GMC Hydramatic

[OPCOM]

There was a used car place where the mechanic would put type F in the GM cars if they had transmission slippage issues, and they'd work fine till the customer was down the road and the money was in the bank...

Thanks Curt fo the info, I will jot it down in my record book.What you said makes lots of sense.

Ditto on making a lot of sense! I'm gonna do that with the old plow truck. Bringing it up to operating temp seems to be the other big item with making them last.

This is a heavy old truck not made for speed and high rpms, you have to remember that you dont get in it and fly like your a commuter late for work.Check your fluids walk around, look at and under for leaks , get it running, let it sit, and warm up then carefully drive it , its alot of weight, and needs to be loved. Not a little light car. Its an old heavy heavy truck made for rough terrain and heavy hauling.Its not a winner on the road, Its a winner crawling and hauling.Just my two cents for guys who dont have truck experience, dont mean to talk down to you experienced guys.

I've had good luck with running tractor transmission/hydraulic fluid, in auto transmissions, it can take much more heat before it starts to break down and it won't foam up, it also is much grabbier than most fluid, It is made to run in big power shift tranmissions in scrapers front end loaders and other machinery, a lot of guys at ramcharger.com, my Dodge M-880 has been running it for a while and It does great.
