I would start with a fuild and filter change.

My gauge starts at 100 but I have the 643. It's never gone above 150. The bus following me (when purchased) has the 3060. Her gauge starts at 150, never went much above that with a severe leak (crushed hose fitting unknown at the time).
