Cadillac SRX First Generation Forum - 2004 - 2009 Discussion, gearbox oil hot in Cadillac SRX Forums; Hi all again
after changing the gearbox oil the message "gearbox oil hot" appears again after a run to the ...
Hate to say this, but overheating can be caused by sticking or dirty valves/solenoids etc. in the pump and/or valve body. A complete flush and a filter change might help clean up the mess. You might also have a plugged cooler or line or cross contamination with engine coolant. Check both coolant and trans oil for that.
BTW, I can't find "gearbox oil hot" in service manual. Can you elaborate?
