Transmission temerature question?

[Don Bradner]

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!
