Technical Towing my super traditional HAMB hot rod with MY6 overdrive (a833)

I've bought a new trans for my daily (shh, it's a 68 suburban but lets call it a late '65 model).

I currently have the original bolt action 3 speed in it and don't like to travel at much over 50-55 so I got this chevy truck trans that is a mutation of dodge's a833. A lot of you are familiar with it I'm sure. What I'm curious about is if the trans is capable of surviving if I were to use the OD while towing? I don't tow in OD when using an automatic but my searches here showed a couple threads that talk about it and it seems to depend on what auto trans you use as to if it's recommended to tow in high or overdrive. Couldn't find any threads about manual ******s though.. All the automatic threads talk about big coolers and whether the bands are strong enough in different models.
The only manual trans thread I dug up was a goofball trying to tow a house trailer with a drum braked 49 merc. He had other problems to say the least.

So- Any opinions on the strength of this manual overdrive transmission? Thanks fellas

 

Those transmissions have a 3.09:1 first gear, so it shouldn't be too hard to get the trailer under way, although you didn't tell us size, weight, etc. of the trailer. They're pretty strong transmissions, so I don't think you'll have any problems in O.D. keeping it rolling out on the open roads, if it's relatively flat.

 

had 3 trucks man trans 5 sp towed in overdrive all the time, no problems,

 

It's a standard tandem axle open trailer and the 39 probably weighs less than 3000 but I'd guess its close. So towing maybe 5000 together. I just wanted to be sure there isn't a weak link that I don't want to discover out on the road.

the New process 440 , stout unit 4x4 guys like them , the weak link is going to be heat and the clutch plate , put a temp gauge on it and watch it oil gets hot ( 260*) , downshift , if you do not know the history, check the main shaft splines to make sure there not twisted or ******ed . ( 1st sign of abuse )

with the manual you do not have to worry about the pressure on the plates and weak planetarys like the automatics do .
