I can't tell you if it crosses over on the numbers but I have several vin numbers for the standard PacCar air cooler for the gear box. I'm taking it you want one for a T800. The numbers I have
are for T800. When I get to work in the morning I can post them for you at 5:30 a.m. . Those coolant over oil type if they get to leaking can ruin a gear box in a hurry. I drained one that had
two gallons of coolant in the transmission and two gallons of 50wt synthetic in the radiator, what mess. Ruined a RTLO18913A.
