Towing an automatic (1 Viewer)

For very short towing, isn't it truck idling, transmission in P, T-case in N?

Someone (I forget who) towed an 80 without a VC for a relatively short distance, something like 40 miles.

He stopped multiple times to let it cool off, but the t-case never got more than "warm" to the touch. No negative results were posted....



That is a question though, if the truck was idling would it pump oil through the t-case? I don't think it would from what I've read....

Just thought I would add this since I know I am not the only one interested in flat towing a 80 or 100 behind a motorhome.

Good info Slee.

Username "Tuner" is the one guy I know around here who has been flat towing behind his diesel pusher for, I believe, a couple years now. Maybe he'll pop in and give us another update.

You need to be more specific.

If you mean two wheels off the ground towing, that should never be done with a VC equipped 80, period. Someone very recently posted up about accidentally doing it and having the tires start to skid within a couple blocks.

Also, even though our 91-92's have no VC, I would never allow it to be towed two wheels up. Even the wifey knows that if she ever has to have it towed, she needs to tell them, "Flat bed only!"

I'm talking about flat towing, I know there is a way, with the cruiser running, to supply oil to all the needed bearings.....or maybe someone just claimed such.

I've never done this, so please excuse my ignorance in the matter.

If the issue is needing the transfer case oiler running while flat towing...
and
If the oiler runs off of the input shaft...

Why not leave the transfer case in high and the transmission in Neutral? Or would that eat the transmission?

It will check up the transmission.

I have attached two pictures. The one shows the area on one of the gear assemblies that functions as a bearing. This is where the oil gets injected to. Now this might be ok to run in oil without the pump running, but the the problem is that if you flat tow, but the time this is going to show up as a significant temperature increase in the transfercase, it would already be seized.

The 2nd pic shows one half of the output shaft. A is the oil feed to the shaft, B is one of the many small oiling holes and C is where the front and rear shafts join. The tube transfers the fluid from one shaft to the other.

Curtis, thanks for the links on the other thread. I will post over there as well. Tuner has towed his for some time, but as you can see from the pics, there is a reason they have the oiling. Now is it needed when you tow the truck, no, but I would feel safer if I implemented a oiling system rather than blow the guts out of the transfer case when I am halfway on a trip.

Christo, thanks for your input. I was the one that tows an 80 four down, no problems.

Your pump addition is absolutely the best way to address this issue, and is now on my wish list. My long wish list.

Would you consider manufacturing a kit? Please? Pretty please?

Well, Duh - finally looked at the date of the threads. Talk about old news.

I am sure glad i did not find these threads before I towed my 80 all over the west coast - I might not have done it.
