Baldwin Transmission Oil Filter P/N:BT359
Baldwin Filters
Help keep transmission fluid clean and flowing with the Baldwin B252 Transmission Oil Filter, a spin-on filter with a built-in anti-drainback valve and a 20 PSID by-pass valve. It fits many vehicles and Allison transmission applications, among them the 1971-1975 Citroen SM V6-2.7L (and the V6-3.0L for 1973-1974), the 1998-2004 Isuzu NQR L4-4.8L and the 1996-1999 International 9800 SBA L6-10.8L. See the "Vehicles it fits" section for the full list.
The filter traps contaminants in the transmission oil before they circulate back through the system. Its two internal valves are built for start-up and restriction conditions, and the spin-on design suits routine service.
Cataloged for Allison transmissions and listed as a replacement for GMC 25010441. Country of origin: United States.
Interchange: GMC 25010441

What does the anti-drainback valve in this filter do?
It is designed to help keep transmission fluid from draining out of the filter while the system is shut down, so the filter stays filled for the next start-up.
What is the 20 PSID by-pass valve for?
If the pressure difference across the filter media reaches 20 PSID, for example when the element is heavily loaded, the valve opens so fluid can keep flowing to the transmission.
What are the thread size and dimensions of the Baldwin B252?
It has a 3/4-16 thread, a 3 11/16 in (93.7 mm) outside diameter and a 5 15/32 in (138.9 mm) height. The inner gasket reference is G401.
Does this filter replace a GMC part number?
Yes. The Baldwin B252 is listed as a replacement for GMC 25010441.
Will this filter fit a 1998-2004 Isuzu NQR L4-4.8L?
Yes. It is listed for the 1998-2004 Isuzu NQR with the L4-4.8L engine. Check the "Vehicles it fits" section for the other listed applications.
