Would you guys with HD trailer tow (option 536) look at your auxillary transmission radiator for me please and count the radiator's channels.

The towing guide indicates it should be 11 channels. 7 channels is the standard, non towing option aux radiator.

My truck indicated it has the 536 option but only has the 7 channel aux radiator. Making me wonder if I have the larger engine coolant radiator now...

Thanks,
