Towing with an AT545?

Hey all, Here's a bit of back story. I'm looking at a 2001 40ft dognose with a DT466 and an AT545. I'm also intending to tow an enclosed trailer with a subaru forester.

So that brings me to my dilemma. From everything I have found on this forum and elsewhere, the 545 is not bad but it's not great. In my particular application, it is leaning more towards the "not great" side of things. Am I right in thinking this? I'm understanding that it will be prone to overheating and not a ton of power... especially in any sort of hilly environment.

I'm thinking I might have to keep an eye out for a better transmission and I'm posting here in hopes of either validation that I should stay away from the 545 or information that might allow me to make a 545 work.

So any thoughts on the 545 in a 40 footer that's towing a car? Thanks in advance.

My bus is 35 feet long, weights 15500. The Jeep I haul is 4,000. I have the 545 & plan to drive it till it blows.

thats an odd combo. i would think the dt466 would overkill a 545. just saying.

i'm a 545 owner, add a transmission cooler, i did and i can tow with enough power to accelerate uphill now. it made a huge difference.

i live on the colorado plains, so pretty much everytrip i take has a few big hills in it.

I have a full size, t444e with at545, I haven't towed yet, but I plan to tow my chevy sonic and I'm not worried at all, just make sure you have a cooler, and do tranny oil changes.

My shorty with 444/545 seems like it would be ok to tow a decent load. As long as big hills and high speeds aren't involved. I've not driven a full 40' bus with this engine/trans combo, but I wouldn't imagine it would be great.
A tranny cooler and accurate temp gauge would definitely be things to do if towing with this setup, imo.

Just made a Pensacola to Crystal River (mostly level) weekend run with buss full of household and garage stuff in the bus. Pulling a 27 foot travel trailer.
75 to 80 during drive down interstate going no faster than 55 to 58mph.
Stock temp gauge showing 180 most of the time and 195 once in a while after a long but slow rise in the hwy.
Laser handheld showing 180 engine oil pan temp and 145 tranny pan temp.
466e and 545 tranny, 2300@55mph.
Return trip w/o trailer and empty ran 175 to 180 all the way back per dash gauge.

Wow thanks for the replies, guys. Seems like I may have spent a lot of time worrying about nothing. I appreciate all of your input.

Double07, that is quite the setup! makes me feel a bit more comfortable about my own plans seeing your success. Do you have an additional cooler installed or no?

GBStewart, EastCoastCB, and turf, I am starting to see what you guys are saying about additional cooling and temp gauge. That is great advice and I appreciate that. I had not even realized (silly me) that that was an option but now it seems so obvious.

Thanks all for the help!

We live at 4000' and tow up and down mountains every trip. The 545 is just fine.

My bus is 100% stock. I only bought it to make the move as I plan to sell it after done moving. I figure I will at least break even.
But the experience has got me hooked on doing a conversion on a more desirable bus.

Screw your high jacking prices Penske.

maybe i too worry too much about running my shorties with 545's in the mountains.... if people are towing cars and big arse trailers all over... maybe i could run one through the big mountains.. ive run mine through the east-of-the-missippi mountains but never the rockies..
