Hi Marlinitic Crawlerites,

I have a brief question about transfer cases. Today, after a 20 mile drive in 2H, I backed the truck in 4LO (actually 2LO because the hubs weren't locked) into it's parking spot. When I did this, I noticed a funny grinding noise. And then I noticed that the T-case shift lever felt warm to the touch. Not hot, but noticeably warm and warmer closer to the T-case.

Is this feeling warm normal for the T-case shifter? I feel like in any case there is an oil change in the near future of this T-case.

Thanks,

Lewis

Sounds fairly normal to me. However, i'd def check fluid level and if there appears to be any metal in the fluid as it's possible some bearing(s) might be bad.

Nothing to worry about, lots of gears turning and they get warm. Make sure your fluid is topped and clean!!

I would expect it to be at least as hot as the transmission or rear differential.

Both my 5-speeds, this one in my 1986 and my old 1985, the t-shifter would get “hot” enough that I could hold my hand around the base for few seconds, and just low enough temperature that I didn’t have to let go of it immediately. I was running RedLine MT-90 in both the tranny and t-case in my '85.

The tranny shifter was almost that hot.

If you don’t know the condition of your gear oil in your transmission and t-case, change them. In extreme cold winters, I’d be using full synthetic… Mobil 1 or RedLine.

I cooled down the heat of the tranny by putting a heat shield (upside down U using home heating exhaust ducting) around the exhaust down pipe until it got to the cat.
