Transmission Temperature Gauge

Yahoo Message Number: 17762
Have a 2005 Inspire #51362. Transmission gauge keeps peaking to max. temp.(300) every time I sit in traffic, or idle with the brake depressed. CC has replaced the gauge twice and the sending unit once but same problem still exists. CC says now that gauge is within specs.
Allison checked tranny and says everything checks OK, and the gauge is faulty. Has anybody else experienced this problem, and what can be done. CC basically says I have to live with it, but that would make the gauge almost wortless.

Thanks
Butch C.

Butch,

I have a 2004 Intrigue and mine does the same thing at times, not all the time. I have a brand new gauge in a box at home from last summer when I thought this was the problem. Later, Allison said the gauge is just not accurate. Apparently, the gauge sender is in a place that gets very hot under certain conditions. My silverleaf "only" reads 230-240 when the gauge is pegged. I now ignore the gauge.

My tranny guage is way off the mark that is why I got the VMSpc to see what they truely are.

I think that VMSpc reports sump temperature. Many of the guages report the temp at the output of the tranny which explains why it is higher.

Allison also gives three temp limits depending upon where it is measured. Check your Allison manual for details.

That is a good point though I believe the sending units and impedence over the distance of the wires contributes more to the guages being inaccurate. I could be wrong about that though.

Butch, my Inspire did that one time. I was heading east on I-84 after picking up the coach at JC. On the first real climb east of Pendleton (over the Blue Mountains) I pulled in to the first rest stop, early in the climb. The transmission temp pegged when I stopped. (That is also when I discovered the oil dip stick calibration issue, from the oil dripping from my mudflap and covering my toad.) The trans temp gauge settled back down again after a brief stop and never duplicated. Later, while doing a shutdown fluid level check from the driver's seat, I was given the overtemp code from the computer's memory.

I asked CC about this and they told me that it is all within limits.
I believe them. I think the gauges are simply not as accurate as I would like, but swapping them out til the cows come home won't change anything. (The fact that the fluid temp is measured just before it goes into the cooler makes things look worse than they are.)
At present, my transmission temp gauge will not go BELOW 180 degrees.
That's where it is when I start up in the morning, and it climbs to normal operating temperature as expected. Guage? Sender? Who cares, as long as it is ok at operating temperature. (I will have it fixed before my warranty runs out, however. By then, there might be a fix!)

I'm thinking part of this is the switch from Cummins to Cat. There seems to be a bit of head scratching going on, both at Cat and at CC.
The dip stick issue is a great example. How many Inspire C9 drivers out there have had their dip stick assembly replaced? It seems like it is new news to both the engine and the coach makers.

Despite the punch list issues, the coach still drives like a dream.
I'm keeping it.

IF I were to get an overtemp code from the tramission, I would certainly tend to believe it. How in the 'ww world of sports' can CC justify that an overtemp code is normal??? Tom Fisher
