DT466E - Doesn't seem to have much go.
International 3800 with the DT466e seemed to run well before i parked it late winter. Yesterday when I tried to pull it around to the front of my house. it slid around alittle in the mud, but finally got it up the hill. Anyhow, It doesn't seem like it has the power it should in drive, drove it part way across the yard and acted like it didn't have very much power. It backed back up fine though. Thoughts?
Thanks,
dave

Get it on the road for 15 minutes or more to warm it to operating temps and clear it out.

Mud robs a LOT of power.. was it revving way up as you tried to move forward? were you tilted up at a decent angle? the transmission could be a bit low on fluid.. thrans fluid expands as it warms up. so if its low. it may be low enough to slip the trans when its cold..
get the bus on level ground... start it and run the shifter from N-R-N-D-3-2-1 then back to N.. leave it running and check the fluid.. it should be on the full cold line.. if it is below then add a little.. below full cold is pretty low.. then drive it for 20 minutes or so to get the trans fluid warmed up. then check it again.. engine running afyer cycling through all gears while stopped.. it should be well between the full cold and full hot lines... also im assuming you move it long enough to get the rust off of the brake drums.. if you have air brakes, you need full pressure to fully disengage the parking brake.. and then roll a bit to get all the dust and rust off the drums which creates drag.. with disc brakes the same thing is true.. rust on the discs for the first little bit of driving..

my first thought after reading it went backwards better than forwards was that the brakes weren't releasing

It was going up hill that i slid around a little. backed onto a 2x12 and then was able to pull forward to get it unstuck. I left it there for a bit. started again to pull it forward a little to level ground a little later, and it would hardly go. let it warm up a bit and got it forward. Tonight going across the yard not really uphill much and it just would hardly go. I thought maybe i was stuck again. put it in reverse and backed up fine. I wondered if it couldn't be stuck brakes also. Is there a good way to check this? They are hydraulic discs i think.
Thanks.
How long should I let it set and warmup?

I would definitely check your transmission fluid level. When mine has been low before my bus barely made it up the driveway.

I can definitely do this, any idea what fluid it takes?

Assuming that it is an Allison transmission, look for a fluid that is TES 295 or TES 389 approved. Castrol Transmax and Valvoline Maxlife are two examples.

I checked the fluid level over the weekend, it seems fine.
There is some smoke coming out of the tail pipe that i don't remember. could this be from sitting, or does that mean something is wrong?
Unfortunately it has started to rain here. until it dries up some, i am afraid i am stuck to get out and drive it for a while.

What color smoke is coming out of the exhaust? It could just be condensation, especially noticeable in cooler wet temperatures.

Does the engine rev just fine in neutral, or is it slow to rev as well? Could be clogged air filters from sitting a long time (crud and bugs nesting).

Yes check filters, especially the fuel filter. If you did not pretreat your diesel for the cold weather storage then I would check for a clogged fuel filter.

white smoke has to me always been an indicator of either low compression or moisture in the fuel.. how much fuel is in your tank? is it possible to add some good fuel and an additive like power service diesel-KLEEN and drive out the system?
