Back at it again after a break for family/homestead priorities. Hoping to change out the transfer case and transmission fluids this weekend. Would like opinions on what you guys like to use.

Non detergent SAE 30 is what mine has. NAPA seems to be the only source around me that has it, usually less than $4/quart.

Be sure the oil you go with is safe to use with yellow metals (bronze?).

Generally 80w90 Gear Oil - and like @HDN mentioned - be sure to be sure that it is good for use with bronze / brass gears syncro's.

Maybe up north where you are a lighter weight oil in those gearboxes are required as mentioned by @ToddJK ?

I'll say I haven't had issues with stickiness or difficulty shifting when it was cold out, but I imagine in warmer temps, the non detergent SAE 40 would work too. It may not sound as ideal as some other fluids, but it is what Spicer spec'ed for their tranny and such and it is bronze safe. Only downside is the tranny and transfer case will get quite a bit warmer on long drives especially at the top end of RPMs. The t-case lever is usually my indicator how warm the t-case is getting and it will be hot like a cup of coffee cruising at 60mph or above, 55mph and below, it's pretty warm but not hot

Nice to know. Back in the day, we used 80/90 in all the gearboxes on Deuces, 5-Tons, the Internationals, GMC's, Dodges and to be completely honest - anything else that we had that needed gear oil. I'm sure that was a plan to simplify the lube orders. Three oils covered everything that way.

Thinking back, I can remember that the T-Case handle was a way to "feel the temperature" on a long ride to somewhere. One of our jobs was a local and our internal trucking folks were slammed. We drove about a hundred vehicles from Charlotte to Albemarle (NC) to get a job started. Hand to the transfer case handle every now and again was a nice way to "keep an eye on things".

Happy New Year to all! Been too busy to do much on the truck but I squeaked in a couple hours over last week to get 3 of my newly mounted wheels in the bed using my engine hoist, got the 4th mounted in the spare location, replaced 2 battery terminals and got a battery equalizer to install. Fired right up in 34 degree weather just like always. Also mounted a license plate.
