Nope my 124k stock trans is still doing just fine. I do know how to tow and drive big loads, Forklift was balanced on the trailer so it had just enough tounge weight not to sway. And I checked the trans fluid about 10 mins after I unloaded it and it was cool to the touch. Do want a trucool 40k though!
Normally this trailer gets towed by one of our dmax's, but they were busy yesterday, and I had the trailer, so I got the job. We also normally tow the forklift behind our flatbed international 4300, so it's not like this is a normal thing, but good to know it can do it!
And No, I towed the forklift down the fwy at 60 in 3rd gear tc locked
