Flat towing Humvee with 40,000 lb military tow bar

[TNDRIVER]

I have rebuilt a 4L60 that had ratchetted the pawl and it was for about 10 secs... it looked pretty bad when I got it out. Had to replace the sun shell also.

If you happen to pull apart one of the late model 4l80e's we need to chat.

Well... this is the week I flat tow the M1151A1 about 300 miles.. Using the 14k tow bar and all parts recommended. I still can't decide if I need to pull those drive shafts or not but I think I want to hit the hwy for 5 miles and check the temp of the Tcase... then go 30 miles and check again and so on. I will definitely update (with pics) everyone on what happens. I have been looking for a wireless temp sensor to stick to the T Case that can communicate with my phone but haven't found anything that could give me live temp data as I drive. Any ideas?

It has been some 25 years ago, and things were a bit different back then referenced to "legality".

Twice I flat towed w/military towbar HUMVs from Phx to Oakland, Ca with a big rental box van. Figure some 900 miles, with a Mutt in the back of it, too.

B4 and at several stops checked tires & oils. No problems, no "Forced" stops, and no regrets. No plates on it, either.

C'est la vie.

Thank you for the info...
Did you pull the drive shafts to flat tow? These must have been the 3 speed trucks?
