If all go's well, 3 to 5 hours in a shop.

NOTE...anyone looking for a replacement or just parts for an AT 545 can have mine for free. It came out of a P-30 cubie that was running until parted out. Been sitting indoors for the past 3 years. PM if you can use it or it goes for scrap fairly soon.

Located in Houston, TX.

How long lying down in the mud?

I Know a school that has a bus that they will sell me cheap in 2 years.

About the same if your organized and have the right tools.

The 545 is basically like a big TH400 chevy trans with a throttle position cable.

Two things can cause those failures. Insufficient cooling, and or bad driving habits. That trans needs 1800 to 2200 RPM to fully lock the bands and prevent slipping.

So a driver feathering the throttle on a gravel road will cook them in no time.

I read that you can use 15w40 instead of tranny fluid. It kicks like a mule but the thicker fluid might be better for the feathery stuff. Hmm interesting. Will an intercooler help with that lightfooted gravel road travel? I plan to do a lot of bush travel

I don't I would use anything but tranny fluid, and yes a tranny cooler would help, most buses have them all ready. I have put over 25000kms on my 545, lots of gravel roads,slow driving, fast driving, and lots of hill 3-6% grades, and never had a problem
I have changed the oil and the spin on filter 2 times, next year I'll drop the pan and change that filter to.

I don't know if I'd use 15w40 in any auto trans. The viscosity is WAY too thick at colder temperatures, like 4x's as thick at 40*C, and it's only going to get worse as you near freezing. Plus the additive package is all wrong. Sure, top it off with a quart of 15w40, but as for a complete replacement, don't do it. There's more to an auto transmission fluid then providing pressure to apply the clutches(a lot more actually).

Well since I live in Canada...maybe 15w40 isn't that great of an idea. Although I will add on an extra inter cooler...never hurts. I read in the 545 manual that 15w40 is used for heavy duty applications....but I can see winter up here being a HUGE problem...lol

I have heard of straight 30 weight being used.
