How long do you think a 4l60e would last on 4-5psi of boost

Mine came with a thermostatic switch that turns it on at IIR 175*F. Since I already had it plumbed to the stock cooler and have a duramax fan blade on my Express, I put the temperature switch in the return outlet of the trans cooler. So far the fluid stays under 200*F even towing 7,000+ on a 105*F day.

I'm still pushing my stock 60e on 4-5lbs with no problems at all. It's been about 2 months and it has 215,000 miles on it I just run a tru cool 40k tranny cooler

A 60E will do about a day on boost with a trailer. An 80E will do about an engine (give or take a little), on boost, with a trailer.
I tow a LOT with my 80E and a big honkin' converter on 3.73 gears. I stay in 4th/Lockup all the time except on steep inclines when I step down to 3rd/Lockup for some extra torque. Assuming no serious headwind, I can comfortably roll 5000# on the interstate. When I go dually and 4:10 gears I should be able to pull even more.

Either way, clearly the 60e wouldn't last very long if I'm pulling a racecar behind it. Although i've considered just flat towing one to save weight.
Will any 80E be suitable for a swap? I found a 1991 4l80e for 150 bucks as a builder here in Colorado.
