Transmission temerature question?

[Leroy Eckert]

Interesting info Don. I'll add that to my manual of other goodies. I agree the
placement of the sender gives different readings. A good example is the Pyro
temp. My transmission sender is in the transmission sump and runs 170. As well,
200 degrees is in the operating range. Just makes you wonder.

The big issue is where the temperature sender is located. According to
AllisonTransOpMan.pdf, which I downloaded I think from one of these forums:

Sump Fluid, Minimum Continuous 100°F (40°C)
Sump Fluid, Typical Continuous 200°F (93°C)
Converter Out Fluid, Maximum 300°F (149°C)
Retarder Out Fluid, Maximum 330°F (165°C)
Sump Fluid, Maximum 250°F (121°C)

Based on your sump reading, it appears you are dead-on normal. Stop worrying,
enjoy traveling!
