Lotsa heat coming from shifter knob area.. normal ?

I dunno if i ever noticed this before but while driving 100 miles to a friends house the other day in my 5.9 i noticed the shifter nob area transfercase and transmission were getting very warm.. If i touched the plastic it was pretty hot but not enough to make me move my hand.. The shifter shafts were both really warm and i could feel the heat radiating on my gas pedal leg in the knee and thigh area.. I was driving around 55-70mph on the freeway.

Last i checked my check valve is locked open i always have to prime the pump in neutral when i first start the Jeep because its basicly dry and while it does move when i step on the gas it doesnt really like it so i let it circulate for a second or two (i can actually hear it for those 2 seconds filling up) I poped off the tube and it was squirting lotsa fluid out too so its deff not blocked closed last i checked.

So yea is this normal for so much heat at these speeds ? I realise its the transmission down there but i figure driving that fast with a aux cooler and bypassed should keep that thing really cool. Plus the tranny and transmission cases themselves are being cooled from the wind of moving.. and last i checked with a thermal probe they only get to like 140f.. I imagine actually moving they might get warmer but still 140-200f doesnt seem like enough to make the floor board/knobs get hot while moving.. Or maybe Im wrong.

Very normal. The trans is inches away and so is the bell housing of the engine. Heat rises into that confined area. Mine feels warm to the touch also.

Install a transmission temp gauge.

Just so you know it's not getting to hot

If it feels to hot and you are worrying about there's a good chance there might be something wrong.
Have you checked tranny fluid lately? Have you ever serviced the tranny? Is there enough fluid? Is there too much fluid?

Not as much air movement as you would think between the tranny and body. It's all blocked off up there from the engine and the entire front end.

Also do you have an aux tranny cooler?

And I did some research and many people reported the tranny should run around 130-160 on a average day and up to 180 on hot days.

Another sign of a tranny too hot would be poor shifting so if it starts to slip or miss then you know there's a problem.

So if you are truly worried seriously consider the temp gauge

Gee, 200 deg air coming out of radiator warmed by exhaust manifolds and pipe... Why is my floor/tunnel hot?
Ya think they put those hood vents on the 9er for style.
Truth be told, even at speed the only air moving through the top of the tunnel is Hot engine compartment heat trying to escape.
The heat radiated from the tranny is pennys on the dollar.
